Wealth Distribution - Mean and Median by Age

From 2007 Survey of Consumer Finances
4. Family net worth, by selected characteristics of families, 1989–2007 surveys

Mean Net Wealth is higher than median, so the distribution is skewed toward the higher net wealth.

The ratio of mean to median has increased for every group except 75 or more, so the distribution has become more skewed.

Median wealth begins decreasing for people entering the 65+ age group. Mean welath increases even after age 65 in 2007. This changed between 2004 and 2007. The 2004 data (which is also in Table 4), shows mean wealth decreasing after 65.
