Kenedy County, Texas has the highest rate of uninsured residents in the country at 46.3 percent, according to new data released Aug. 3 by the U.S. Census Bureau.
The new data is from 2021 and comes from the Small Area Health Insurance Estimates program, which is the only comprehensive source for single-year estimates of health insurance coverage in each of the country's 3,142 counties.
Between 2020 and 2021, the rate of Americans under 65 without health insurance decreased in 280 counties and increased in 80 counties. County uninsured rates ranged from 2.4 percent to 46.3 percent, with a median county uninsured rate of 10.4 percent.
The Northeast and Midwest had the nation's largest share of counties with uninsured rates below 10 percent, and the South had the largest share of counties with uninsured rates above 15 percent.
The nation's uninsured rate hit a record low of 7.7 percent in the first quarter of 2023, according to data published Aug. 3 by the CDC. The record rate does not reflect the millions of people removed from Medicaid during the redeterminations process, which began in April.
