The authors of this brief examine child poverty rates using decennial census data from 1980, 1990, and 2000, as well as American Community Survey five-year estimates between 2005 and 2009, to identify those counties where child poverty has persisted. They find persistent child poverty in nearly twice as many U.S. counties as those that report high persistent poverty across all age groups. In all, 342 counties have experienced persistently high levels of poverty across all age groups during the past twenty-nine years. In contrast, more than 700 counties experienced persistent child poverty over the same period. Rural areas are disproportionately likely to have persistent high child poverty; 81 percent of counties with persistent child poverty are nonmetropolitan while only 65 percent of all U.S. counties are nonmetropolitan. Overall, 26 percent of rural children reside in counties whose poverty rates have been persistently high. This compares with 12 percent of urban children. Counties with persistent child poverty cluster in Appalachia, the Mississippi Delta, other areas of the Southeast, parts of the Southwest, and in the Great Plains. The authors comment that the overwhelming urban focus of welfare programs means policymakers often overlook needy families in rural areas. In addition to the high unemployment and low education levels that they document in the brief, the physical and social isolation associated with rural poverty create problems different from those in densely settled urban areas. They conclude that the reductions in government spending likely to result from the Great Recession, coupled with two decades of the devolution of policymaking responsibility from the federal to the state level (and occasionally to municipal governments), may have significant implications for children and fragile families in these persistently poor rural counties.
