From today's New York Times...

Last year, 37 percent of 18-to-29-year-olds were unemployed or no longer looking for work.

The portion of 18-to-29-year-olds who live alone declined to 7.3 percent in 2009 from 7.9 percent in 2007, according to the Current Population Survey. A decline that large was recorded only twice before, during or after recessions in the early 1980s and 1990s.

According to the census, 56 percent of men age 18 to 24 and 48 percent of women in the same age group live under the same roof as their parents.
