Construction firms added jobs in 39 states in July on a year-over-over basis, according to an analysis of U.S. Department of Labor data released today by the Associated General Contractors of America.

Nevada posted the largest year-over-year percentage increase in construction employment in July at 13.4 percent. However, Florida led in terms of total number of jobs added with 40,600 jobs added year over year in the Sunshine State.

“The overall trend in construction employment has been very consistent in 2014, with more than three-fourths of states adding jobs each month on a year-over-year basis,” said Ken Simonson, the association’s chief economist. “However, growing numbers of contractors say they are having trouble finding skilled workers or subcontractors that can supply such workers.”
