The wealth gaps between whites and minorities have grown to their widest levels in a quarter-century. 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.

Some highlights:

—About 35 percent of black households and 31 percent of Hispanic households had zero or negative net worth in 2009, compared with 15 percent of white households. In 2005, the comparable shares were 29 percent for blacks, 23 percent for Hispanics and 11 percent for whites.

—Asians lost their top ranking to whites in median household wealth, dropping from $168,103 in 2005 to $78,066 in 2009. Like Hispanics, many Asians were concentrated in states like California hit hard by the housing downturn. More recent arrivals of new Asian immigrants, who tend to be poor, also pushed down their median wealth.

—Across all race and ethnic groups, the wealth gap between rich and poor widened. The share of wealth held by the top 10 percent of U.S. households increased from 49 percent in 2005 to 56 percent in 2009. The threshold for entry into the wealthiest top 10 percent, however, dipped lower: from $646,327 in 2005 to $598,435.
