About this ranking

Published percentage change from the previous year in the FHFA all-transactions house price index for US counties.

Developmental nominal series, not seasonally adjusted. Includes sale prices and refinance appraisals, unlike purchase-only series. Uses the published annual change directly; it is unaffected by the index base year. Missing estimates remain absent and historical estimates can be revised.

Every value in the ranking comes from the same publisher and the same period, so the counties are compared on one definition. Equal values share a rank.
