According to the Associated General Contractors of America, every state but one, North Dakota, lost construction jobs in October.

“A shockingly large portion of the construction industry’s workforce has simply evaporated,” said Ken Simonson, chief economist for the association.

He added that the national construction unemployment rate of 18.7 percent was the highest of any sector in October and the industry accounted for one-fifth of all job losses in the past year, even though construction only employs one out of 20 workers.

The five biggest percentage losses in construction employment over the year occurred in Nevada (26.9 percent, or 30,200 jobs), Arizona (24.2 percent, or 42,600 jobs), Tennessee (22.3 percent, or 29,300 jobs), Kentucky (20.8 percent, or 17,600 jobs) and Connecticut (19.3 percent or 12,500 jobs).

According to the AGC, locally:

Delaware has lost -11.6% of its construction jobs from one year ago and ranks 16th in the nation for loss of construction jobs.

New Jersey has lost -13.4% of its construction jobs from one year ago and ranks 24th in the nation for loss of construction jobs.
