U.S. states ranked by uninsured rate
Compare all 50 states by the share of residents without health insurance in the 2020–2024 ACS. See uninsured counts, the all-age universe and source limits.
Which states have the highest uninsured rates?
Texas has the highest point estimate, 17.1%, for 2020–2024. Next are Oklahoma (12.9%) and Georgia (12.4%) .
Texas has the highest point estimate for the uninsured share in this collection. The percentage and the number of uninsured residents answer different questions, so both are provided in the downloadable data.
The population universe is civilian noninstitutionalized residents of all ages. It excludes active-duty Armed Forces members and residents of institutions. This is not an under-65-only coverage measure.

National benchmark and District of Columbia
The United States value is 8.4%. The District of Columbia value is 3.6%. Both use the same source product as the state table. They do not receive a numbered state position. The national estimate is a source value or an approved calculation from national source counts; it is not an average of the state medians or percentages.
What the lower end of this table means
Massachusetts has the lowest point estimate, 2.6%. The last three entries are Vermont (3.9%), Hawaii (3.6%), Massachusetts (2.6%) . This ordering is specific to residents without insurance and 2020–2024; it is not a verdict on the state’s overall living conditions.
Rates and counts serve different reporting needs
A percentage compares coverage within each state’s source-defined population. A count describes the scale of residents reporting no insurance. Neither shows how long someone was uninsured, appointment availability, insurance adequacy or the cost of care.
Do not substitute another insurance product silently
ACS estimates and Census SAHIE model-based estimates use different methods and available age groups. An under-65 table cannot be inserted into this all-age ordering under the same label. This snapshot also does not measure a present-day policy effect or diagnose health risks.
Definition, calculation and uncertainty
Uninsured people as a share of the civilian noninstitutionalized population, across all ages. Institutionalized people and active-duty military are outside this universe. Coverage does not establish access to care or personal health.

Source component margins of error are retained in the raw evidence. A derived percentage needs an appropriate uncertainty calculation; adding component margins of error would not provide one. This table orders point estimates without statistical rank intervals. Sorting uses full stored precision. Exact equal values share a position; the next position skips the tied places. A missing, suppressed or unavailable estimate would be excluded and identified rather than converted to zero.
