Construction employment increased in 34 states between November 2015 and November 2016, according to analysis of Labor Department data by the Associated General Contractors of America (AGC). Twenty-nine states and the District of Columbia added jobs in the segment during the past month.

“Most of the construction employment gains are coming as firms in many states work to keep pace with growing demand,” says Ken Simonson, AGC chief economist. “In other states, however, construction employment is being held back by either a lack of work where demand is weak or a lack of workers where demand exceeds the pool of qualified workers.”

California added the most construction jobs (35,100 jobs, 4.7 percent) during the past year. Other states adding a high number of new construction jobs for the past 12 months include Florida (23,200 jobs, 5.3 percent), Washington (16,500 jobs, 9.4 percent) and Colorado (12,800 jobs, 8.3 percent). Nevada (11.7 percent, 8,400 jobs) added the highest percentage of new construction jobs during the past year, followed by Iowa (10.2 percent, 8,300 jobs), Washington and Oregon (8.4 percent, 7,000 jobs).

Fourteen states shed construction jobs between November 2015 and November 2016 while construction employment was unchanged for the year in D.C. and two states. New York lost the highest number of construction jobs (-6,400 jobs, -1.7 percent), followed by Kansas (-3,600 jobs, -5.9 percent), Alabama (-3,600 jobs, -4.4 percent), Connecticut (-2,200 jobs, -3.8 percent) and Kentucky (-2,200 jobs, -2.9 percent).

California added the most construction jobs between October and November (3,900 jobs, 0.5 percent). Other states adding a high number of construction jobs for the month include Ohio (3,600 jobs, 1.7 percent), Minnesota (3,400 jobs, 2.9 percent) and Missouri (3,000 jobs, 2.5 percent). Montana (8.5 percent, 2,100 jobs) added the highest percentage of construction jobs during the past month, followed by West Virginia (5.2 percent, 1,600 jobs), Maine (4.5 percent, 1,100 jobs), Alaska (4.3 percent, 700 jobs) and Minnesota.

Connecticut lost the highest percentage of construction jobs between October and November, followed by Arizona, Vermont (-1.9 percent, -300 jobs), Alabama (-1.3 percent, -1,000 jobs), Oklahoma (-1.2 percent, -1,000 jobs) and Indiana (-1.2 percent, -1,600 jobs).
