Nearly 17 percent of Tennesseans living in shared households in 2011 were also living in poverty, according to U.S. Census Bureau statistics released Wednesday.

In broader terms in 2011, 41.9 million people 18 and older lived in someone else's household, up from 16 percent in 2007, prior to the start of the economic recession, the census numbers show. Between 2010 and 2011, the number of these additional adults increased by 1.9 million, from 17.3 percent to 17.9 percent of adults.
