NEW YORK, NOVEMBER 24, 2020 – S&P Dow Jones Indices today released the latest results for the S&P CoreLogic Case-Shiller Indices, the leading measure of U.S. home prices. Data released today for September 2020 show that home prices continue to increase across the U.S. More than 27 years of history are available for these data series, and can be accessed in full by going to https://www.spglobal.com/spdji/.

The S&P CoreLogic Case-Shiller U.S. National Home Price NSA Index, covering all nine U.S. census divisions, reported a 7.0% annual gain in September, up from 5.8% in the previous month.

The chart below is an overlay of the Case-Shiller 10- and 20-City Composite Indexes along with the national index since 1987, the first year that the 10-City Composite was tracked. Note that the 20-City, which is probably the most closely watched of the three, dates from 2000. We’ve used the seasonally adjusted data for this illustration.

Home Price Index

For a long-term perspective on home prices, here is a look at the seasonally and inflation-adjusted Case-Shiller price index from 1953, the first year that monthly data is available. Because the CPI owners’ equivalent rent of residences didn’t start until 1983, we’ve used the broader seasonally adjusted Consumer Price Index, which is why this looks different from the real inflation-adjusted indexes two charts above.

To get an even better idea of the trend in housing prices over long time periods, we compare the change in the seasonally-adjusted Case-Shiller Home Price Index and the Consumer Price Index since 1953.
