The number and share of Americans living in multi-generational households rose for all age groups from 2007 to 2009, but the sharpest growth was for adults ages 25 to 34. Their numbers increased from 7.4 million to 8.7 million during that period.
Large numbers of Americans enacted their own anti-poverty program in the depths of the Great Recession: 51.4 million Americans lived with relatives in 2009, an increase over the 46.5 million who did so in 2007.
