The wealth gaps between whites and minorities in the United States have grown to their widest levels since the US government began tabulating them a quarter-century ago. The recession and uneven recovery have erased decades of minority gains, leaving whites on average with 20 times the net worth of blacks and 18 times that of Hispanics, according to an analysis of new Census data. The analysis shows the racial and ethnic impact of the recent economic meltdown, which ravaged housing values and sent unemployment soaring. It also offers the most direct governm ent evidence yet of the stark wealth divide, a disparity between predominantly younger minorities whose main asset is their home and older whites who are more likely to have 401(k) retirement accounts or other stock holdings. “I am afraid that this pushes us back to what the Kerner Commission characterized as ‘two societies, separate and unequal,'” said Roderick Harrison, a former chief of racial statistics at the Census Bureau, referring to the 1960s presidential commission that examined US race relations. “The great difference is that the second society has now become both black and Hispanic.” The median wealth of white US households in 2009 was $113,149, compared to $6,325 for Hispanics and $5,677 for blacks, according to the analysis released Tuesday by the Pew Research Center. Those ratios, roughly 20 to 1 for blacks and 18 to 1 for Hispanics, far exceed the low mark of 7 to 1 for both groups reached in 1995, when the nation's economic expansion lifted many low-income groups to the middle class. The white-black wealth gap also is the widest since census began tracking such data in 1984, when the ratio was roughly 12 to 1. “What's pushing the wealth of whites is the rebound in the stock market and corporate savings, while younger Hispanics and African-Americans who bought homes in the last decade, because that was the American dream, are seeing big declines,” said Timothy Smeeding, a University of Wisconsin-Madison professor who specializes in income inequality.
