Two-thirds of U.S. metropolitan areas saw growth in construction jobs from February 2015 to February 2016, according to analysis of federal employment data by the Associated General Contractors of America (AGC).

Employment in the sector increased in 234 out of 358 metro areas, was unchanged in 52 and declined in 72 during that span.

“Many parts of the country continue to see robust construction job growth as demand for projects rises,” says Ken Simonson, AGC’s chief economist. “Construction employment in many energy producing areas, however, appears to be suffering as lower prices for products like coal, oil and natural gas cuts into demand for construction services.”

Anaheim-Santa Ana-Irvine, Calif. added the most construction jobs during the past year (12,500 jobs, 15 percent), followed by New York, N.Y. (11,900 jobs, 9 percent), Orange-Rockland-Westchester, N.Y. (7,800 jobs, 23 percent) and Orlando-Kissimmee-Sanford (7,500 jobs, 13 percent). The largest percentage gains occurred in Monroe, Mich. (60 percent, 1,200 jobs), El Centro, Calif. (48 percent, 1,000 jobs) and Weirton-Steubenville, W.V.-Ohio (29 percent, 400 jobs).

The largest job losses from February 2015 to February 2016 were in Fort Worth-Arlington, Texas (-4,100 jobs, -6 percent), Cleveland-Elyria, Ohio (-3,200 jobs, -10 percent), Midland, Texas (-3,200 jobs, -12 percent) and Odessa, Texas (-3,000 jobs, -15 percent). The largest percentage declines for the past year were in Bloomington, Ill. (-16 percent, -400 jobs), Odessa, Greeley, Colo. (-14 percent, -2,600 jobs), Decatur, Ill. (-13 percent, -400 jobs) and Laredo, Texas (-13 percent, -600 jobs).

“Considering the strong demand for construction many parts of the country are experiencing, it is tempting to imagine how many more people firms would have hired had they been able to find more qualified workers,” says Stephen E. Sandherr, AGC’s chief executive officer. “Assuming demand for construction continues to grow, most firms will have an even harder time finding, recruiting and preparing new workers.”
