Last year, the population of King County grew 48,600, or 2.3%. The housing stock grew 14,700, or 1.6%. The gap, 0.7%, is a rough measure of our failure to create enough housing.
This is the sixth straight year when population growth exceeded housing creation in King County. Snohomish and Pierce appeared more balanced until 2014, but now face heightened housing pressures as displacement of King County workers from expensive local housing markets grows.
