Sixty-two percent of Hispanic adults ages 19 to 64 were uninsured at some point during the year, compared with 20 percent of white working-age adults and 33 percent of African-American adults, according to a survey by the Commonwealth Fund.

Seventy-six percent of Hispanic adults with low incomes were uninsured at some point during the year, compared to 44 percent of African Americans and 46 percent of whites with low incomes.

"These findings are extremely troubling, and indicate missed opportunities to ensure a healthy and productive workforce," says Karen Davis, president of the Commonwealth Fund. "Minority Americans face persistent disparities in rates of health care coverage, as well as cost and access barriers to care even when they do have health insurance."

The Commonwealth Fund's survey was conducted by Princeton Survey Research Associates International from August 18, 2005 through January 5, 2006. The survey included more than 3,000 working-age adults.
