Case-Shiller Home Price Index
The S&P/Case-Shiller Home Price Indices measure the nominal value of the residential real estate market in 20 metropolitan regions in the United States. The indices use repeat sales pricing technique to evaluate the housing markets. The approach, developed by economists Karl Case, Robert Shiller and Allan Weiss, uses data on single-family home re-sales, and re-sold sale prices to form sale pairs. This index family includes 20 regional indices and two composite indices as aggregates of the regions.
