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 apply inflation 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 (through Nov) increased only +48k in the last 7 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.
Caution is advised if putting emphasis on construction JOLTS, which has been climbing to new highs. From mid-2006 to mid-2007, JOLTS reached near the then all-time high. But construction volume, starting in mid-2006, was already on the downward slope. Volume peaked in early 2006 and fell 10% by mid-2007. Construction did not begin shedding jobs until late 2006, but mid-2007, job losses were well underway. Within 12 months, more than 500,000 jobs were gone. Within 18 months, construction jobs were down 1.5 million.
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.
8-15-19 edits – added plots
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.

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.
Construction Overtime – A Common Miscalculation
You never get full production out of all overtime hours worked. A common miscalculation when applying overtime overlooks productivity losses.
Let’s say we have a project that has 100 manweeks of productive work (100mw x 40hrs = 4000 manhours) remaining on the schedule to completion, but that we absolutely must finish the job is less time. Also, let’s say we modify the work week from 5 days 8 hours = 40 hours/wk to Overtime (OT) 6 days 10 hours = 60 hours/wk. A simple calculation indicates that if we add 50% more hours per week (60hrs vs 40hrs), we could finish the job in 1/3 less time.
- Original plan = 4000 manhours / 40 hrs/week/man = 100 manweeks
- Revised plan = 4000 manhours / 60 hrs/week/man = 67 OT manweeks
- Time saved = (100–67)/100 =33/100= 33% time saved, 33 mwks saved
- Cost added would be +20%. See example of cost calculation below.
But, unfortunately, that would not be correct. That would have to assume no OT productivity losses. You won’t get 60 productive hours out of a man in a 6-10s 60-hour OT workweek. You will get only 50 productive hours.
Productivity loss graphic from Applied Cost Engineering, Clark and Lorenzoni, Marcel Dekker, Inc., 1985.
Yes, you still pay for all hours and the man is still on the job for 60 hours, but work progress slows as workers are kept on the job for longer periods. So how much time would be saved on the schedule?
Revised plan productivity 4000 manhours work / 50 productive hrs per week per man = 80 OT manweeks to completion.
Time saved = (100 – 80) / 100 = 20/100 = 20% time reduction or 20 mwks saved, not 33.
What did we get from this application of overtime compared to the original?
- 20 mnwks LESS of normal 40hrs =20×40= 800hrs less at normal 1x rate
- 80 mnwks at 20hrs/wk at OT, 1.5x rate =80×20= 1600hrs more at 1.5x rate
- Net cost 1600 x 1.5 – 800 x 1 = 1600 equivalent extra cost hrs over base 4000.
- Time saved (100-80)/100 = 20%
- Cost increased 1600/4000 = 40%
This simple example shows the full hourly time savings is not realized due to lost productivity plus many of the hours worked are at a higher cost. Though the initial basic OT estimate forecast 33% time saved at 20% extra cost, that scenario actually saved only 20% time and added 40% cost, double the initial budget.
If this was initially a 30 month project, with approximately 35% of the cost in labor, then overtime saved 6 months time, but added 15% inflation to the total cost.
There’s a significant difference in the original un-adjusted OT estimate of time/cost versus the OT time/cost analysis for nonproductive hours. That would be a serious mistake in estimating and could have serious cost implications against the budget.
This will vary with the OT scenario selected or any other data set used, but generally the more days and longer hours worked, the higher the extra cost ratio. Of course, a better way to accomplish a tightened schedule might be to add a second shift rather than work men longer hours. However, in times of restricted labor supply that might not be feasible.
See this blog post for OT productivity loss rates Overtime Isn’t Always What It Seems – Lost Productivity Construction
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.

For some hypotheses as to why nonresidential imbalances continue to increase see Construction Spending May 2017 – Behind The Headlines
The last time construction jobs and workload were balanced was 2005. From 2006 through early 2011, workload dropped 15% greater than the decline in jobs. In other words, compared to 2005, contractors started the post-recession period in 2011 with 15% less workload on hand compared to the number of workers kept on staff and that resulted in the period 2006-2011 posting the largest productivity decline ever recorded.
For a discussion on data plotted 2001 to 2011, see this post Jobs vs Construction Volume – Imbalances. In the 2001-2011 plot above, jobs and workload are set to zero baseline in Jan 2001. This shows all of 2001 through 2004 that jobs/workload was balanced. The gap between the red and the blue lines above is the variance from zero change in Jobs/Workload balance. By Jan 2011 there was a 15% workload deficit.
The 1st quarter of 2011 was a dramatic turning point. Both jobs and work volume began to increase. To visualize the variance since Jan 2011, the following plot resets jobs and workload to zero baseline in Jan 2011.
From Jan 2011 to Jun 2015, construction volume increased 24% in 4 1/2 years. Staffing output increased 19% in the same period. Contractors may still feel the effects from not being able to grow staff at that same pace as volume during that period. However, we did see the larger work volume increases make up 5% of the 15% workload deficit from the previous period 2006-2011, but it loses sight of the fact that after almost five years we had not recouped the entire lost work output from all the other 10% staff imbalance that still remained.
Work output is defined as jobs x hours worked. Construction volume is defined as spending minus inflation.
From Jul 2015 to Oct 2017, volume increased just over 1% but jobs output grew by almost 7%. During that two year period, new jobs created plus the change in hours worked by the entire workforce grew 6% more than workload. Jobs increased greater than construction volume increased. The plot shows most of that variance occurred in 2015.
Shifting the time periods slightly gives another impression of the data, overall not much different. In discussions about Construction skilled labor shortages, it’s important to understand, both construction spending and volume are at record growth levels and jobs, since recession, and in last 3 yrs, have matched volume growth.
Overall, in the seven-year post-recession period Jan 2011 to Oct 2017, volume increased 25% and jobs output increased 26%. There seems very little room to be calling this a jobs shortage. Of course, this does not address skills.
So here we are most of the way through 2017 and if we look back at the last 11 years, not only are jobs once again increasing faster than workload, but also in total since 2005 we still have 14% staff that would need to be absorbed by new workload to return to the previous jobs/workload productivity balance.
Maybe it’s time we stop calling this a jobs shortage and start referring to it as a productivity challenge that needs to be turned around.

From January 2001 to June 2017, jobs growth exceeded construction volume growth by 13%. The attached plots show the imbalances in growth.
Jobs growth is # of jobs x hours worked.
Volume is construction spending adjusted for inflation, or constant $.
Sometimes rapid spending growth is accompanied by higher than average inflation. This occurred in the 1990’s and again in 2005-2006. While spending seems to indicate rapid growth, much of the growth in cost is inflation and volume growth can be significantly lower, even sometimes negative, as occurred in 2005-2006. However, jobs growth during these rapid spending growth periods appears to track much more in line with spending growth. This leads to over-hiring and a loss of productivity occurs.
There are two distinct periods when jobs growth advanced more rapidly than real construction volume, 2005-2006 and mid-2015 to mid-2017. In the eight year period in between, either jobs fell faster or, after January 2011, volume increased faster. If spending growth is used to compare, then jobs growth falls far short of construction spending. But, due to inflation, spending is not the correct parameter to compare to jobs. Jobs must be compared to volume. Since 2001, the imbalance shows jobs growth has exceeded volume growth.
2001 through mid-year 2017, jobs exceeded volume growth by 13%.
2001-2004 jobs and volume growth were nearly equal.
2005-2006 jobs growth exceeded volume growth by 20%. During this period, construction spending and volume reached a peak. From late 2004 into early 2006, we experienced 20% growth in spending, the most rapid growth period on record. But that was also the period of the most rapid inflation growth on record. Residential volume peaked in early 2006 but then dropped 20% by the end of 2006. Nonresidential spending was increasing, but almost all of the growth was inflation. Nonresidential volume remained flat through 2006. Inflation was greater than spending growth, so volume declined. Although volume declined, hiring continued and jobs increased by 15%.
2007-2010 volume exceeded jobs growth by 4%. Spending decreased by 30%. Both volume and jobs were in steep decline. More jobs declined than volume, however, this period started with nearly 20% excess jobs. For January 2010 to January 2011, jobs bounced around near bottom, but volume dropped 8% more. 2010 ended with an excess of 15% jobs. January 2011 was the low-point for jobs.
2011-June 2015 volume exceeded jobs growth by 10%. Spending increased by almost 40% and inflation was relatively low at only 3%/yr. This period helped absorb more than half of the excess jobs that were created in 2005-2006 and remained after 2010. By mid-2015, jobs exceeded volume by only 7%.
June 2015-June 2017 jobs growth exceeded volume by 7%. Spending increased by 7%, but inflation was 7% over the same period. Although volume was up and down, over this two-year period through June 2017 we posted zero growth in volume. All of the increase in spending was inflation. Jobs increased 7% in two years.
For the last 5 years, 2012-2016, jobs averaged 4.5%/yr. growth Construction spending averaged 8.5%/yr. growth. Inflation, currently hovering around 4.5%, averaged about 3.5%/yr. during this period. So real volume growth was only 4% to 5%. In the first few years of the recovery, 2011-2014, the gap narrowed and volume improved over jobs, but for the last two years, jobs have been increasing faster than volume.
I do expect spending to continue at a 6% to 7% growth rate at least through 2018. But also, I expect inflation at 4% to 4.5%. If the spending forecast holds, and if jobs growth comes into balance, then that would indicate only a 2% to 3% jobs growth rate from now through 2018.

A few bullets from this presentation
- Construction Starts is not construction spending
- Cash flow = Spending = Revenue
- Revenue is not Volume of work
- Spending minus inflation = Volume
- Understand what’s in an Index to avoid misguided inflation adjustments
- We can’t ignore productivity
- Spending activity has just as much influence on inflation as labor and material cost.

Jobs growth slowed in the last two months adding only 6,000 construction jobs since February. However, a longer term look at jobs x hours worked vs volume growth gives better information.
In the following plot Jobs (red line) = # of jobs x hours worked and Construction Volume (blue line) = construction spending in constant $ (adjusted for inflation). Unless we make these two adjustments we cannot compare jobs to construction spending and get any meaningful analysis from the data.
I’ve written about this in-depth in these two articles.
You can see in the plot above from Jan 2011 to Mar 2013 both jobs growth and volume growth balanced. Then again by August 2014 jobs growth caught up to volume growth. It was the period from Aug 2014 to Jul 2015 when volume took off and climbed much faster than jobs growth. But then, since July 2015, jobs have been increasing faster than construction volume growth.
In a plot of this information back to 2005, it would show that by the end of 2010 there were already excess jobs. That is discussed in the attached articles. During the expansion, firms hired more employees than real work volume could support, then during the recession, firms held onto far more staff than was required to perform the available declining work volumes. So the chart above would start 2011 with an excess of jobs and really we needed to see work volume increase faster than jobs starting in 2011.
Long term, having started 2011 with not enough volume to support the remaining staff, we see two periods of growth in which jobs and volume were balanced, only one period where volume exceeded jobs growth and then this latest period, for the last 21 months, in which jobs are growing faster than volume.
There are many reports of job shortages and they appear to be genuinely accurate assessments, primarily regarding some very specific skilled labor positions. However, long term jobs vs volume data shows there is far more in play than not enough workers to hire. In fact, for the last 21 months, hiring has exceeded workload and that simply does not indicate an overall worker shortage.
I’ve been saying for a long time the data doesn’t show a construction jobs shortage.
In total, construction jobs have been increasing faster than construction volume (spending minus inflation). But, to get a better picture we need to look at jobs vs volume by sector, Residential and Nonresidential. Then we need to look at history.
Since 2009, RESIDENTIAL volume has increased 49%, jobs increased 22%. This is partly explained by absorption of excess staff retained during recession.
From 2006 to 2009 volume decreased 53% but jobs decreased only 36%, leaving a significant amount of excess jobs.
It looks like from 2009 to 2016 there has not been enough jobs growth to support the volume growth, BUT…
Residential net changes just since 2006, volume is down 29% while jobs are down 22%. We are not nearly back to pre-recession productivity.
Since 2009, NONRESIDENTIAL BUILDINGS volume is down by 10% but jobs are up 13%. By no means, if we look at just these 7 years, does this look like a jobs shortage.
Even previous years imbalance would not account for a need to add that many jobs. From 2006 to 2009 volume increased 2% but jobs decreased 15%. In a previous report Is There a Construction Jobs Shortage? I explained why this may occur following a prior top-heavy jobs expansion during a period of high inflation.
Nonresidential net changes just since 2006, volume is down 8% but jobs are down only 3%. Again, we are not nearly back to pre-recession productivity.
For both residential and nonresidential buildings, comparing post-recession growth to pre-recession 1996-2006 $ Put-In-Place per Job, productivity is down 21%, or we currently have 100/(100-21) = 27% more jobs now than it took before to get the same amount of work done.
If the current construction expansion period is viewed as having a jobs shortage, that claim demands that we must accept, since pre-recession, productivity has declined by 21% and the reason there is now a jobs shortage is that it takes 27% more jobs to put in place construction than it did on average from 1996 to 2006.
In my opinion, that’s a harder pill to swallow than a jobs shortage.
