A recently released report by family health-care advocacy group Families USA, “Too Great a Burden: America’s Families at Risk,” found that a disproportionate number of the nation’s minorities were uninsured in 2006 and 2007.

The report found that 60.7 percent of Latinos, 44.5 percent of African-Americans, 38.2 percent of people composed of other ethnicities and 26 percent of whites were uninsured in those years.

Rising health care costs and the health insurance woes of Americans have received increased attention as presidential candidates have discussed their proposals to insure more people. A growing number of families will continue to spend more of their family budgets on health care costs next year, according to the report.

In Iowa, 701,000 people under the age of 65 are members of families who will spend more than 10 percent of their pre-tax family income on health care in 2008, according to the report.
