Clark County’s population is still growing at a fast clip, but the growth rate may have reached its peak.
The county gained an estimated 8,500 people and grew 1.8 percent between April 2017 and April 2018, making it only the eighth fastest-growing county in Washington, according to data released Tuesday by the state Office of Financial Management. An estimated 479,500 people live in Clark County.
Franklin and Benton counties, which make up the Tri-Cities, along with Snohomish and Skagit counties north of Seattle, were the fastest-growing. Historically, Clark County has been among the state’s fastest-growing places. The other faster-growing counties this year were Kittitas (Ellensburg), Whatcom (Bellingham), and San Juan.
“It is still relatively strong growth,” said Mike Mohrman, senior forecast analyst with the Office of Financial Management. “These things go in cycles along with the economy.”
He said there’s no strong indicators that there will be any great change to this pattern and expects the state population to keep rising. Washington’s businesses, mild climate and natural surroundings continue attracting people to this part of the country. The state’s population grew by an estimated 1.6 percent to 7,427,570 residents.
