Homeowner Age and House Price Appreciation
AHEAD = Assets and Health Dynamics Among the Oldest Old Study. CAGR = compound annual growth rate.
CODA = Children of the Depression Age. HRS = Health and Retirement Study. WBs = War Babies.
* Values in this column are in percent unless designated by a dollar sign.
** Indicates that the differences between the HRS/WB and AHEAD/CODA groups are statistically signicant at the 1-percent
level. χ

tests were conducted for cross-tabulation comparisons and t-tests were performed for average comparisons. The
observation level of the sample in this article is a primary home. Some households have as many as three primary homes in
the survey period from 1992 through 2002. Only single-family, nonfarm, nonmobile, and noncondominium owned primary
homes are considered in the sample, which is also conned to homes with nonimputed and nonmissing house values
reported by respondents in both start and end years. The sample sizes and medians presented in this exhibit are unweighted,
but the percentages and averages reported are weighted using household weights provided by HRS/AHEAD to make
inference on the U.S. population of the same age, gender, and race/ethnicity prole as that of the HRS/AHEAD sample. All
dollar amounts are adjusted to 2002 using the nonseasonally adjusted Consumer Price Index excluding shelter expenses.

From the tracker and region les, characteristics of the nancial respondent for each wave were obtained. Where there were
no nancial respondents, characteristics of the family respondent were obtained. Where the information on respondent type
was unavailable, characteristics of the oldest respondent were obtained. Information on homes, such as house values, was
obtained from the year-specic HRS/AHEAD survey data les.
b
CAGR = (FV/PV)1/n – 1, where PV is the beginning value, FV is the ending value, and n is the number of intervening years.
This measure is very similar to ln(FV/PV)/n, which assumes continous compounding. We prefer CAGR because most house
price growth rates, like interest rate growth rates, are reported in annual growth rates.
c
Medians are calculated without weights and no statistical tests for signicance of the difference between the younger and
older groups were conducted.
