On a seasonally adjusted basis, the statewide jobless rate dropped to 5 percent in April, from 5.2 percent March. Initial statewide figures were released last week.

Only two Colebrook sections of Coos County showed an increase in unemployment. One of those areas includes a portion that is in Vermont.
