Construction added 22,000 jobs on net in August, and the industry unemployment rate fell to 3.1%. That’s an all-time low, down a tenth of a point from August 2025, against an all-industry rate of 4.1%.
Year over year, construction employment is up 120,000 jobs, or 1.5%. That’s the fastest annual pace since February 2025 and the sixth consecutive month of gains, according to Associated Builders and Contractors’ read of the Bureau of Labor Statistics data released Friday.
The gains are concentrated, not broad
Nonresidential construction added 10,400 positions, and the composition matters more than the total. Nonresidential specialty trade contractors picked up 7,800 and heavy and civil engineering added 4,400. Nonresidential building lost 1,800.
So the segment that puts up the shell of a building shed workers while the segments that run conduit, pipe, and civil works hired. ABC chief economist Anirban Basu ties that directly to data center construction, and notes the growth happened despite a shrinking homebuilding segment. His attribution is interpretation rather than something the establishment survey measures, but the pattern is consistent with where the money has gone: electrical, mechanical and site work at hyperscale campuses absorbs trades faster than it absorbs building contractors.
A record-low unemployment rate with a shrinking segment underneath
Those two facts sit together uncomfortably, and both are true. Residential construction is contracting. The industry unemployment rate is the lowest ever recorded. What that combination usually means is that workers leaving one segment are getting absorbed by another fast enough that they never show up as unemployed, which is a healthier outcome than the alternative but also a sign of how tight the specialty trades have gotten.
It also caps how fast the nonresidential build-out can go. You cannot hire your way through a 3.1% unemployment rate. Firms competing for the same electricians on the same data center campuses are bidding wages, not recruiting new entrants, and the training pipelines that would change that take three to five years to produce a journeyman.
Read the revisions
Total nonfarm payrolls rose 162,000, well above the prior 12-month average of about 31,000 a month, and June and July were revised up by a combined 55,000. July went from a reported loss of 23,000 to a gain of 21,000, which is a 44,000-job swing in a single revision.
That’s the caution. These are preliminary establishment-survey estimates, seasonally adjusted, with two more revisions still to come. The construction unemployment rate isn’t seasonally adjusted at all and moves around. The all-time-low framing is ABC’s, and it will hold or it won’t once the benchmark revision lands.
