Hawaii’s seasonally adjusted unemployment rate plunged three-tenths of a point in July to 3.7 percent, its lowest level in more than seven years, as the state economy continued strengthening.

The last time the jobless rate was lower was in April 2008 when it was 3.6 percent. This is also the first time since May 2008, when it was 3.8 percent, that the rate has been lower than 4 percent.

The number of payroll jobs, however, declined by 2,000 jobs to 632,700, according to the state Department of Labor and Industrial Relations.
