The S&P/Case Shiller Home Price Indices, which track home prices
throughout the U.S. on a two-month lag, declined 3.9 percent during the fourth quarter of 2010 on
top of a 1.9 percent decline in Q3. Prices were 4.1 percent lower than one
year earlier. This represents the lowest
annual growth rate since the third quarter of 2009 when prices were falling at
an 8.6 percent annual rate and the sixth consecutive month of national home price depreciations.
S&P/Case-Shiller provides two monthly indices which
track the price path of single family homes in a 10-City and a 20-City data
base. Each index combines matched price
pairs from sales of individual homes.
The National Housing Index tracks home value data for the nine U.S.
Census divisions and is calculated quarterly.
All indices are based on a value of 100 which represents home prices in
January 2000. A current index value of
150 percent would translate to a 50 percent appreciation in price since that
date.
The Chart below shows the levels of the U.S. National Home Price Index as well as its annual
returns. After recovering slightly over
several quarters from the trough that home prices reached in Q1 2009, the
National Index has dropped nearly back to that level and now approximates home
prices in early 2003.

S&P/Case-Shiller provides its data in both seasonally
adjusted (SA) and non-seasonally adjusted form but recommends relying on the
latter.
19 of 20 Metropolitan Statistical
Areas (MSA) in the 20-City Index reported declines during in the November/December
period with Tampa down 2.6 percent; Detroit off 2.3 percent; and Seattle
declining 2.0 percent. Only Washington
DC showed an increase, a slight 0.3 percent.
In December, 11 MSAs fell to new index lows following their peaks in
2006/2007. For nine of these MSAs,
Atlanta, Charlotte, Chicago, Detroit, Las Vegas, Miami, Seattle, Tampa, and
Portland (OR) it was the second record setting month in a row; New York and
Phoenix were newcomers to the list.
David M. Blitzer, Chairman of the Index Committee at
Standard and Poor's said, "We ended 2010 with a weak report. Unlike the 2006 to 2009 period when all cities
saw prices move together, we see some differing stories around the
country. California is doing better with
gains from their low points in Los Angeles, San Diego and San Francisco. At the other end is the Sun Belt - Las Vegas,
Miami, Phoenix and Tampa. All four made
new lows in December. Also seeing
renewed weakness are some cities that were among the last to reach their peaks
including Atlanta, Charlotte, Portland OR and Seattle."
Blitzer said that Cleveland and Las Vegas have joined
Detroit with average home prices below the January 2000 base period.
