The Federal Reserve Board's Survey of Consumer Finances for 2010 provides insights into changes in family income and net worth since the 2007 survey. The survey shows that, over the 2007–10 period, the median value of real (inflation-adjusted) family income before taxes fell 7.7 percent, while mean income fell more sharply, an 11.1 percent decline. Both median and mean net worth decreased even more dramatically than income over this period, though the relative movements in the median and the mean are reversed; the median fell 38.8 percent, and the mean fell 14.7 percent.

The report indirectly makes an observation about generational divides:
The decline in median income was widespread across demographic groups, with only a few groups experiencing stable or rising incomes.Most noticeably, median incomes moved higher for retirees and other nonworking families.
