Frequently asked questions

What percentage of US adults below the poverty line are uninsured?
In 2023, 21.1% of working-age adults (19–64) below 138% of the federal poverty level were uninsured, per 2023 ACS B27016 estimates. This is the Medicaid eligibility threshold in expansion states; higher rates persist in non-expansion states.
Are employed workers in the US insured?
Not all. 10.0% of employed workers aged 19–64 were uninsured in 2023 (2023 ACS B27011). This gap is largest in states with many low-wage, part-time, or gig-economy jobs that don't offer employer insurance.
Why do children have a lower uninsured rate than adults?
Children aged under 19 had a 6.0% uninsured rate in 2023 β€” lower than the 11.3% for working-age adults β€” primarily because Medicaid and CHIP cover most low-income children in all 50 states. Adults in non-expansion states can fall into a coverage gap.
What is the Gera Coverage Gap Score (GCGS)?
GCGS = round(state_rate Γ· national_rate Γ— 100) for a specific demographic band. A GCGS of 100 means the state's uninsured rate for that demographic equals the US average. Above 100 = wider gap; below 100 = narrower gap. See the full methodology at https://geraclinic.com/us/insurance-demographics/methodology.
Which state has the highest working-age uninsured rate?
Texas had the highest working-age (19–64) uninsured rate in 2023 at 21.6%, giving a GCGS of 191 (far above national average vs the US average of 11.3%). Source: 2023 ACS B27001.
