Construction firms added jobs in 38 states and the District of Columbia between November 2013 and November 2014 while construction employment increased in 26 states and D.C. between October and November, according to a recent analysis of Labor Department data by the Associated General Contractors of America (AGC).

“Construction job growth remains positive overall but volatile,” says Ken Simonson, the chief economist for AGC. “Although more than three-quarters of states have added construction jobs from year-earlier levels throughout 2014, the list of states with gains keeps changing. Only North Dakota, Louisiana and Oklahoma have exceeded their pre-recession peaks for construction employment this year, while most states are still at least 10 percent below previous highs.”

Texas added more new construction jobs (47,300 jobs, 7.7 percent) between November 2013 and November 2014 than any other state. Other states adding a high number of new construction jobs for the past 12 months included California (40,800 jobs, 6.3 percent), Florida (34,900 jobs, 9.1 percent), Washington (12,800 jobs, 8.6 percent) and Illinois (12,000 jobs, 6.2 percent). North Dakota (16.2 percent, 5,300 jobs) added the highest percentage of new construction jobs during the past year, followed by Utah (10.1 percent, 7,600 jobs), Florida, Washington and Arkansas (8.4 percent, 3,900 jobs).

Twelve states lost construction jobs during the past twelve months, with West Virginia losing the highest percentage (-11.3 percent, -3,800 jobs). Other states that lost a high percentage of jobs include Mississippi (-7.9 percent, -4,200 jobs), New Jersey (-4.5 percent, -6,200 jobs) and Nebraska (-4.1 percent, -1,900 jobs). New Jersey shed the most construction jobs. Other states that lost the most construction jobs between November 2013 and November 2014 include Arizona (-4,600 jobs, -3.7 percent), Mississippi, West Virginia and Kentucky (-2,400 jobs, -3.6 percent).
