Americans aged 65 and older made up 18.9% of the US population in 2025, roughly 64.6 million people, with that share projected to climb to 23.4% by 2060. A 65-year-old American in 2024 could expect to live another 19.7 years on average, even as more than 90% of seniors live with at least one chronic health condition and 70% of people turning 65 will eventually need some form of long-term care.
Aging Population in America 2026 – Introduction
The aging US population represents one of the most consequential demographic shifts the country is currently navigating, reshaping everything from Medicare and Social Security solvency to housing design and the long-term care workforce. The underlying math is straightforward: Americans are living longer than previous generations while birth rates have fallen well below replacement level, meaning the share of the population in retirement age keeps growing even as the working-age population that funds entitlement programs grows more slowly. What was once a distant policy concern has become a present-day planning challenge, with seniors now the fastest-growing major age group in the country.
2026 finds this shift accelerating as the last of the large Baby Boomer generation crosses into traditional retirement age, pushing the senior population toward levels the US has never experienced. The implications extend well beyond pure demographics: healthcare spending concentrates heavily among the oldest Americans, long-term care costs continue outpacing household income growth, and an increasing number of states now have more residents over 65 than children under 18. This report breaks down exactly how large America’s senior population has become, how long today’s older Americans can expect to live, and what their healthcare and long-term care needs look like heading into the back half of the decade.

The scale of America’s aging population becomes clearest when placed against its own recent history: seniors made up just 8% of the US population in 1950, meaning the current 18.9% share represents more than a doubling of the senior population’s relative size in just over 70 years. That trajectory shows no sign of leveling off — by 2040, researchers project the 65-and-older population will reach roughly 78 to 80 million people, and by 2060, nearly 1 in 4 Americans is expected to be 65 or older, a milestone that would fundamentally reshape the dependency ratio between working-age Americans and retirees that funds Social Security and Medicare.
Perhaps the most striking single fact in the 2026 data is how healthy and independent today’s seniors remain relative to perceptions of aging in prior decades, even as chronic conditions remain nearly universal. Life expectancy at age 65 climbed to 19.7 years in 2024, about two months longer than in 2023, meaning the average 65-year-old American today can expect to live well into their mid-80s. That combination — longer lives paired with near-universal chronic disease management — is precisely what has made eldercare policy, housing, and workforce planning such a central focus of public debate in 2026.

The US senior population reached an estimated 64.6 million people in 2025, based on the Census Bureau’s July 2025 total population estimate of 341.8 million, with adults 65 and older making up 18.9% of all Americans. Separate 2026-specific estimates place the figure slightly higher, around 19.2%, reflecting the ongoing wave of Baby Boomers continuing to age into the 65-plus bracket each year. Within that broader group, the age 75-and-older population stood at roughly 22.2 million (6.7% of all Americans), and the 85-and-older population — the fastest-growing segment within the senior population itself — reached nearly 6 million, or 1.8% of the total US population.
That growth trajectory places the United States in a notable position globally: as of 2025, the US ranked just 48th among 227 countries by the age of its population, meaning dozens of other nations, particularly in Europe and East Asia, have already aged considerably further than the US has. Still, the US trend line points firmly upward, with the senior population projected to climb from roughly 64.6 million today to somewhere between 78 and 80 million by 2040, and to represent nearly a quarter of the entire country by 2060.

A 65-year-old American in 2024 could expect to live another 19.7 years on average, roughly two months longer than the equivalent figure for 2023 — a modest but meaningful continuation of the post-pandemic recovery in US life expectancy. That additional-years-at-65 figure differs from overall life expectancy at birth, which stood at 78.4 years in 2025, because it specifically measures remaining years for people who have already survived to age 65, a population that, by definition, has already avoided many of the causes of earlier mortality that pull down the birth-year average.
The familiar gender gap in life expectancy persists clearly among older Americans as well: men’s life expectancy at birth stood at 75.8 years compared with 81.1 years for women, a 5.3-year gap that, while still substantial, has been narrowing gradually in recent years as male life expectancy has recovered somewhat faster than female life expectancy from pandemic-era declines. That gender gap also shows up directly in the demographic composition of the oldest Americans: women make up roughly 55% of the 65-and-older population and nearly 64% of Americans 85 and older, reflecting their statistically longer average lifespans.

Chronic health conditions are effectively universal among older Americans: more than 90% of adults 65 and older, and over 75% of adults aged 35 to 64, live with at least one chronic health condition, according to CDC data — a reminder that chronic disease management, not acute illness, dominates most older Americans’ ongoing healthcare needs. That reality is precisely why Medicare enrollment runs so near-universal among seniors, with 98.2% of Americans 65 and older enrolled in the program, by far the dominant source of health coverage for this age group.
Despite that near-universal Medicare enrollment, a substantial share of seniors maintain additional coverage to fill gaps Medicare doesn’t address: 23.4% carry supplemental private insurance (often Medigap or employer retiree coverage), 14.1% qualify for supplemental Medicaid coverage (typically lower-income or disabled seniors), and altogether 35.5% of seniors maintain multiple types of coverage simultaneously — a pattern that reflects how Original Medicare’s lack of an out-of-pocket maximum and limited long-term care coverage pushes many older Americans toward supplemental insurance despite the program’s broad base. Medicare’s hospital cost-sharing structure also directly shapes seniors’ financial exposure: the Part A inpatient deductible reached $1,736 per benefit period in 2026, with daily coinsurance charges applying to extended hospital stays. For more detail on how these Medicare cost-sharing rules affect older Americans’ hospital bills specifically, see our Average Hospital Bill Statistics in US report.

Long-term care represents one of the largest and least-planned-for financial exposures facing older Americans, with an estimated 70% of people turning 65 expected to need some form of long-term care during their remaining lifetime, for an average duration of roughly 3.1 years. The financial scale of that need is considerable: HHS research estimates the average lifetime cost of long-term support services at $135,000 to $138,000 per person, while a private nursing home room now runs as high as $11,294 a month nationally as of 2026 — more than $135,000 annually — with costs varying enormously by state, ranging from roughly $190 a day in parts of the South to over $1,000 a day in Alaska.
Because Medicare covers only short-term skilled nursing care following a qualifying hospital stay — generally capped at 100 days, with significant coinsurance after day 20 — the burden of paying for longer-term custodial care falls heavily on Medicaid, which now covers roughly 60% to 62% of all nursing home residents nationally, and on families themselves, who collectively absorb an estimated 37% of total long-term care costs out of pocket, with about 14% of seniors spending more than $100,000 out of pocket over their lifetime. Beyond paid facility care, an estimated 63 million family caregivers across the US provide unpaid support to aging relatives, a workforce roughly five times larger than the entire US nursing profession, underscoring just how much of America’s eldercare system still runs on informal, unpaid family labor rather than formal paid care arrangements.
Where Seniors Live and Demographic Shifts in 2026

| Lowest-share state for 65+ population | Utah (~12.4%) |
| Projected 65+ population by 2100 | Nearly 96 million (up from ~56 million in 2022) |
Data Source: America’s Health Rankings, US Census Bureau
The geographic distribution of America’s aging population varies dramatically by state, with Maine carrying the nation’s highest senior share at roughly 23.5% of its population, compared with just 12.4% in Utah, a gap reflecting differences in birth rates, retiree migration patterns, and the age structure of each state’s existing population. More strikingly, 11 US states have now crossed a genuine demographic threshold where residents 65 and older actually outnumber children under 18 — a milestone that, as recently as a generation ago, would have been difficult to imagine for any US state outside of a handful of retirement-heavy regions like Florida.
Looking further out, the Census Bureau’s longer-range projections suggest the senior population will nearly double again by 2100, climbing from roughly 56 million in 2022 toward almost 96 million by the turn of the next century, even as urban areas — home to 47.4 million seniors already, though they represent just 16.4% of the total urban population — continue absorbing a growing share of that aging cohort. That combination of a shrinking youth population relative to a growing senior population across an increasing number of states represents one of the clearest and most consequential demographic throughlines shaping US policy debates heading into the later 2020s and beyond.
