The data is not encouraging — King County scores just 1/100 on the Boom Town Index, ranking #986 of 1001 counties. Job growth at -0.9% and median household income of $124,746 reflect an economy that has been contracting or stagnating relative to the rest of the country.
Affordability is a real challenge in King County. The median home is valued at $859,900 — with an income-to-home-value ratio of just 0.15, that's significantly harder to afford than in most U.S. counties. Median rent runs $2,092/month.
King County's population is growing — up +1.1% YoY — while the job market is roughly flat (employment change of -0.9%). Home values shifted -2.7% over the past year. In-migration is outpacing local hiring, which often points to remote workers or retirees driving the headcount.
