Review of Health Insurance Coverage Data in 2021: Releases and Resources

Each year, SHADAC covers the releases of health insurance coverage data from major federal surveys such as the American Community Survey (ACS) and Current Population Survey (CPS), both of which are overseen by the U.S. Census Bureau.¹ Not only do these data provide an understanding of trends for the millions of individuals in the United States who lack any type of coverage, but they also give indications of changes in other major forms of health insurance, like public coverage, private coverage, and employer-sponsored coverage.

SHADAC researchers work to provide insights into these data in a variety of formats (including reports, blog posts, and webinars) and analyze a multitude of important demographic groups (children, families living below poverty levels, and for communities of color). We also know that to truly understand the trends and vagaries of health insurance coverage, it’s important to look beyond national-level statistics, to see what’s happening at the state level.

That’s why we recently updated one of the longest-running measures on SHADAC’s data tool, State Health Compare, “Health Insurance Coverage Type” with the latest data for 2021. Users can take a look at estimates of health insurance coverage across all 50 states by type (uninsured, employer-sponsored, Medicaid/CHIP, etc.), by categories (age, education level, race/ethnicity, marital status, poverty level, etc.),² over time (from 2008-2021),³ and can even examine estimates using color-coded maps, trend and bar charts, or by ranking states in terms highest and lowest rates for any coverage type.

2021 Key Findings

After multiple disruptions to data collection efforts resulted in data quality issues for 2020 ACS estimates, SHADAC is excited that data for 2021 are able to be used with confidence once again—though users are cautioned not to compare data to the prior year. Nationally, the U.S. saw a near-record low rate of uninsurance in 2021, at 8.6%, second only to a rate of 8.5% in 2016.

Looking at the state level, however, shows much wider variation in uninsured rates, from a low of 2.4% in Massachusetts to a high of 17.9% in Texas. By larger demographic groups:

• Among children (age 0-18), 5.4% were uninsured in 2021; however, by state, this ranged from 1.1% in Massachusetts to 11.8% in Texas.
• Among those below the poverty level, 15.6% were uninsured in 2021; however, by state, this ranged from 4.4% in Vermont to 30.5% in Texas.
• Among individuals with less than a high school degree, 22.2% were uninsured in 2021; however, by state, this ranged from 5.9% in Massachusetts to 41.4% in Texas.
• Among people reporting “Fair” or “Poor” health status, 25.9% were uninsured in 2021; however, by state, this ranged from 17.9% in Louisiana to 44.7% in Utah.
