Why Young Adults Report More Loneliness Than Older Adults

Gallup’s 2023 survey of 142 countries found that 27% of adults aged 19-29 report feeling lonely, against 17% of adults 65 and older. Cigna’s 2020 workplace survey put the gap even wider inside the United States: 73% of workers aged 18-22 reported loneliness, compared with a much lower share among older employees. The Harvard Making Caring Common survey found 61% of young adults aged 18-25 reporting serious loneliness, versus 36% of Americans overall. Every major recent instrument that breaks results out by age finds the same direction. Young people report more loneliness than old people.

This runs against the folk image of aging: the widow alone in an apartment, the retiree with no one to call. That image has some basis — the National Academies estimated in 2020 that roughly one quarter of adults 65 and older are socially isolated, a structural condition distinct from loneliness. But isolation and loneliness are not the same thing, and the surveys that ask people directly whether they feel lonely consistently find the young reporting more of it than the old. The question is why, and there are at least four competing answers, none of which fully displaces the others.

The stigma explanation

The simplest account is measurement, not reality: older adults may be less willing to admit loneliness, having grown up in a cultural moment where doing so read as weakness or failure. If this is right, the gap is partly an artifact of who is comfortable answering an intrusive question honestly, and the true prevalence gap is smaller than surveys show. This explanation is plausible but essentially untestable with self-report data alone — there is no independent check on what a 70-year-old actually feels versus what a 70-year-old is willing to write on a form.

The life-stage explanation

A second account treats the gap as intrinsic to developmental stage rather than cohort or stigma. Young adulthood is a period of repeated network rupture: leaving a hometown, finishing school, changing jobs, ending relationships, moving cities. John Cacioppo’s account of loneliness frames it as an aversive signal that fires precisely when social bonds are unstable or insufficient, and instability is disproportionately concentrated in the twenties. Later life, on this account, brings settled networks — a spouse, a stable friend group, community ties built over decades — even as the network shrinks in absolute size. The AARP Foundation’s 2018 survey of adults 45 and older found that the strongest predictors of loneliness were the size and diversity of a person’s social network and physical isolation, not age itself. Age may simply be a proxy for network stability rather than a cause in its own right.

The cohort explanation

A third account is generational rather than developmental: today’s young adults may be lonelier not because youth is inherently lonely but because this particular cohort has less social infrastructure than earlier cohorts did at the same age. The American Enterprise Institute’s 2021 survey of American friendship found that 12% of Americans report having no close friends, up from 3% in 1990, and that the share of men with six or more close friends fell from 55% in 1990 to 27% in 2021 — a decline concentrated among younger cohorts. If friendship formation itself has become harder across a generation, then today’s 25-year-olds are not simply passing through a universally lonely life stage; they are the first cohort to enter it with thinner networks than their parents had. This explanation predicts that the loneliness gap between young and old should be widening over time, whereas the life-stage explanation predicts it should be roughly constant across decades. The evidence available is not longitudinal enough, across a long enough span, to distinguish the two cleanly.

The pandemic explanation

A fourth account is more recent and more limited in scope. The Harvard survey, fielded in late 2020, found 43% of young adults reporting increased loneliness since the pandemic began, and about half of lonely young adults said no one had taken more than a few minutes recently to ask how they were doing in a way that felt genuine. This suggests at least part of the current gap is a pandemic-era spike layered on top of whatever baseline gap existed before. Gallup’s 2023 data, collected mid-2022 to early 2023, still shows the same age pattern, which argues against a purely transient pandemic effect — but three years of data collected during an unusual period is not enough to establish a stable baseline.

What would resolve this

The honest position is that these four explanations are not mutually exclusive, and the data available cannot cleanly weight them against one another. Doing so would require a long panel study following the same individuals from their twenties into old age, using an instrument like the UCLA Loneliness Scale consistently over decades, with enough sample size to compare across birth cohorts at matched ages. No such dataset yet exists in the sources reviewed here. The BMC Public Health review of the state of the field in 2023 identifies inconsistent measurement across studies as a central barrier to exactly this kind of comparison — researchers cannot easily tell whether a gap is shrinking, growing, or holding steady when the instrument itself changes across surveys.

What can be said with more confidence is that the age pattern is not a quirk of one survey. It recurs across Gallup’s global sample, Cigna’s workplace sample, and Harvard’s US household sample, using different instruments in different years. The 2023 Surgeon General’s advisory treated loneliness as a general population health problem rather than one concentrated at either end of the age range, and the prevalence data available support that framing better than the standard image of the isolated elder does. Older adults face a real and distinct isolation problem, documented by the National Academies. But on loneliness as a felt state, it is the young reporting the most of it, and no single explanation for that has yet been ruled out.
