Washington’s county jobless rates for August were released today, showing a South Sound unemployment picture that has remained relatively flat month to month.

Pierce County’s unemployment rate, non-seasonally adjusted, stayed at 5.0 percent in August after recording the same figure in July. The jobless rate sustained a year-over-year improvement that’s trended similarly over the summer, with August 2016 showing unemployment at 6.3 percent.

The story is much of the same in Thurston County, where the unemployment rate fell slightly to 4.6 percent in August from 4.7 percent in July. That’s down year over year from August 2016’s 5.7 percent jobless rate.

The two main South Sound counties remain among the top half of counties in the state when it comes to low unemployment. Asotin County leads Washington with 3.4 percent unemployment; King County is among the leaders at 3.8 percent.

Mason and Lewis Counties, on the other hand, remain near the bottom of the unemployment rankings, though neither is close to Ferry County’s 9.6 percent unemployment rate, worst in the state. Lewis is at 6.1 percent in August, up from 6.0 percent in July but way down from 7.9 percent in August last year. Mason County is at 5.7 percent, down from 5.8 percent in July and down sharply from 8.0 percent in August 2016.
