Home Price Index
Definition
A Home Price Index (HPI) is a statistical measure that examines the relative level of prices of housing within a specific market during a particular time period. The index values are typically pegged to a base or starting value, allowing users to track changes in home prices over time rather than providing actual dollar amounts of average or median home prices.
Examples
- Case-Shiller/S&P Home Price Index: One of the most well-known HPIs, developed by economists Karl Case and Robert Shiller. It measures the repeat sales price changes across 20 major metropolitan areas in the United States.
- FHFA House Price Index (HPI): This index, provided by the Federal Housing Finance Agency, includes all transactions involving conforming, conventional mortgages purchased or securitized by Fannie Mae or Freddie Mac.
Frequently Asked Questions (FAQs)

A: The base value is an arbitrary starting point for the index, usually set at 100 during a specific year. Changes in the index are calculated relative to this base value.
Q: How often are Home Price Indexes updated?
A: HPIs like the Case-Shiller/S&P and FHFA indices are typically updated monthly or quarterly, providing recent data on housing market trends.
Q: Why is a Home Price Index useful?

A: Yes, HPIs can cover various regions, from national levels to specific metropolitan areas. For example, the Case-Shiller/S&P index covers 20 major U.S. metropolitan areas.
Q: How is an HPI calculated?
