November not seasonally adjusted (NSA) construction unemployment rates were down in 38 states and the U.S. as a whole year-over-year, according to analysis by Associated Builders and Contractors (ABC). The national rate of 5.7 percent was down 0.5 percent from a year ago and unchanged from October, data from the Bureau of Labor Statistics (BLS) shows.

This was the lowest national NSA November construction unemployment rate on record, matching the 5.7-percent rate in November 2005 and November 2000, according to ABC.

“From October 2010 through November 2016, the NSA national construction unemployment rate has fallen from the previous year’s reading every month,” says Dr. Bernard M. Markstein, president and chief economist of Markstein Advisors, who conducted the analysis for ABC. “These industry-specific unemployment rates are not seasonally adjusted, so it is best to look at the national and state rates on a year-over-year basis. The continued decline on a year-over-year basis in the unemployment rate nationally and in the majority of state rates is an indication of the health of the construction job market and its recovery from the deep recession it experienced. The demand for skilled construction workers remains especially strong leading into 2017.”

The states with the lowest estimated NSA construction unemployment rates in order from lowest rate to highest were Massachusetts, Utah, New Hampshire, Colorado and Iowa.

The five states with the highest NSA construction unemployment rates in order from lowest to highest rates were Pennsylvania, Illinois, Alabama, New Mexico and Alaska.
