About 27.2 million people in the USA were uninsured in 2024, which corresponds to an uninsured rate of about 8.2%.
Those counts typically come from U.S. survey tracking of health coverage and are commonly reported as the number of people without insurance at any point in the reference period.
Insurance gaps have been changing since the pandemic era, with recent reporting indicating the uninsured population and share increased in 2024 after a period of declines.
In practical terms, the "how many" question depends on what you treat as uninsured (for example, all ages vs. working-age adults, and whether noncitizens are handled differently), but national headline figures generally cluster around the high-20-millions.
- 2024 uninsured: 27.2 million Americans (8.2%).
- Trend note: Coverage gaps reportedly widened in 2024, increasing for the first time since 2019, based on analyses of American Community Survey data.
- Regional pattern: Uninsured rates differ notably between Medicaid expansion and non-expansion states.
How many are uninsured in the US?
The most-cited national headline for the uninsured population is that 27.2 million Americans lacked health insurance in 2024.
That figure implies an uninsured share of about 8.2% of the population for the same year.
For policy analysis, you can also use a rate to compare across years, because population growth can change "how many" even if the percentage stays relatively stable.
| Year | Uninsured people (millions) | Uninsured rate | What to watch |
|---|---|---|---|
| 2023 | ~26.4 | ~8.0% | Coverage had been improving earlier in the decade. |
| 2024 | 27.2 | 8.2% | Number and share reportedly grew in 2024 (reversing earlier improvements). |
| 2025 | ~28.6 | 8.5% | Some secondary reporting suggests further increases, but confirm with official datasets for precision. |
What's driving the US coverage gap?
Cost is a central reason people go without coverage, and in recent analyses a large share of the uninsured report affordability as the main barrier.
Another driver is eligibility and program design-especially differences between states that expanded Medicaid and those that did not, which can leave some low-income adults with fewer affordable paths to coverage.
When policies change enrollment stability-such as the ending of certain pandemic-era coverage boosts-uninsured rates can move upward again, even if the country's longer-run direction had been improving.
"The number and share of people without insurance grew in 2024, increasing for the first time since 2019."
Who is most likely to be uninsured?
Uninsurance is not evenly distributed: working-age adults and certain demographic groups show higher uninsured rates than the overall population.
One reported breakdown shows working-age adults uninsured at 11.6% in 2024, alongside an overall uninsured rate of 8.2%.
Children are generally lower than adults in uninsured rates, but the total count can still be meaningful because child enrollment is large and coverage churn exists.
- Children uninsured: 5.1% (2024).
- Working-age adult uninsured: 11.6% (2024).
- Overall uninsured: 8.2% (2024), 27.2 million people.
Medicaid expansion and regional differences
Medicaid expansion status appears closely linked to the uninsured rate, with higher uninsured shares reported in non-expansion states compared with expansion states.
For 2024, one reported set of regional figures shows non-expansion states at 17.4% uninsured versus expansion states at 9.3%.
These gaps create a "coverage geography" effect: people's insurance outcomes can be strongly influenced by where they live, not just by income.
Latest trends: what changed recently?
2024 stands out in recent reporting because multiple analyses indicate the uninsured count and share increased after earlier improvements.
One discussion of trends notes that the uninsured rate reached a level around 8% in 2024 and that the uninsured population increased year-over-year.
From a historical perspective, that means the post-2019 period that saw improvement in coverage can be interrupted by policy and enrollment shifts, underscoring why "how many" must be updated frequently rather than assumed.
- Track the national uninsured count and rate using major survey-based reporting.
- Check whether 2024 shows an upward break versus recent years-some analyses report it did.
- Segment by age and state Medicaid policy to explain why the change occurred.
How to interpret "uninsured" numbers
Measurement matters: survey instruments can classify people as uninsured depending on the reference period, the definitions used, and whether the person had any coverage at all during that window.
As a result, two reports may quote slightly different numbers even when they refer to the "same year," because of differences in modeling, subgroup handling, and whether they focus on particular populations.
If you're writing or reporting on the issue, you'll usually want to cite both the uninsured count and uninsured rate, because the rate is easier to compare across years.
What this means for policy and coverage access
Coverage policy aims to reduce uninsured rates by improving affordability and eligibility pathways-so the numbers are not just statistics; they reflect how effectively systems connect people to care.
Because costs and eligibility rules remain persistent barriers, the uninsured share can rise even when other parts of the coverage system are stable.
For ongoing updates, many analysts recommend tracking year-by-year uninsured counts and rates alongside enrollment/eligibility policy changes that can shift participation and re-enrollment.
Illustrative example: turning a national number into impact
Population scale can make the coverage gap feel abstract, so here's a concrete way to interpret the 2024 figure: if you imagine a "snapshot" of a large metropolitan area at the same uninsured rate, roughly 8 in every 100 people would be uninsured on the reporting basis used for national estimates.
At 27.2 million, that translates into a large enough population that missed screenings, delayed care, and financial stress are likely to be widespread-especially among groups with higher uninsured rates like working-age adults.
If you want, I can also produce a state-by-state breakdown (or a working-age vs. child view) using the most recent published datasets-but I'll need you to confirm whether you prefer ACS-based estimates or other official sources for your article's citations.
