Almost one-third of people under 65 in the Florida county of Miami-Dade and one-fourth in Broward County, FL, lacked health insurance in 2005, according to Census Bureau figures. As have many other studies, the report found a wide disparity among racial-ethnic groups. Hispanics in Florida were far more likely to be uninsured, at 38.6%. Black non-Hispanics had a 26.7% rate, the highest rate for blacks found anywhere in the country.
