More young adults than ever are living with their parents—and this trend could just be getting started.

The share of adults aged 20-34 living at home rose to 24 percent during the recession, up from 17 percent in 1980, according to a study by Ohio State's Zhenchao Qian.

Too many young people are unemployed or terrified of losing their jobs, not to mention scared of the long-dismal housing market.

Qian also noted secular trends that are keeping kids at home like the declining marriage rate. He also found that men and non-white groups are more likely to live at home.

We've picked out the ten cities with the most young adults living at home. This list includes several notable centers of inequality like Bridgeport, NYC and LA. These may be places where home prices remain too high for millennials.

As several commenters pointed out below, this may not be a bad trend.
