Health Insurance Statistics (2026)

Most Americans are insured, but a meaningful minority are not. In 2024, about 92.0% of people (310 million) had health insurance for some or all of the year, and 8.0% (27.1 million) had none at any point, per the Census Bureau's Current Population Survey. That is the headline picture behind a system with many moving parts.

Coverage comes from two broad channels: private insurance, which reached 66.1% of the population, and public programs at 35.5%. The two overlap because people move between jobs, ages, and programs during a year, which is why the shares do not sum to 100%.

The long arc has been toward more coverage. Before the Affordable Care Act, the nonelderly uninsured rate sat near 17.8% in 2010 (about 46.5 million people). As the ACA's Medicaid expansion and marketplaces took effect, the rate fell to 10.0% by 2016 and kept drifting down (see the chart below).

By 2023 the nonelderly uninsured rate reached 9.5%, a record low. In 2024 it ticked up for the first time in years, to 9.8% (26.7 million people), as pandemic-era Medicaid protections unwound. The direction of the next few years hinges on subsidy policy.

No single program covers most Americans: coverage is a patchwork. Employer-based insurance is the largest single source at 53.8% of the population, followed by Medicare (19.1%), Medicaid (17.6%), and individually purchased plans at 10.7% (see the chart and table below).

Between 2023 and 2024, private coverage rose 0.7 points while public coverage fell 0.8 points, driven mainly by a 1.3-point drop in Medicaid as pandemic continuous-enrollment rules ended. Medicare, by contrast, kept growing as the population ages.

For working-age Americans, the job is still the front door to health insurance. Employer-sponsored plans cover about 154 million people under 65, more than any government program, a structure that dates to World War II wage controls and the tax exclusion for employer premiums.

That reliance cuts both ways. Coverage is broad and heavily subsidized by employers, but it is also tied to employment: nearly 40% of adults who became uninsured cited a job loss or employer change as the reason, per KFF.

Employer coverage is expensive, and the bill keeps climbing. The average annual premium in 2025 was $9,325 for single coverage and $26,993 for a family, according to KFF's Employer Health Benefits Survey (see the chart and table below). Family premiums rose 6% in a single year.

Zoom out and the trajectory is steep: family premiums have roughly doubled since 2010 ($13,770) and are up 26% over just the last five years, outpacing general inflation of 23.5% over the same window. A family plan now costs about as much as a new economy car.

Workers do not see the full premium, but their share is substantial. In 2025 covered workers contributed on average $1,440 toward single coverage and $6,850 toward family coverage, with employers picking up the rest ($7,885 and $20,143 respectively).

That is money withheld from paychecks before any care is used. Worker contributions to family coverage have risen 23% over five years, and because premiums are pooled, they weigh most heavily on lower-wage workers for whom the fixed dollar amount is a larger share of income.

The premium is only the entry fee: deductibles then decide how much you pay before coverage kicks in. The average single deductible reached $1,886 in 2025, up from $1,617 in 2020, and it runs far higher at small firms ($2,631) than large ones ($1,670) (see the table below).

The spread matters for financial risk. At small firms, 53% of covered workers face a deductible of $2,000 or more, and 72% of all covered workers have an out-of-pocket maximum above $3,000. About 29% are enrolled in HSA-qualified high-deductible plans.

The uninsured are not evenly distributed. In 2024, the nonelderly uninsured rate was 18.4% for Hispanic people and 18.9% for American Indian and Alaska Native people, versus 6.8% for White and 5.7% for Asian people (see the table below). Hispanic people made up 41.9% of the uninsured.

Age matters too: 11.3% of adults 19-64 were uninsured versus 5.9% of children, so adults account for 83.2% of the uninsured. Children fare better largely because Medicaid and CHIP provide a broad public backstop that adults in many states lack.

Being uninsured is overwhelmingly about income and geography, not unemployment. Some 80.2% of the uninsured are in families below 400% of the poverty line, and 85.1% live in working families, per KFF (see the table below). Most uninsured people have a job; the coverage just is not affordable or offered.

Where you live compounds it. The uninsured rate is 14.5% in the states that have not expanded Medicaid versus 8.0% in expansion states, and those non-expansion states hold about 42% of all uninsured people despite being a minority of the population.

When asked directly, the uninsured point to cost first. About 61.7% of uninsured adults said they lacked coverage because it is not affordable, while 28.9% said they were not eligible and 21.0% cited difficulty signing up, per KFF. Among the recently uninsured, 39.7% blamed a job loss or employer change.

The consequences are concrete. Uninsured adults are more than twice as likely to skip or delay care because of cost (38.6% versus 17% for the privately insured), and 62% report some form of medical debt versus 44% of the insured.

The individual market has quietly become a coverage powerhouse. ACA marketplace enrollment hit a record 24.3 million for plan year 2025, up 13% on 2024 and more than double the 11.4 million of 2020, including 3.9 million brand-new consumers (see the table below).

Enhanced premium tax credits, first enacted in 2021 and extended through 2025, are the main engine: they capped premiums as a share of income and made coverage free or near-free for many lower-income enrollees, pulling millions off the sidelines.

That momentum now faces a reversal. The enhanced premium tax credits expired at the end of 2025, and KFF estimates the change raises marketplace premium payments by about 114% on average, roughly $1,016 a year, for subsidized enrollees. CBO projects the uninsured population rising as a result.

Estimates vary but point the same way: analyses suggest millions could lose marketplace coverage in 2026, with average effectuated enrollment potentially falling from about 22.3 million in 2025 toward 17.5 million or lower. These are projections, not settled outcomes, and depend on whether Congress acts.

Underneath all of this is an enormous spending machine. The US spent $4.9 trillion on health care in 2023, about $14,570 per person and 17.6% of GDP, and spending grew 7.5% that year as coverage and utilization rose, per CMS National Health Expenditure data.

That share of the economy is far above other wealthy nations and helps explain why premiums and deductibles climb faster than wages. Health costs are ultimately what insurance premiums are pricing, so cost growth and coverage affordability are two sides of the same coin.

Health insurance is one of the largest line items in most household budgets, whether you see it as a payroll deduction or a marketplace premium. Understanding your true exposure means looking past the premium to the deductible and out-of-pocket maximum, which is where a bad year actually hits.

For investors, health costs are also a planning input: medical expenses are a leading driver of financial stress and debt, and a fully-funded emergency reserve plus an HSA (if you are in a high-deductible plan) are the standard defenses. An HSA is triple-tax-advantaged and can double as a long-term investing account once near-term medical needs are covered.
