A new Congressional Research Service report by Linda Levine is the first update on the distribution of wealth (including that of the top 1 percent) I’ve seen based on the recently released Federal Reserve Board (FRB) data on wealth for 2010. Levine’s analysis (see two of her tables below) shows a large upward change in the distribution of wealth over 2007-2010, with losses in the bottom 90 percent and large gains for the top 10 percent. Specifically, the bottom 90 percent in 2010 had just 25.4 percent of all wealth, down from 28.5 percent in 2007. The gainers were primarily those in the 90-to-99th percentiles (up 2.3 percentage points) of wealth, though the top 1 percent saw gains (up 0.7 percentage points) too. Levine’s data goes back to 1989 and show the wealth share of the bottom 90 percent to be at its lowest in 2010, far lower than the 32.9 percent share in both 1989 and 1992.
