Construction’s February unemployment rate of 21.8% showed improvement over January’s 22.5% rate and was a substantial drop from February 2010’s 27.1%, but the industry’s jobless level remains the highest among U.S. industries, according to the latest Bureau of Labor Statistics report.

Released on March 4, the BLS report shows that construction gained 33,000 jobs in February. However, BLS notes that the industry’s February pickup in jobs followed a January loss of 22,000 jobs, which “may have reflected severe winter weather.”
