The construction industry posted healthy gains in 38 states in November, the Associated General Contractors of America says.

Citing federal data, it says only six states have not posted construction jobs gains in the past year. However, the numbers could be even better, the association says.

"In nearly every state, contractors are busier now than a year ago," said Ken Simonson, chief economist for the association. "Employment is up, but the industry would be expanding even more rapidly if contractors could find enough qualified workers."
