The American Community Survey (ACS) published data in December showing people living in poverty tend to be clustered in certain neighborhoods rather than evenly distributed across geographic areas. The ACS, which includes socioeconomic data on every community in the nation for the combined years from 2006 to 2010, found that 23 percent of the nation’s population live in census tracts with poverty rates of 20 percent or higher.

Among states, the percentage ranged from 46 percent in Mississippi to 5 percent in New Hampshire. The ACS also covers many topics including educational attainment, income, occupation, commuting to work, nativity, ancestry and monthly housing costs.
