The S&P/Case-Shiller index covers roughly half of U.S. homes. It measures prices compared with those in January 2000 and creates a three-month moving average. The October figures are the latest available.
Steady gains in home prices have helped drive a modest recovery in the housing market. Rising prices encourage more potential buyers to come off the sidelines and purchase homes. And more people may put their homes on the market as they gain confidence that they can sell at a good price.
Higher home prices can also make homeowners feel wealthier and more likely to spend more. Consumer spending accounts for about 70 percent of the U.S. economy.
