Behind the Numbers

Market Values

Median prices and foreclosure counts of homes and condominiums in King County were supplied by the King County Assessor’s office and calculated by the King County GIS Center. Median prices of homes and condominiums in Kitsap, Pierce, and Snohomish counties were provided by the Northwest Multiple Listings Service. Foreclosure totals outside of King County were analyzed and supplied by Washington Property Solutions.


The geographical research and mapping software firm ESRI calculated the demographic data using the 2010 U.S. census, including estimates of population by age and race; percentage of owner-occupied, renter-occupied, and vacant homes; and median household incomes.


ESRI also calculated indexes to show how Seattleites compare to national averages. A value of 100 represents the national average. Any value above 100 means that Seattleites rank higher than the national average, and values below 100 means Seattleites rank lower than average. The Health Index is based on household gym and yoga memberships and average household spending for outdoor gear. More detailed information on ESRI’s sources and methodologies can be found at
