A family of
S&P indices created by Karl Case, Robert Shiller, and Allan Weiss used to measure the
nominal value of home prices in the U.S. The Case-Shiller Indices, which are based on 20 metropolitan statistical areas (MSAs), use data on single-family homes sold more than once (resale homes) and re-sold sale prices to provide a weighted and quality-adjusted assessment of the
real estate market. Calculated each month by Fiserv, Inc., the family of
indices consists of 20 MSA
indices and two aggregated
indices.
