Construction employment declined in 165 out of 337 metropolitan areas between July 2011 and July 2012, increased in 123 and was stagnant in 49, according to a new analysis of federal employment data recently released by the Associated General Contractors of America. Association officials said that the new data comes out as many metro areas continue to struggle with constricting public-sector budgets and uneven private-sector growth.

“Construction employment is healthy in the handful of areas where private-sector demand is on the rebound,” said Ken Simonson, the association’s chief economist. “However, construction employment in most metro areas is suffering from the effects of tepid private-sector demand and shrinking public-sector construction budgets.”

The largest job losses were in Chicago-Joliet-Naperville, Ill. (-6,500 jobs, -5%); followed by Tampa-St. Petersburg-Clearwater, Fla. (-6,100 jobs, -12%); Nassau-Suffolk, N.Y. (-5,100 jobs, -8%); New Orleans-Metairie-Kenner, La. (-5,000 jobs, -16%) and Virginia Beach-Norfolk-Newport News, Va.-N.C. (-4,400 jobs, -12%).

Springfield, Mass.-Conn. (-28%, -3,000 jobs) lost the highest percentage. Other areas experiencing large percentage declines in construction employment included Anchorage, Alaska (-23%, -2,500 jobs); Detroit-Livonia-Dearborn, Mich. (-17%, -3,600 jobs) and Jackson, Miss. (-16%, -1,800 jobs).

Bakersfield-Delano, Calif. added the highest percentage of new construction jobs (23%, 3,200 jobs) followed by Yuba City, Calif. (18%, 300 jobs); El Centro, Calif. (15%, 200 jobs) and Pascagoula, Miss. (15%, 700 jobs). Los Angeles-Long Beach-Glendale, Calif. (7,700 jobs, 7%) added the most jobs. Other areas adding a large number of jobs included Fort Worth-Arlington, Texas (6,200 jobs, 11%); Phoenix-Mesa-Glendale, Ariz. (5,600 jobs, 7%); Indianapolis-Carmel, Ind.
