Pursuant to a congressional request, GAO: (1) identified census tracts in medium-sized to large cities that met specific poverty criteria; and (2) provided additional information on each census tract.

GAO noted that: (1) for each selected metropolitan statistical area, GAO identified the number of census tracts in which 50 percent or more of the households are at or below the poverty level, the number of tracts in which 75 or more of the households are at or below the poverty level, and the total number of census tracts; and (2) for each of these census tracts, GAO provided information on the median household income and the number of households in four income ranges.
