OLYMPIA — After eight months at 5.8 percent, preliminary estimates from the federal Bureau of Labor Statistics show Washington’s seasonally adjusted unemployment rate shook free and fell to 5.7 percent in August despite more people joining the labor force.

According to the Monthly Employment Report from Washington’s Employment Security Department (ESD), the state added 2,600 jobs in August. July’s preliminary gain of 2,600 jobs was revised down to 1,900.

“While the unemployment rate didn’t change dramatically, it’s a positive move none the less, considering the state’s labor force continues to grow,” said Paul Turek, the state’s labor market economist.

The national unemployment rate held firm at 4.9 percent in August. The unemployment rate in the Seattle/Bellevue/Everett area dropped from 4.4 to 4.1 percent in August.

ESD paid unemployment insurance benefits to 52,719 people in August.

Labor force increases in Washington

The state’s labor force grew to 3.63 million in August, an increase of 7,400 people from the previous month. In the Seattle/Bellevue/Everett region, the labor force increased by 8,000 during the same period.

From August 2015 to August 2016, the state’s labor force grew by 89,000 and the Seattle/Bellevue/Everett region increased by 29,300.

The labor force is the total number of people, both employed and unemployed, over age 16.
