(WXIA) -- In 2012, 36% of adults ages 18 to 31 were still living in their parents' homes -- the highest number in more than 40 years.
The Pew Research Center analyzed U.S. Census Bureau data in the study released this month.

A record total of 21.6 million Millennials (the name given to the generation spanning 18-31) lived in their parents' homes in 2012. That's up from 18.5 million in 2007 when the great recession began.
Men are more likely than women to be living with parents (40% vs. 32%). That's part of a long-term gender gap. Researchers say it's because females finish college faster than males and form intimate relationships earlier. The median age for marriage in 2012 was 26.6 for women and 28.6 for men.
Ironically, this same age group experienced declining unemployment. In 2012, 63% of 18-31 year olds had jobs, down from 70% in 2007.
College could help explain some of those numbers. More young adults are going to school. Students living in dorms are also counted as "living at home."
