The number of unemployed people declined 8,800 over the year to 30,200.

The nationwide unemployment rate of 5.1 percent was the same as the previous month and down from 5.9 percent a year ago. New England’s unemployment rate was 4.6 percent.

State officials say the estimate of the employment to population ratio of 59.9 percent was also the lowest in more than three years. The U.S. average was 59.2 percent.
