Construction firms added jobs in 36 states between August 2013 and August 2014, while construction employment increased in 28 states between July and August, according to a recent analysis of Labor Department data by the Associated General Contractors of America. Association officials noted that construction activity continues to spread even as employment gains remain uneven by month and state.

“The number of states with increases in construction employment over the last 12 months moderated in August but remained strongly positive as construction activity continues to spread across most of the nation,” said Ken Simonson, the association’s chief economist. “While most states remain far below pre-recession peak employment levels, more states are approaching previous highs and more contractors have been reporting difficulty in hiring qualified workers. These trends are likely to intensify if the recovery in construction continues.”

Florida added more new construction jobs (43,500 jobs, 11.8%) between August 2013 and August 2014. Other states adding a high number of new construction jobs for the past 12 months included California (35,600 jobs, 5.6%), Texas (27,700 jobs, 4.5%), Illinois (11,100 jobs, 5.8%) and Pennsylvania (10,800 jobs, 4.8%). Nevada (12.8%, 7,200 jobs) added the highest percentage of new construction jobs during the past year, followed by Florida, Utah (11.4%, 8,400 jobs), Delaware (10.7%, 2,100 jobs) and North Dakota (9.4%, 3,200 jobs).

New Jersey lost the highest percentage and total, (-8.1%, -11,300 jobs). Other states that lost a high percentage of jobs include Mississippi (-7.1%, -3,700 jobs), West Virginia (-5.3%, -1,800 jobs) and Arizona (-4.4%, -5,400 jobs).
