Joblessness in June was lower than a year ago in all of Washington state’s 39 counties, according to Employment Security Department data released Tuesday.

King County’s unemployment rate stayed the same from May to June at 4.7 percent, up slightly compared to April’s low of 4.3 percent, but down from 5.5 percent in June 2013.

In Snohomish County, joblessness stayed the same over the month as well at 5.1 percent, down from 6.2 percent last year.

Pierce County’s rate dropped to 6 percent in June, down from 7.1 percent in May and 8.2 percent a year ago.

The county unemployment data are not seasonally adjusted for month-to-month fluctuations and are based on a household survey.

As previously reported, the statewide seasonally adjusted unemployment rate declined to 5.8 percent in June, a level not seen since September 2008.
