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.
