Three-quarters of U.S. states added construction jobs from July 2016 to July 2017, yet only half the states increased employment in the sector between June and July, according to an analysis of Labor Department data by the Associated General Contractors of America (AGC).

“Despite growing private-sector demand, it appears that construction employment in some parts of the country is being brought down by declining public-sector investments,” says AGC chief economist Ken Simonson. “Some of these declines will be offset thanks to recently enacted state infrastructure funding increases, but stagnant federal investments are not helping.”

California added the most construction jobs (51,000 jobs, 6.6 percent) during the past year. Other states adding a high number of new construction jobs for the past 12 months include Florida (35,800 jobs, 7.5 percent); Louisiana (13,900 jobs, 9.8 percent); Oregon (11,900 jobs, 13.2 percent) and Texas (10,400 jobs, 1.5 percent). Oregon added the highest percentage of new construction jobs during the past year, followed by Nevada (12.8 percent, 9,700 jobs); Rhode Island (12.7 percent, 2,300 jobs) and New Hampshire (11.8 percent, 3,000 jobs).

Thirteen states and the District of Columbia shed construction jobs between July 2016 and July 2017 while construction employment was unchanged in North Dakota. Iowa lost the highest number of construction jobs (-4,400 jobs, -5.4 percent), followed by Illinois (-4,300 jobs, -2.0 percent) and North Carolina (-2,500 jobs, -1.2 percent). South Dakota lost the highest percentage for the year (-5.6 percent, -1,400 jobs) followed by Iowa and Mississippi (-3.9 percent, -1,700 jobs).

Among the 25 states that added construction jobs between June and July, California added more than any other state (8,200 jobs, 1.0 percent), followed by Florida (5,500 jobs, 1.1 percent). Oklahoma (3.4 percent, 2,700 jobs) added the highest percentage of construction jobs for the month, followed by Maine (2.4 percent, 700 jobs); and Missouri (2.3 percent, 2,700 jobs).

Twenty-four states and D.C. lost construction jobs between June and July while construction employment was unchanged in Rhode Island. Georgia (-3,200 jobs, -1.8 percent) lost the most construction jobs for the month. Other states losing a high number of construction jobs include Pennsylvania (-2,900 jobs, -1.2 percent); North Carolina (-2,400 jobs, -1.2 percent) and Iowa (-2,300 jobs, -2.9 percent). New Mexico (-3.9 percent, -1,800 jobs) lost the highest percentage of construction jobs during the past month, followed by Vermont (-3.3 percent, -500 jobs); Wyoming (-2.9 percent, -600 jobs) and Iowa.
