What is a Case-Shiller Index? – David Reecher
The Case-Shiller index refers to several indices that measure home prices across the United States on a point system (with January 2000 set at 100). The Case-Shiller U.S. National Home Price Index tracks prices of single-family homes in each of the nine U.S. Census divisions. The rest of the Case-Shiller indices rely on data from major metropolitan areas in the U.S. to measure the average change in home prices. The Case Shiller 10-city composite index aggregates data from Boston, Chicago, Denver, Las Vegas, Los Angeles, Miami, New York, San Diego, San Francisco, and Washington DC. The Case-Shiller 20-city composite index adds data from the following ten cities: Atlanta, Charlotte, Cleveland, Dallas, Detroit, Minneapolis, Phoenix, Portland, Seattle, and Tampa. Each of these major metropolitan areas has their own Case-Shiller index. All Case-Schiller indices exclude condominiums, apartments, multi-family dwellings, and other properties that are not single-family homes. The indices also exclude new construction and homes that have been significantly altered to improve value (e.g. a one-bedroom home is remodeled to a three-bedroom home).
