Construction Spending IS NOT Construction Volume.
I read an analyst report this week that stated construction jobs growth isn’t keeping pace with construction volume growth. The reference appeared to be to construction spending. That fails to convert construction spending to construction volume, so compares apples to oranges. Spending must be adjusted for inflation to get real volume growth. Jobs MUST be compared to volume.
For over two years now, construction volume growth has not supported construction jobs growth we’ve seen. I expected jobs growth to slow down. I’ve been saying this for over a year. This sure looks like it.
For 2018 jobs growth averaged over 300k. Since January 2019 the rate of jobs growth has dropped from 300k to 150k.
Current projected new starts data IS NOT supporting construction volume growth for the next 2 yrs. Growth of 3%/yr in non-building infrastructure will be offset by declines in residential buildings and flat nonresidential buildings. Therefore, there is no real volume support for jobs growth.
This plot adjusts construction spending by taking out inflation to get real construction volume growth. Last year of real volume growth was 2016. Yet jobs continue to climb. This can’t continue. The plot above shows it has slowed.
Construction jobs growth has slowed considerably over last 2Q, as expected. While construction jobs are up about +150k in last year, jobs increased only +45k in the last 6 months. I’m expecting this trend to continue. In fact, I wouldn’t be the least bit surprised to see in the near future some months when construction jobs decline. The fact is, construction volume simply does not support jobs growth.
Total construction volume, spending after accounting for inflation, has been down for 5 of the last 6 quarters. Volume peaked from Q1 2017 to Q1 2018, but the last year of real volume growth was 2016. Volume is flat or down while jobs continue to rise. This can only mean contractors will be at risk of being top-heavy jobs if a downturn comes.
Construction spending annual rate will increase by 3% in the next 12 months, but volume in constant $ after inflation will remain flat. In Q42020-Q12021 spending slows to less than inflation, so volume begins a modest decline. Growth of 3%/yr in non-building infrastructure will be offset by declines in residential buildings and flat nonresidential buildings. Jobs will continue to grow and spread the imbalance even more.
The construction jobs slow down has been in the cards for a long time. With all the talk of skilled labor shortages, there’s been little discussion of the unsustainable excess jobs growth. Maybe it’s about time to change the conversation.

In early 2007, residential construction volume had already dropped 20% and total construction volume was down 10%, (the annual averages would not show this dramatic drop but a monthly plot would), yet construction job openings and labor turnover survey (JOLTS) was peaking at a 6 year high. From Jan 2007 to Jan 2008, construction had already lost 250,000 jobs. All of that was in residential construction. At the time, nonresidential construction was still growing.
Nonresidential buildings volume would peak in late 2008 and non-building infrastructure peaked in early 2009. By that time, in Q1 2009, residential volume was down 60%. Even though nonresidential construction was peaking, total construction was down 25%.
In 2008 construction jobs declined by another 500,000, about 90% residential jobs. JOLTS dropped to half of the 2007 peak high. It was over the next year or so that all construction began to decline, jobs would drop in all sectors and JOLTS would plummet to an all-time low.
The point is this: The construction recession began with the decline of residential construction in 2006-2007, at a time when JOLTS was at a 6-year high. Jobs declines lagged the decline in real construction volume (the annual average plot shows this well).
It is remarkable how residential construction volume from the Q1 2006 peak to Q1 2007 had dropped 20% but residential jobs increased by 6%. JOLTS was peaking at a 6 year high. Although total construction jobs increased in 2006, jobs started to decline in the 2nd half 2006 and would drop 200,000 in 2007. JOLTS continued to show job openings increasing from mid-2006 to mid-2007. Neither jobs growth nor JOLTS reflected what was occurring in real construction volume and certainly did not give any leading indication of what was on the horizon.
The AGC survey of contractors has been reporting difficulty hiring construction labor every year since 2012. Yet from May 2012 through May 2019, construction added 1,870,000 jobs, an increase of 33%, the 2nd strongest jobs growth period ever recorded, not far behind 1993-99 when jobs and volume grew equally (JOLTS was not tracked before 2000). In the four years 2003-2006, just prior to the great recession we added 1 million jobs and volume growth kept up with jobs for the first three years, but then the residential recession started and volume began to plunge. However, JOLTS increased from 2003-2007. These three periods mark the best periods of jobs growth in the last 30 years.
During the last seven years, unlike 1993-99 or 2003-05, when jobs and volume grew equally, construction volume (spending minus inflation) increased by only 22%, far less than the 33% jobs growth. While contractors continue to report difficulty filling jobs, the pace of jobs growth is near an all-time high and is out-pacing the growth in volume of work to support those jobs. JOLTS increased every year during this period.
Now fast forward to 2019. Construction spending growth for the previous two years, 2017 + 2018, increased 4.5% + 5.0%. But inflation during this period was 4.4% + 4.8%. Real construction volume for the last two years increased less than 1%. But jobs increased by nearly 8% and JOLTS more than doubled from 2016 to the end of 2018.
This is a real head-scratcher. Volume has not increased for two years, yet jobs are up 8% and the indicator for job openings is increasing. This is not at all what the data should be showing.
In fact, from the 2006-2007 pre-recession peak until now, non-supervisory jobs have recovered to within 7% of the previous high, but construction volume is still 18% below the previous peak. Total all construction jobs is only 3% lower than the pre-recession high.
Just as the data showed in 2007, the data at the start of 2019 shows that we are top-heavy construction jobs that are not supported by real growth in construction volume.
8-3-19 > added plot > Plot below shows the same data as the above two plots, only plotted monthly, with all data from 2001 thru 2019 on one plot. From 1991 to 2000, jobs vs volume disparity was only 1%. This plot sets Jan 2001 to zero baseline for both jobs and volume. By Dec 2006 the disparity was 20%. This plot shows construction jobs growth vs volume growth now has a wider disparity than Jan 2007 when we were leading into the Great Recession. By far, the largest portion of this growing disparity is residential. In the last 24 months residential volume has decreased by 12% but residential jobs have increased by 7%. To be fair, that doesn’t include some nonresidential jobs that were actually doing residential work.
Construction volume, (spending inflation adjusted to constant $ volume) hit a 3-year low in Dec-Jan.
8-3-19 > added 12 month trailing jobs plot. Jobs growth rate, although showing some minor up months, has been declining since Q3 2018. As of July 2019, the 12 month trailing total of new construction jobs has dropped almost 50% in 9 months. If we maintain the current rate of jobs growth (avg 15k/mo in 2019), within the next three months we will hit a six-year low. I’m expecting growth to slow, so we may hit that six-year low next month, in the August data.
With construction spending in 2019 predicted up only 2%, and forecasting 4.5% construction inflation for 2019, real volume for 2019 will be down 2.5%. Jobs thru April are already up 1.2% year-to-date. So the gap is widening.
We are in the third year of no increase in construction volume. But jobs have continued to grow and JOLTS is at an all-time high. These data sets should not occur at the same time. But this is exactly what occurred prior to the great recession after which we experienced a devastating drop in jobs. However, compared to the construction volume measured by inflation adjusted spending, both the changes in jobs and the JOLTS indicator of job openings seemed to lag real activity by about a year.
Even if we do not experience a construction recession similar to 2008-2011, the current situation may be signaling that we could experience a jobs correction with the slightest downturn. If a jobs correction does not materialize then we are headed for a period in which we will solidify the highest ratio of jobs per volume of work put-in-place as measured in the last 50 years.

For the two years 2017-2018, the Total All Construction posted Revenue +9.8%, Volume after adjusting for inflation +0.3%, and total Jobs +7.6%.
Breaking out these numbers by sector,
Nonresidential Buildings — Revenue +5.9% Volume -3.1% Jobs +8.2%
Non-building Civil — Revenue +3.8% Volume -3.6% Jobs +10.0%
Residential Buildings — Revenue +17.1% Volume +5.6% Jobs +8.2%
Similar to a pattern that occurred in the pre-recession spending boom, jobs growth is more closely matched to revenue growth than it is to real volume growth. Overall, for the last two years, construction jobs growth far outpaces construction volume growth.
In the nonresidential sectors, while revenue was positive, after spending is adjusted for inflation, real volume was down 3% to 4%. Yet jobs increased 8% to 10%.
Residential spending (revenue) was up 17%, but after inflation real volume was up only 5.6%. Residential jobs increased 8%. If we look at residential since 2011 we see persistent growth in volume greater than jobs. But all residential jobs are not captured.
When we look at Nonresidential Buildings we see jobs growth far exceeds volume growth. However, there are some jobs related to residential work that are captured in the nonresidential jobs number, any work on high-rise residential buildings performed by contractors whose company is generally classified as nonresidential, particularly structural, and it is impossible to break out those jobs.
It is difficult to square the consistent jobs growth in excess of volume growth with the long ongoing narrative of jobs shortages. I suppose it could be argued that it is a “skilled” jobs shortage, a lack of workers with the needed experience. But we would have to look back to the period 2000-2004 to find a time when jobs growth was balanced with volume growth. There are several other articles on this blog documenting the variance back to 2000.
Here’s a link to a twitter thread on the May release of the April Jobs report showing the differences for the last 12 months.
A brief explanation added to answer the question of the difference between Spending (or Revenue) and Volume.
If your company revenues are increasing at a rate of 7% per year at a time when construction inflation is 5%, your business volume is increasing only 2% per year. If you hire support staff to support 7% growth in revenues, you would be grossly over-staffed. Inflation adds nothing to business volume. If you do not factor inflation into your growth projections, you are not forecasting growth properly. Spending is revenue. Volume is spending (revenue) minus inflation.
If a contractor is building houses that last year cost $250,000 to build a 2500sf house, but this year it cost $275,000 to build the same house on the lot next door, the volume did not change. Both sets of dollars represent the cost of the same house, but the most recent house cost 10% more due to inflation. It does not take any more workers to build the house this year than it did last year. Inflation changed the dollars of revenue that changed hands, but inflation added nothing to business volume.
Volume is measuring the amount of work completed, not the cost of the work completed. This blog post compares the number of jobs added to the amount of work added. Adjusting for inflation removes the variable of cost.
In the 24 months from May 2016 to May 2018, Construction Volume went up 3.0%. Jobs went UP by 8%, 500,000 jobs. Spending in that 24 month span increased by just over 12%, but inflation for that period across all construction averaged 9%, hence real volume increased only 3%. That’s a $35 billion increase in volume, enough new work to support 175,000 to 210,000 new construction jobs.
JOLTS (Job Openings and Labor Turnover Survey) job openings went up from 2.4% to 3.0%, up 50,000 openings. Jobs growth exceeded volume growth by more than double and yet job openings went up!
Not only did jobs growth of near 8% far exceed that needed to support the growth in new work, but also, because jobs growth was so strong, it should have reduced job openings.
What’s wrong with this picture?
Pretty obvious the numbers just don’t add up. First, since construction spending is always later revised up, in recent years by 2%, let’s be generous and assume spending will get revised up by 2%, and let’s keep inflation the same. That would result in a 5% increase in volume or closer to $60 billion in volume. That would support 300,000 to 360,000 new jobs, a need still well below the actual growth in jobs of 500,000.
No matter how we look at it, even generously supposing spending will later increase by 2%, jobs have increased greater than volume of work.
Companies predict job openings based on positions they need to fill within 30 days. But, what if their judgement of positions they need to fill is determined based on what they anticipate from increases in revenue, without taking inflation into consideration. Since revenue also includes inflation, which adds nothing to business volume, that would overestimate the need for new jobs. We’ve seen this before, in the last expansion.
2003-2006 construction spending increased by 35%, the most rapid increase in spending in over 30 years. But construction inflation during that four year period totaled over 30%, the most for four consecutive years dating back to 1978-1981. After adjusting for inflation real volume in 2003-2006 was up by less than 5%. Considering how high spending was and how much it felt like growth, there was surprisingly little. That did not hold back jobs expansion.
Construction firms added 15% to jobs, or 1,000,000 jobs during this period, more than 3x the actual need. Job Openings in the JOLTS report increased 100%+, from 100,000 to over 200,000. Firms hired far more than needed and kept increasing the report of job openings, even though they had already hired far more than required. In 2006, housing starts dropped 15%, residential spending dropped 25%, but residential jobs still increased by 6%. From 2003 to 2006, spending on nonresidential buildings increased by 20%, all of it inflation. Volume remained stagnant these four years, however jobs increased by 10%.
Clearly the increases in jobs during this period correlate more with spending than real inflation adjusted volume growth. This four-year period registered the largest productivity decline in over 30 years because the rate of jobs growth was much faster than volume growth.
For 2018-2019-2020, construction spending is currently forecast to increase 6.7%, 3.0% and 4.2%. But after adjusting for inflation, real construction volume is predicted to increase only in 2018 by about 2%. For 2019-2020 volume declines or remains flat.
An argument could be made that JOLTS openings is dependent on firms outlook for growth in the near future. For that, let’s look at predicted volume growth in 2nd half 2018 and in 1st half 2019. It is predicted spending will increase 1.5% in the 2nd half vs 1st half 2018. But adjusted for inflation, volume will decline by 1%. Likewise, for the 1st half 2019, although spending will increase, inflation will outpace spending and real volume will decline 1%. There is nothing in past data or forecast that would support an increase in forecast job openings.

Could it be that some firms are anticipating job needs based on spending, not on volume? Could it be that these firms are not adjusting revenues for inflation to get volume before using the data to prepare a business plan? This is not entirely anecdotal. In several presentations I’ve given over the years I’ve asked the audience, How many of you plan your business needs on your revenue? In a show of hands at a presentation to NHAGC, a large portion of the audience raised their hand.
If your construction company revenues are up 6% in a year when inflation is 5%, then your net volume is up only 1%. Your company jobs growth required is only 1%.
You cannot ignore the impact of inflation when forecasting jobs need.
Jobs report for June issued this morning. Construction Jobs are up slightly. But the real story is in the last year of growth. Jobs are up 282,000 since June 2017. All across the industry, pundits are screaming jobs shortage. But is there one?
The current spending growth has 2018 on a path to reach an increase of near 8% in spending. But that is not volume. Most of that is INFLATION and that ADDS NO VOLUME. Inflation in 2018 is predicted (already in the spending numbers) to come in about 5% to 6%. Volume is spending minus inflation. Volume in 2018 forecast 2%-3%. Jobs are up 4% since June 2017.
Jobs growth of 4% when net volume is increasing only 2%-3% shows jobs growth in excess of volume. In 2017, jobs increased 3.4% against spending growth of 4.5%. But ALL of the spending growth was inflation, so net volume was 0%. So jobs growth has outpaced volume growth for the last two years by 5%.

This plot sets the plot lines to zero starting at Jan 1, 2011 so the growth from the bottom of the recession can be visualized. We started Jan 2011 with an excess of jobs.
The plot below shows from Jan 2005 through Dec 2010, volume had dropped 15% more than jobs. So we started the recovery in 2011 with excess jobs compared to 2005.
When we look into the three major sectors, the numbers show shortages in residential and job excesses in nonresidential building and nonresidential infrastructure.
You can read much more detail on this in several other articles I’ve written. See this link Construction Jobs 3-8-18 for an article that includes all links to previous articles on the Jobs/Workload imbalance, has an explanation of how some residential jobs are counted in nonresidential and shows the volume/jobs plots for residential and nonresidential.
Residential construction jobs currently total 2,817,000. That’s 83% of the peak jobs year, 2006, which averaged 3,405,000 jobs. Volume of residential work, after adjusting spending for inflation, peaked in Q1 2006 at $780 billion. Volume in the 1st five months of 2018 averaged only $540 billion, only 69% of peak volume. Since the peak in 2006, residential jobs are at 83% of peak, but volume is only at 69% of peak. If we look only at growth since the bottom in Q1 2011, residential jobs have not kept up with volume growth. However, jobs have increase far more than volume compared to the previous peak.
Nonresidential building construction jobs currently total 3,388,000. That’s 99.7% of the peak jobs year, 2007, which averaged 3,397,000 jobs. Volume of nonresidential buildings work, after adjusting spending for inflation, peaked around Q42007-Q12008 at $530 billion. Volume in the 1st five months of 2018 averaged only $420 billion, only 79% of peak volume. Since the peak, non residential buildings jobs have returned to previous levels, but volume is only at 79% of peak. Nonresidential buildings jobs, whether we look at just from the 2011 bottom or we compare since the 2007-2008 peak have increased far more than volume.
The following link shows the jobs vs volume plots for residential and nonresidential.

The AGC survey of contractors has been reporting difficulty hiring construction labor every year since 2012. Yet from June 2012 through June 2018 construction has added 1.5 million jobs, the 2nd strongest jobs growth ever recorded. It is 2nd to 1994-1999, the strongest construction expansion on record. We are currently in the 2nd strongest expansion, about equal to 1994-1999, but substantially stronger than 2000-2005.

Brief notes on spending, starts, backlog, jobs and inflation from March and April tweets.
Nonresidential construction spending is not decelerating in 2018. Will see best growth since 14% in 2015.
Residential construction spending is slowing to +7% growth in 2018, after 6 consecutive years of strong growth averaging 13%/year.
Non-building Infrastructure forecast growth of 8% in 2018, potential to hit a new all-time high due to very large projects in Power and Transportation.
Public construction spending in 2018 is forecast to reach $307 billion, an increase of 8% over 2017, the best growth in 10 years. Educational and Transportation will contribute equally and together account for more than half of the Public spending growth in 2018.
In Oct 2016 and again in Feb 2017, I forecast Manufacturing spending would fall 13% in 2017 after hitting peak spending in 2015 from massive growth in new starts in 2014. At that time, the AIA consensus forecast (average of seven analysts) was that spending would increase +0.4%. By July the consensus had been revised to average -6.6%. I updated my forecast to -11.8%. Based on cash flows, from April 2016 through the end of 2017 I expected spending to decline in 17 of 21 months. It declined in 14 of those months. Manufacturing spending finished 2017 down 11.9%.
In Fall 2017, I predicted Manufacturing construction spending would increase +9% in 2018. However, through March, total construction starts for Manufacturing over the last 12 months would count as the 2nd highest year on record. Therefore I’ve recently revised my forecast up to +13% spending in 2018. I’m now expecting double digit % spending growth in both 2018 & 2019. The January 2018 AIA consensus estimate is for +2.8% increase in 2018 spending and +5.2% in 2019. Some analysts predict 2018 spending will decline. My data shows increases in starts and backlog indicate large gains.
Nonresidential Buildings new starts are up 55% in four years. 2018 starting backlog is the highest ever, up 24% in two years.
Nonresidential Bldgs 2018 starting backlog is 55% higher than at the start of 2014, the beginning of the current growth cycle. Spending is UP 38% with 2018 spending forecast up 9%. Institutional accounts for 52% of 2018 construction spending growth, Commercial 27%, Industrial 21%.
80% of all nonresidential buildings construction spending forecast in 2018 is already in backlog projects at the start of the year.
New Construction Starts are booming (need to look past the mo/mo and ytd)
- Residential – 2 highest qtrs since 2006 in last 12 months
- Nonres Bldgs – 3 highest qtrs since Q1 2008 in last 15 months
- Nonbldg Infra – highet qtr since Q1 2015 peak in last 6 months.
Construction Starts data is regularly misinterpreted in common industry forecasting articles. Starts do not directly indicate changes in spending. A Forecast Cash Flow from Starts gives an indication of the rate of change in spending.
Educational new construction starts total from the last five months of 2017 posted the highest 5mo total starts in at least seven years, 13% higher than the next best 5mo. Jan 2018 monthly spending up 12% from 2017 mid-year low.
Healthcare construction starts have quietly increased to a record high over the last two years, up 30% for the 12 months through August 2017 vs the previous 12 months. Spending will increase slowly.
Amusement/Rec construction starts avg of +15%/yr for 5yrs, up 30% in 2016, 5% in 2017. In last 6mo, Aug 2017 to Jan 2018, four very large billion$+ projects started, almost a year’s worth of new starts in 6mo. Backlog indicates 15%-20% spending increases for 2018 and 2019.
In 2010, Warehouse new construction starts were only 1/3 of Store new starts. In 2018, Warehouse starts will be 50% greater than Store starts. Warehouse starts have increased between 20%-40%/year for seven years and are now five times greater than in 2010.
Lodging starting backlog up 13% for 2018, having already averaged increases of 30%/yr since 2015. Starting backlog jumped from $7 bil/yr in 2014 to $17 bil/yr in 2018, supported similar spending growth. Although 2016 was peak starts, it looks like 2018 will be peak backlog.
New construction starts for Manufacturing total for the last 12 months would count as the 2nd highest year on record. I’m now expecting double digit % spending growth in both 2018 & 2019. The consensus estimate is for +2.8% increase in 2018 spending and +5.2% in 2019. Some analysts predict 2018 manufacturing bldg spending will decline.
Structural steel contract includes structural shapes, steel joists, metal deck, stairs and rails, about 10% of total building final cost.
Other steel in a building can include reinforcing steel, exterior metal wall panels, metal ceiling frames, wall studs, door frames, canopies, steel duct, steel pipe and conduit, about 6% of total building cost.
All steel (in a structural steel building) is at least 16% of total building cost. There are more hidden costs of steel in mechanical, electrical and plumbing equipment.
Raw mill steel is about one fourth the final cost of structural steel installed. A 25% increase in cost of mill steel could raise a structural steel subcontract bid price by 6.25%. At 10% of total building budget, that would raise total building cost by 0.625%.
A 25% increase in cost of mill steel could raise the other nonstructural steel costs by 6.25%. At 6% of total building budget, that would raise total building cost by 0.375%.
A 25% tariff on mill steel raises building cost inflation by at least 1%. That’s about $7.5 billion of unexpected cost inflation just in 2018.
Watch for unexpected impacts from steel tariffs, potentially adding 5% or more to total cost of bridges (plate steel). Also impacted, power industry, pipeline, transmission & communication towers, transportation.
Steel tariff could inflate the cost of the proposed $2.1 billion Gordy Howe International Bridge by $100 million. That would hurt the budget.
2018 Construction Spending Forecast – Nonresidential Bldgs construction spending in 2018 forecast to reach a new high, $459 billion, up 9% over 2017, passing the previous 2008 high. In constant $, 2018 will still be 18% below peak.
An estimator could be far off when indexing construction cost using a general cost index versus an actual selling price index.
Failure to account for the affect of inflation on the cost of construction could result in a failure to be profitable.
For the last 4 to 5 years average inflation for nonresidential buildings is 4.5% to 5%.
For the last 4 to 5 years average inflation for residential buildings is 5.5% to 6%. In 2013 it reached a 12-year high of 8%.
If you are hiring to meet your needs and you see that construction spending (revenue) has increased by 25%, do you hire to match revenue? No! Hiring requires a knowledge of volume growth, and revenue doesn’t show that. Revenue minus inflation shows volume.
Construction activity has a direct influence on construction inflation. Nonresidential Buildings and Non-building Infrastructure backlog are both at all-time highs.
Construction Jobs vs volume growth the last 5 years is nearly even, yet jobs imbalances exist within sectors. Nonresidential Buildings and Non-building Infrastructure show excess jobs while Residential shows a severe jobs deficit. But not all of the apparent deficit in residential jobs is real.
Are all residential jobs being counted? Several studies suggest that a large portion of residential construction jobs may be held by uncounted immigrant or day labor. So it’s possible the residential jobs deficit may not be as large as shown.
In addition to uncounted immigrant labor, some labor is mis-classified. Take for example, a high-rise multi-use building with commercial retail, office and residential space. Census definitions of spending classifications break out spending into the 3 market sectors, but the building is built by high-rise contractors (probably normally classified as commercial), not a residential contractor. This is residential space built using labor classified as non-residential commercial.
BLS writes this: “Establishments are classified into industries on the basis of their primary activity… For an establishment engaging in more than one activity, the entire employment of the establishment is included under the industry indicated by the principal activity.”
So, the mis-classified labor reduces the nonresidential excess and offsets a portion of the residential shortfall.
Construction added 1,339,000 jobs in the last 5 years. The only time in history that exceeded jobs growth like that was the period 1993-99 with the highest 5-year growth ever of 1,483,000 jobs. That same 1993-99 period had the previous highest 5-year spending and volume growth going back to 1984-88.
Construction added 177,000 jobs in the 4 months Nov’17-Feb’18. That’s happened, for any 4-month period, only 5 times since 1984. The last time was 2005-06, during the fastest rate of spending increases since 1984.
Construction jobs pulled back 15k in March, but this follows the strongest month (Feb +65k) in 12 years, so not totally unexpected. I think Mar Construction jobs, (-15k), more likely a pause after Feb (+65k), strongest month in 12 years.
Preliminary data is in for total year 2017 construction spending, 2017 construction starts and 2018 starting backlog. The following forecast is developed using the current data.
2018 Construction Spending Forecast – Mar 2018
A brief note on 2017.
2017 Spending Wrap Up
Total construction spending in 2017 now stands at $1.233 trillion, an increase of 4.0% over 2016.
Residential spending, up 10.5% for the fifth consecutive year above 10% growth, leads all construction spending in 2017 for the seventh consecutive year. Nonresidential Buildings finished the year up 2.3%. Only Non-building Infrastructure did not improve over 2016, down 3.8% for the year. However, Non-building Infrastructure had been at an all-time high for the previous two years.
2017 spending finished below my forecast due to performance in Educational, Office, Power and Highway, four of the five largest markets which together make up half of all nonresidential spending. All came in lower than forecast. However, some of these markets are prone to very large post-annual upward revisions and that has the potential to add to 2017 spending when those revisions are released in July 2018. For instance, in the July 2017 revisions, Power spending for the previous year, 2016, was revised up by 10%.
History shows spending has been revised up 53 times in the last 60 months. I expect to see future revisions smooth out spending in unusually low periods and increase total 2017 spending above this forecast. Both April and July preliminary spending appear statistically too low. The average post-annual total spending revision for the last five years is +2.8%. The post-annual revision to 2016 was only 2.2%. Revisions due for release on July 1, 2018, if even only a +1% revision to 2017, would adjust total 2017 spending up to $1,245 billion. This would slightly alter the 2018 forecast.
2018 Spending Total All Construction
Total All 2018 construction spending is forecast to increase 7.6% to $1.330 trillion.
Nonresidential Buildings spending forecast for 2018, up 9%, will be supported by Manufacturing and Educational. Non-building Infrastructure returns to strong growth of 8%, with potential to hit a new all-time high due to very large projects in Power and Transportation. Residential spending in 2018 slows to growth under 6% after six years all over 10%/year.
Dodge Data 2017 construction starts increased 3% from 2016. However, starts are always revised upward in the following year. I expect revisions will show 2017 starts increased by more than 6% over 2016. Even with that revision, 2017 starts posted the lowest growth since 2011, weighted heavily by the slowdown in residential starts.
Total starting backlog for 2018, currently at an all-time high, has increased on average 10%/year the last three years. 80% of all Nonresidential spending within the year will be generated from projects in starting backlog. Public share of new construction starts are up only 10% in 3 years. But due to long duration job types, 2018 starting backlog is up 30% in the last 3 years.
None of this spending forecast includes any projections for potential work from future infrastructure stimulus.
Current$ vs Constant$
Construction spending reached a new current $ high in 2017 at $1,236 billion. The previous high in current $ was $1,161 in 2006. Spending first surpassed that in 2014 and has been increasing since. But that is in current $, which includes inflation.
Comparing current $ spending to previous year spending does not give any indication if business is increasing. The inflation factor is missing. If spending is increasing at 4%/year in a time when inflation is 6%/year, real volume is declining by 2%.
Although 2018 current $ spending will reach $1,330 billion, after adjusting for 4.5% to 5% inflation, 2018 constant $ volume will increase to only $1,270 billion. When comparing inflation adjusted constant dollars, 2018 spending will still be lower than all years from 1998 through 2007. In 2005 constant $ volume reached a peak at $1,450 billion. At current rates of growth, we would not eclipse the previous high before 2022.
While spending in current $ is 7% higher than the previous high spending, volume is still 14% lower than the previous high volume.

Jobs and Volume
The period 2011-2017 shows both spending and jobs growth at or near record highs.
A spending forecast of 7%+ in 2018, or nearly $100 billion in construction spending, demands a few words on jobs growth. Construction requires about 5000 workers for every added $1 billion in construction volume. Construction jobs have never increased by 500,000 in one year. However, $100 billion in added spending is not the same as $100 billion in volume, and jobs growth is based on volume.
Although spending will increase 7%-8%, construction inflation has been hovering near 4.5% to 5% for the last five years. Real volume growth in 2018 after inflation is expected to be near 3% or $40 billion. That would mean the need, if there are no changes in productivity, is to add only about 200,000 additional workers in 2018, a rate of jobs growth that is well within reach. That is less than the average jobs growth for the last seven years.
Construction added 1,339,000 jobs in the last 5 years, an average of 268,000/year. The only time in history that exceeded jobs growth like that was the period 1993-99 with the highest 5-year growth ever of 1,483,000 jobs. That same 1993-99 period had the previous highest 5-year spending and volume growth going back to 1984-88.
Construction added 185,000 jobs in the last 4 months, Nov17-Feb18. That’s happened, for any 4-month period, only 5 times since 1984. The last time was 2005-06, during the fastest rate of spending increases since 1984.
Total all spending increased 55% since 2010, but there was 30% inflation. Real total volume since 2010 has increased by only 25%. Jobs increased by 30%, 5% in excess of volume growth. But the results are much different for Residential than Nonresidential.
Nonresidential spending increased 43% since 2010, but there was 30% inflation. Real nonresidential volume since 2010 has increased by only 12%. Jobs increased by 27%, 15% in excess of volume growth.
Residential spending increased by 110% since 2010, but after inflation, real residential volume increased by only 57%. Jobs increased by only 37%, 20% short of volume growth.
Residential Buildings Spending
Total Residential spending in 2017 finished at $523 billion, up 10.6% from 2016. This is the 5th consecutive year that residential spending exceeded 10% annual growth. Average spending growth the last six years is 13%/year.
Residential spending in 2017 was 50% single family, 13% multi-family and 37% improvements. In 2011, improvements was 48% of residential spending.
Census does not include flood damage repairs (house shell remains intact but gut renovate) in improvements but does include full flood damaged structure replacements (structure rebuild permit classified as new) in improvements.
Residential spending is more dependent on new starts within the most recent 12 months than on backlog from previous starts. Total starts for the last 6 months are the highest since 2006, but % growth has slowed considerably. New starts in 2017 posted only 2% growth, but I expect that to be revised up to at least 4%. Similar growth of 6%-7% is expected for 2018. Slower growth is now expected after 5 years (2012-2016) of new starts increasing at an average 20%/year.
Residential 2018 spending growth is forecast to increase only 6% after five years over 10%. Total residential spending in 2018 is forecast at $552 billion.
Residential spending will reach a 12-year high in 2018. Residential spending reached its current $ peak of $630 billion in 2005. Current 2018 pending is still 13% below that peak. In constant $, adjusted for inflation, all years from 1998 through 2007 were higher than 2018. In constant $, 2018 spending is still 27% below the 2005 peak.
Residential buildings construction spending in constant $ reached $523 billion in 2017. Previous spending adjusted to equivalent 2017$ shows that all years from 1996 through 2007 had higher volume than 2017. Volume reached a peak $748 billion in 2005. Only the years 2004-2006 had higher spending in current $. The 2005 current $ peak of $630 billion is still 17% higher than 2017, but 2017 volume is still 30% lower than peak volume.
Nonresidential Buildings Spending
Nonresidential Buildings spending in 2017 finished at $419 billion, up only 2.7% from 2016.
2017 spending finished below my forecast due to performance in Educational and Office. Educational starts increased 6%+/year for the last three years, but spending increased only 4%/year the last two years. Office starts increased nearly 30% in 2016, but spending increased only 3% in 2017. I suspect either big upward revisions to 2017 spending or large increases in backlog will boost 2018 spending in these two markets.
Nonresidential Buildings new starts are up 60% in four years. 2018 starting backlog is the highest ever, up 15% from 2017. Nonresidential Buildings 2018 starting backlog is 50% higher than at the start of 2014, the beginning of the current growth cycle.
Starting backlog has increased for five years at an average 10%/year. Spending from starting backlog, up 10% in 2018, increased for five years at an average 9%/year.
For 2018, Educational spending is projected to increase 14%, the best increase since 2007. Starting backlog increased 10%/year for the last three years. Manufacturing posted several very large project starts in 2017. Spending is projected to increase 12% in 2018.
Nonresidential Buildings spending in 2018 is forecast to reach a new high, $459 billion, an increase of 9.5% over 2017, surpassing the previous 2008 high. Educational and Manufacturing make up 55% of the growth.
For the Full Expanded 2018 Construction Spending Forecast – Nonresidential Bldgs
Nonresidential buildings construction spending in constant $ (inflation adjusted $) reached $419 billion in 2017. In 2018 it will reach $439 billion. Constant $ spending shows all years from 1996 through 2010 had higher volume than the 2018 forecast. Volume reached a peak $536 billion in 2000 and went over $500 billion again in 2008. In constant $ 2018 is still 18% below that 2000 peak.
Non-building Infrastructure Spending
Total non-building infrastructure spending in 2017 dropped to $293 billion, down 3.7% from 2016.
Non-building Infrastructure spending, always the most volatile sector, dropped to yearly lows from June through September, the lowest since November 2014. However, this short dip was predicted. Cash flow models of Infrastructure starts from the last several years predicted that dips in monthly spending would be caused by uneven project closeouts from projects that started several years ago, particularly in Power and Highway markets.
Current backlog is at an all-time high and spending is expected to follow the increased cash flows from the elevated backlog. Environmental Public Works (Sewage/Waste disposal down 14%, Water Supply down 9% and Conservation/Dams & Rivers down 7% in 2017) posted the largest declines in 2017 and accentuated the declines in the infrastructure sector. The sector was expected to increase in the last quarter 2017. All three markets posted increases in the 4th quarter, up 8% over the 1st nine months of 2017.
Non-building Infrastructure 2018 starting backlog is the highest ever, up 10%+ each of the last 3 years. Transportation terminals new starts in 2017 jumped 120%. Rail project starts increased more than 100%. Starting backlog for all transportation work is the highest ever, up 100% in the last two years. Transportation spending is projected to increase 20-25%/year for the next two years.
No future growth is included from infrastructure stimulus and yet 2018 spending is projected to increase by 8%.
Non-building Infrastructure will reach a new high for spending in 2018. Spending reached an all-time high in 2015 and stayed within 0.3% of that high for 2016. A 3.5% decline in 2017 was more of a decline than expected, but there may still be upward revisions to the preliminary total.
Non-building Infrastructure spending in 2018 is forecast to reach $319 billion, an increase of 8.6% over 2017.
My forecast for 2018 is predicting every infrastructure market will post gains, but it is the Power and Transportation markets that account for most of the growth in 2018. Transportation new starts in 2017 grew 120% due to massive new air terminal and rail projects. Spending growth in the Power market is not quite so apparent. Combined Power new starts are down for both 2016 and 2017, but the spending gains are coming from projects that started in 2015, a year in which starts were up over 120%.
Adjusted for inflation, spending in 2018 will be nearly equal to the all-time highs reached in 2015 and 2016.
Non-building Infrastructure construction spending in constant $ reached $294 billion in 2017. Recent highs were posted in 2015 and 2016 at $305 billion and $304 billion and 2018 is expected to reach $319 billion. Previous spending adjusted to equivalent 2017$ shows that 2008 and 2009 were both just slightly higher than $300 billion. Constant $ volume reached a peak $313 billion in 2016. Spending in current $ hit new highs in 2015 and 2016. This is the only sector that has current $ and constant $ at or near all-time highs.
Public Infrastructure and Public Institutional
Only 60% of all Non-building Infrastructure spending, about $170 billion, is publicly funded. That public subset of work averages growth of less than $10 billion/year.
Only about 25% of all Nonresidential Buildings spending, about $100 billion, is publicly funded, mostly Educational.
- Infrastructure = $300 billion, 25% of all construction spending.
- Infrastructure is about 60% public, 40% private. In 2005 it was 70% public.
- Public Infrastructure = $170 billion. Private Infrastructure = $130 billion.
- Power and Communications are privately funded infrastructure.
- Nonresidential Buildings is 25% public (mostly institutional), 75% private.
- Educational, Healthcare and Public Safety are Public Nonres Institutional Bldgs
- Public Commercial construction is not included.
- Public Institutional = $100 billion, mostly Education ($70b).
Public Infrastructure + Public Institutional = $270 billion, 23% of total construction spending.
Public Infrastructure + Institutional average growth is $12 billion/year. It has never exceeded $30 billion in growth in a single year.
Public construction is a subset of Nonresidential Buildings and Non-building Infrastructure and about 1% of Residential.
The two largest markets contributing to public spending are Highway/Bridge (32% of total public spending) and Educational (26%), together accounting for nearly 60% of all public construction spending. At #3, Transportation is only about 10% of public spending. Environmental Public Works combined makes up almost 15% of public spending, but that consists of three markets, Sewage/Waste Water, Water Supply and Conservation. Office, Healthcare, Public Safety and Amusement/Recreation each account for about 3%.
2017 spending was down 1%, but has been at or near the all time high for three years.
Total public spending for 2017 finished flat at $284 billion with most major public markets down for the year. By far, the largest Public spending declines in 2017 are Sewer and Waste Disposal which is 7% of public markets, it was down 16% and Highway/Bridge, down only 3.5%, but Highway is 32% of all public spending.
Public spending hit a low in June 2017. It has been increasing since then, Public Educational, in the second half 2017 up 10% from the low point, now at a post recession high. We can expect to see another six months of growth before spending levels off in mid-2018.
Due to long duration job types, 2018 starting backlog is up 30% in the last 3 years. In 2018, 40% of all spending comes from jobs that started before 2017. Leading 2018 growth are Educational (+15%) and Transportation (+35%), with a combined total forecast 20% growth in public spending.
Current levels of backlog and predicted new starts gives a projection that Public Non-building Infrastructure spending will reach an all-time high in 2018 and again in 2019.
Total Public spending in 2018 is forecast to reach $307 billion, an increase of 8% over 2017, the best growth in 10 years.
Educational and Transportation will contribute equally and together account for almost 60% of the Public spending growth in 2018. Transportation new starts in 2017 grew 120% due to massive new air terminal and rail projects. Educational new starts total for the last three months posted the highest quarter in at least seven years. The 2nd highest quarter was also within the last 12 months, so still contributes fully to 2018 spending. 2018 signifies a turn-round in Public spending which has not posted significant growth since the recession.
Public spending is 10%, $30 billion, below 2009 all-time highs, most of the deficit coming from declines in Educational, Sewage/Waste Water and Water Supply. In 2018, Highway and Transportation are at all-time highs.

What data are analysts comparing to show construction jobs shortages?
There are numerous articles circulating in the industry regarding the difficult growth of construction jobs. Some compare the percent growth in jobs to the percent growth in construction spending, often citing that spending has increased far more than jobs.
Well yes, that’s true. BUT…
In the 5 years 2013-2017 jobs increased by 1.3mil or 23%. Spending increased by 45%. The industry, for 5 years, has been saying it is difficult to find skilled workers to fill jobs. And yet total construction jobs added in last 5 yrs = 1.3 million, near all-time high growth.
Only 3 times since 1970 have 5-year jobs totals increased by more than the most recent 5-year period 2013-2017. All of the top jobs growth occurred between 1994-2000.
Only 5 times has 3-year jobs growth exceeded the most recent 3-year period. The period 2004-2006, with the highest 3-year jobs growth, also represents 50-year peak construction volume, although closely rivaled for both jobs growth and peak volume from 1999-2001.
But, comparing jobs growth to spending growth is an invalid comparison. Jobs must be compared to volume. Spending is not volume.
Construction spending includes inflation. Inflation does not support jobs growth. If spending is increasing 6%/year and inflation increases 4%/year, then real construction volume is increasing only 2%/year. Balanced jobs growth would then increase 2%/year.
Spending is measured in current $, always current to the year, which includes inflation from year to year. Volume is reported in constant $, constant to the baseline year, which adjusts for inflation. Jobs should be compared to constant $ volume growth.
For the 5-year period 2013-2017, although spending increased 45%, inflation was near 4%/year for all 5 years. Real construction volume increased only 22%. Jobs, up 23%, just slightly exceeded volume growth during this period.
Update 3-6-19 – Jobs increased 324,000 in 2018, the largest increase since 2006. For the six years 2013-2018 jobs increased 1.6 million up 29%. Spending increased 50%. But after inflation volume increased only 25%. Jobs growth is exceeding volume growth.
I’ve written a series of articles on jobs vs spending/volume, comparing growth back to 2001. Links to the entire series can be found at the bottom of this post. Several things seem apparent from the analysis, among them, potentially hiring to match spending growth and hiring lags spending growth.
A benefit of the series is that it shows, although jobs/volume growth is nearly even, severe jobs imbalances exist within sectors. Nonresidential and Non-building show excess jobs while residential shows a severe jobs deficit.
Nonresidential buildings has had the largest jobs growth in excess of volume growth. This raises the question, are jobs being added in response to spending growth, which is almost 4%/year higher than real volume growth.
Non-building Infrastructure recent growth is similar to Nonres Bldgs, but it started 2011 with a large deficit.
Residential comparisons uncover some hidden factors. In this Residential plot, spending increased by 100% since Jan 1 2011, but after inflation volume increased by only 57%. Jobs lag 20% behind at only 37%.
But, are all residential jobs being counted? Several studies suggest that a large portion of residential construction jobs may be held by uncounted immigrant or day labor. So it’s possible the residential jobs deficit may not be as large as shown.
In addition to uncounted immigrant labor, some labor is mis-classified. Take for example, a high-rise multi-use building with commercial retail, office and residential space. Census definitions of spending classifications break out spending into the 3 market sectors, but the building is built by high-rise contractors (probably normally classified as commercial), not a residential contractor. This then is residential space built using labor classified as non-residential commercial. BLS writes this: “Establishments are classified into industries on the basis of their primary activity… For an establishment engaging in more than one activity, the entire employment of the establishment is included under the industry indicated by the principal activity”
The series of articles explains much more detail including productivity (annual $ put-in-place), jobs/workload balance and hiring patterns.

2018 Spending Forecast
During the period including 2011 through 2017, we had record construction spending, up 50% in 5 years, moderate inflation reaching as high as 4.6% but averaging 3.8%, record construction volume growth (spending minus inflation), up 30% in 5 years and the the 2nd highest rate of jobs growth ever recorded.
Residential spending was up 90% in 5 years, but real residential volume up only 50%. Residential inflation, at 6%/year, was much higher than all construction. Jobs increased only 33%.
Construction added 1,339,000 jobs in the last 5 years. The only time in history that exceeded jobs growth like that was the period 1993-1999 with the highest 5-year growth ever of 1,483,000 jobs. That same 93-99 period had the previous highest spending and volume growth. 2004-2008 would have reached those lofty highs but the residential recession started in 2006 and by 2008 spending had already dropped 50%, offsetting the highest years of nonresidential growth ever posted.
The point made here is the period 2011-2017 shows spending and jobs at or near record growth. Although 2017 slowed, there is no widespread slowdown in volume or jobs growth.
This 2011-2017 plot of Construction Jobs Growth vs Construction Volume Growth seems to show there is no jobs shortage. In fact it shows jobs are growing slightly faster than volume. But that just does not sit well with survey data from contractors complaining of jobs shortages. So how is that explained?
There have been cries from some quarters, including this blog, that the answer lies in declining productivity. There seems to be plenty of workers, but it now takes more workers to do the same job that took fewer in the past. As we will see, that is part of the answer, but doesn’t explain why some contractors need to fill vacant positions. To find data that might answer that question about a jobs shortage we must dig a little deeper.
The total jobs vs volume picture masks what is going on in the three major sectors, Residential, Nonresidential Buildings and Non-Building Infrastructure. A breakout of jobs and volume growth by sector helps identify the imbalances and helps explain construction worker shortages. It shows the residential sector at a jobs deficit.
7 years 2011-2017 – % Jobs growth vs % Volume growth
- Totals All Construction Jobs +31%, Volume +30%
- Nonres Bldgs Jobs +27%, Volume +19%
- Nonbldg Hvy Engr Jobs +21%, Volume +12%
- Residential Jobs +40%, Volume +54%
The totals show jobs and volume almost equal, data that supports the 2011-2017 totals plot above and what we would expect in a balanced market. But severe imbalances show up by sector. Both nonresidential sectors show jobs growth far outpaced volume growth. Residential stands out with a huge deficit, with jobs way below volume growth.
Just looking at 2017 growth shows the most recent imbalances.
2017 % jobs growth vs % volume growth
- Totals All Construction Jobs +3.4% Volume -0.8%
- Nonres Bldgs Jobs +3.3% Volume -1.6%
- Nonbldg Hvy Engr Jobs +1.7% Volume -6.0%
- Residential Jobs +3.5% Volume +4.2%
Census recently released initial construction spending for 2017, totaling $1.230 trillion, up only 3.8% from 2016. What is somewhat disconcerting is that 2017 construction spending initial reports growth of 3.8% do not even match the total inflation growth of 4.6% for 2017, indicating a -0.8% volume decline. However, as does always occur, I’m expecting upward revisions (estimated +2%) to 2017$ construction spending on 7-1-18. If we don’t get an upward revision, then 2017 will go down as the largest productivity decline since recession. Even if we do get +2% upward revision to 2017$ spending, 2017 volume would be revised up to +1.2% and jobs growth will still exceed volume growth.
Let’s look a little deeper at the data within the sectors. Each chart is set to zero at Jan 2011 so we can see the change from that point, the low point of the recession, until today. At the bottom of each chart is shown a Balance at start. That represents the cumulative surplus or deficit of jobs growth compared to volume growth for the previous 10 years prior to Jan 2011. If there are no changes in productivity, or no surplus or deficit to counteract, then jobs should grow at the same pace as volume.
There are slight differences between the data in the three sector charts and the total construction chart. The sector charts use annual avg data and the totals chart uses actual monthly data.
Nonresidential Buildings and Non-building Infrastructure, over seven years and the most recent three years, show jobs increasing far more rapidly than volume. Nonresidential Buildings started 2011 with a surplus of jobs after the recession, but Infrastructure started 2011 with a substantial deficit of jobs. Only in this last year did Infrastructure jobs reach long-term balance with work volume.
Nonresidential Buildings started 2011 with a 13% surplus of jobs and more than doubled it in the seven years following. I’ve suggested before it could be that a part of this surplus is due to companies hiring to meet revenue growth, and not inflation adjusted volume. Although nonresidential spending actually increased 43%, volume since 2010 has increased only 12%. Since 2010 there has been 30% nonresidential buildings inflation, which adds zero to volume growth and zero need for new jobs. A 43% increase in spending could lead companies to erroneously act to staff up to meet spending, or revenue, more than needed for the 12% volume increase.
This plot for residential work shows from 2011 to the end of 2017, we’ve experienced a 20% growth deficit in jobs. How many residential jobs does this 20% growth deficit represent? From Jan 2011 through Dec 2017, residential jobs increased from approximately 2,000,000 to 2,700,000. So the base on which the % growth increased over that time is calculated on 2,000,000. An additional 20% growth would be a maximum of 400,000 more jobs needed to offset the seven year deficit. But what about the imbalances that existed when we started the period?
During the residential recession from just 2005 through 2010, residential volume declined by 55%, but jobs were reduced by only 38%. For the entire period 2001-2010, total volume of work declined by 14% more than jobs were reduced. Some of the surplus jobs get absorbed into workforce productivity losses and some remain available to increase workload. It’s impossible to tell how much of that labor force would be available to absorb future work, so for purposes of this analysis an estimate of at least 5% seems not unreasonable. That would mean for 2011-2017, instead of a need for an additional 20% more jobs, the need could be reduced by 5% or 100,000 jobs.
This analysis shows a current deficit of 300,000 to 400,000 residential construction jobs. While it does also show nonresidential buildings jobs far exceed the workload and there are more than enough surplus jobs to offset the residential deficit, there would be several questions of how transferable jobs might be between sectors.
- Are there highly technical specialty jobs in Nonresidential Buildings that would not be transferable to Residential?
- What is the incidence of specialty workers engaging in work across sectors? i.e., job is counted in one sector but working in another sector.
- What has been the impact of losing immigrants from the construction workforce?
- Is the ratio of immigrant workers in Residential much higher than Nonresidential?
- Is the pay more attractive in Nonresidential construction?
- What, if any, percentage of the Residential workforce is not being counted? Day labor?
One thing is known for certain, high-rise multifamily residential buildings may often be built by a firm that is classified primarily as a nonresidential commercial builder. Therefore, some jobs that are counted as nonresidential are really residential jobs.
I think most of these would have a more negative impact on Residential jobs. However, there is some possibility that the overall deficit may not be quite as high as available data show (points 2 and 6). And there is always the possibility that we’ve crossed a threshold that has led to new gains in productivity, although to some extent, the stark differences between Residential and Nonresidential Buildings data might counter that proposition.
These two following report references both document that there is a large unaccounted for shadow workforce in construction. This workforce is probably mostly residential.
and these more recent reports adds volumes of data on immigrant labor
Unemployment and productivity includes only jobs counted in the official U.S. Census Bureau of Labor Statistics (BLS) jobs report. Both these reports document a large, unaccounted for shadow workforce in construction. By some accounts, 40% or more of the construction workforce in California and Texas are immigrant workers. Immigrants may comprise between 14% and 22% of the total construction workforce. It is not clear how many within that total may or may not be included in the U.S. Census BLS jobs report. However, the totals are significant enough that they would alter some of the results commonly reported.
The best way to see the implications that the available data do show is to look at productivity. The simplest presentation of productivity measures the total volume of work completed divided by the number of workers needed to put the volume of work in place, or $Put-in-Place per worker. In this case, $ spending is adjusted for inflation to get a measure of constant $ volume, and jobs are adjusted for hours worked.
As the Residential jobs deficit increases vs workload, this plot shows that $PIP is increasing. That makes sense. The workload continues to increase and the jobs growth is lagging, so the $PIP per worker goes up. For Nonresidential Buildings, the rate of hiring is exceeding the rate of new volume and therefore the $PIP is declining.
In boom times, residential construction adds between 150,000 and 170,000 jobs per year and has only twice since 1993 added 200,000 jobs per year. In the most recent several years expansion, residential has reached a high of 156,000 jobs in one year but has averaged 130,000 per year over 5 years. So it’s pretty unlikely that we are about to start adding residential construction jobs at a continuous rate of 200,000+ jobs per year.
If residential jobs growth were to increase by 50,000 jobs per year over and above current average growth, it would take 6 to 8 years to wipe out the jobs deficit in residential construction.
This problem is not going away anytime soon.
