About one in three Americans age 65 or older lived in low-income families in 2009, including 8.9 percent in poverty. Poverty rates were much higher among those who did not complete high school, lived alone, or had poor health. This data brief reports how poverty and near-poverty rates among older Americans in 2009 varied by demographics, living arrangements, and health status; shows that poverty and near poverty among seniors declined between 2007 and 2009; and describes income sources for poor and non-poor seniors.
