Qian's brief is based on census data and shows that the trend of young adults staying with their parents occurred across the U.S. but was strongest in large metropolitan areas with both high living costs and high unemployment.  The top 10 metropolitan areas on his ranking included New York, Miami, Honolulu and El Paso, Texas.  Columbus Ohio had one of the lowest percents of young adults aged 25-29 living with parents between 2007-2009 (11%).  This research has been featured in a number of news outlets including USA Today, Los Angeles Times, US News and World Report, Atlantic and Huffington Post.”  The entire brief can be found at http://www.s4.brown.edu/us2010/Data/Report/report08012012.pdf
