Puget Sound Population Surge Led by Seattle, King County

As of April 1, 2025, the Puget Sound region reached a population of 4,534,300, growing by 50,400 people over the past year. This growth was led overwhelmingly by King County, which added 33,600 residents—accounting for two-thirds of the region's total increase. Seattle alone contributed nearly 19,000 new residents, surpassing 816,000 and outpacing the combined growth of Snohomish and Pierce counties. While Snohomish (+6,700) and Pierce (+7,300) counties saw steady, modest increases, growth in transit-connected suburbs like Shoreline and Redmond stood out. Kitsap County grew by 2,800, maintaining its trend of stable, moderate expansion. Overall, the region’s growth reflects continued urban and transit-oriented population shifts, even as statewide growth slows compared to previous years.

Governor Signs Into Law Buildable Lands Bill

New Law Will Improve the Methodology and Process Used to Assess Buildable Lands

Bellevue, Wash—July 7, 2017—Governor Jay Inslee yesterday signed into law Senate Bill 5254, ensuring adequacy of buildable lands and zoning in urban growth areas. The bill, sponsored by Senator Joe Fain (R-47th District), will improve the methodology and process by which local jurisdictions assess buildable lands.

Nick Harper, senior director of strategy & policy at the Master Builders Association of King and Snohomish Counties, explained the significance of the bill, which has been a top legislative priority for the association. “The bill’s passage represents a major step forward for the buildable lands process by ensuring greater accuracy of information used to plan for growth,” he said. 

“The new law brings more specificity into what items must be reviewed to determine whether lands are buildable or what density could be achieved,” Harper added. “More accurate buildable lands data should help our region do a better job of utilizing existing land supply and infrastructure to meet current and future housing demand.”

The new law also provides increased certainty and flexibility for local jurisdictions to assist in funding low-income and homelessness programs.

The Growth Management Act requires King, Snohomish, Pierce, Clark, Thurston, and Kitsap counties to establish a buildable lands program to determine whether the counties and cities within them are achieving urban growth within their urban growth areas. Senate Bill 5254 adds Whatcom County to the list of counties participating in the buildable lands program. View the House Bill Report for Senate Bill 5254.
