"There is the real possibility that white alienation will increase if steps are not taken to highlight and address inequality on a broad front," Wilson said.
Nationwide, the count of America's poor remains stuck at a record number: 46.2 million, or 15 percent of the population, due in part to lingering high unemployment following the recession. While poverty rates for blacks and Hispanics are nearly three times higher, by absolute numbers the predominant face of the poor is white.
More than 19 million whites fall below the poverty line of $23,021 for a family of four, accounting for more than 41 percent of the nation's destitute, nearly double the number of poor blacks.
Sometimes termed "the invisible poor" by demographers, lower-income whites generally are dispersed in suburbs as well as small rural towns, where more than 60 percent of the poor are white. Concentrated in Appalachia in the East, they are numerous in the industrial Midwest and spread across America's heartland, from Missouri, Arkansas and Oklahoma up through the Great Plains.
Buchanan County, in southwest Virginia, is among the nation's most destitute based on median income, with poverty hovering at 24 percent. The county is mostly white, as are 99 percent of its poor.
More than 90 percent of Buchanan County's inhabitants are working-class whites who lack a college degree. Higher education long has been seen there as nonessential to land a job because well-paying mining and related jobs were once in plentiful supply. These days many residents get by on odd jobs and government checks.
