Washington’s unemployment rate fell from 4.6 to 4.5 percent in October, equaling the state’s all-time low for unemployment set earlier this year.

“Washington’s economy keeps growing,” said Paul Turek, economist for the state’s Employment Security Department. “The demand for workers remains strong with ample opportunity for employment.”

In October last year, the statewide unemployment rate was 5.3 percent. Washington added 6,900 nonfarm jobs in October and added an estimated 105,800 new jobs from October 2016 to October 2017 (not seasonally adjusted). Year over year, the private sector grew by 3.4 percent or 91,000 jobs, and the public sector increased by 2.5 percent, adding 14,800 jobs.

Construction saw the largest employment gains year-over-year, with 17,100 new jobs. Twelve of the state’s 13 industry sectors added jobs, with manufacturing — losing 1,600 — the only sector to report job losses.

The labor force — the number of people over the age of 165 both employed and unemployed — rose to 3.76 million, growing by 14,100 from the previous month. The labor force grew by 98,700 from October 2016 to October 2017.
