FHFA notes: The FHFA HPI is a broad measure of the movement of single-family house prices. The FHFA HPI is a weighted, repeat-sales index, meaning that it measures average price changes in repeat sales or refinancings on the same properties. The line above is FHFA's standard quarterly all-transactions index for the metropolitan area; the comparison table below uses FHFA's annual CBSA index, which FHFA describes as developmental. The index does not give a dollar value for any home.

FHFA reports each index with a value of 100 in its base period, the first year the area has enough transactions (1977 here). A decade's change is the index at the end of the decade divided by the index at the start, so it does not depend on the base year; the United States column covers the same years. Decades before 1977 are not shown.
