Just over a quarter of people aged 65-74 in France lived alone in 2021, rising to nearly one in two at ages 90-94 (Insee).

The share of people living alone climbs with every five years of age until the mid-eighties, when it levels off or dips, not because people stop being alone but because more of them move into care. In the oldest bands the figures are startling: more than half of Germans over 85, two thirds of Finnish women at 90, nearly half of Aucklanders over 90.

Worldwide, 24% of women aged 65 and over lived alone in 2006-2015, more than twice the share of men the same age (11%) - UN DESA's harmonised estimate across countries with data.

Two to one, in every country with data, because women outlive their husbands. The gap is closing from both ends: men are living longer, so fewer women are widowed young, and more men are reaching old age unmarried. In the UK the number of men over 75 living alone has more than doubled since 1996; in the EU single men over 65 grew more than twice as fast as single women over the last decade.

54.25% of people aged 65 and over in private households in Lithuania lived alone (2024; rank 1 of 39 countries in the OECD Affordable Housing Database HM1.4, 2025 update).

The Baltic states and the Nordic countries top every ranking; southern and eastern Europe, Latin America and Asia sit at the bottom; the United States is in the middle of the rich world. The pattern follows widowhood, housing and whether grown children stay: where extended families are the norm, almost nobody old lives alone.

26% of U.S. adults aged 65 and over lived alone in 2023, down from 29% in 1990 (Pew Research Center analysis of Census Bureau data, December 2025).

Both headlines you have read are true. In the United States, the share of older adults living alone peaked around 1990 and has drifted down since, mostly because more older women now have a living husband; the number keeps rising because the older population is growing so fast. Canada's share has barely moved in forty years while its count more than doubled. In Japan, Korea, Singapore and most of Europe both share and count are still climbing.

By 2050 one in five Japanese households (20.6%) will be a person aged 65+ living alone; 32 prefectures exceed 20%, led by Kochi (27.0%), Tokushima (25.3%) and Ehime (24.9%).

Japan and South Korea publish the projections everyone else lacks, and they point the same way: older people living alone become the single most common household type. The United States has only a projection for the over-80s, the Netherlands and England for the next decade. No official projection of the number of people aged 65 and over living alone exists for the United States, the United Kingdom or the EU as a whole; the nearest proxies are below.

Widows were 29% of all U.S. women aged 65 and over in 2023 - 9 million people, more than three times the 2.9 million widowers (ACL, 2023 Profile of Older Americans; CPS ASEC).

Mostly widows, increasingly never-married men, and a growing minority with no close family at all. Two terms get mixed up here: living alone (a household of one, any age, any family ties) and solo agers, AARP's label for people over 50 who live alone with no partner and no living children. About one in eight older Americans is a solo ager; most people living alone have children somewhere.

Overwhelmingly, people want to stay in their own homes and, given the choice, to live on their own. What they lack is not the wish but the backup: only a third of solo agers have someone who could run their household if they were ill, a quarter of older Norwegians living alone have no family within half an hour, and the ratio of potential family carers to people over 80 is falling fast.

• Among 1,306 French patients aged 75+ admitted via emergency departments, 45% of those who lived alone did not feel lonely, while 34% of those who lived with others did feel lonely; living alone was associated with longer, not shorter, survival (Simo et al., Gériatrie et Psychologie Neuropsychiatrie du Vieillissement, 2025).
• 92.8% of Italians aged 75+ living alone say they can count on relatives, 69.2% on neighbours and 58.9% on friends; 3.2% have none of these (Istat 2023).

• An estimated 2 million people aged 65+ in England have unmet needs for care and support, including hundreds of thousands unable to complete three or more activities of daily living who receive no help or inadequate help (Age UK analysis of ELSA Wave 10, 2021-23; State of Health and Care of Older People in England 2025).
• One in five (20.7%, about 629,000) Americans aged 70+ who needed help with daily activities reported receiving inadequate assistance in 1994; living alone was one of three factors linked to unmet need, and nearly half of those with unmet needs suffered a consequence such as being unable to eat when hungry (Desai, Lentzner & Weeks, The Gerontologist, 2001).
• 32% of older Americans who had difficulty with or received help for daily activities (outside nursing homes) experienced an adverse consequence from an unmet need in the past month, rising to nearly 60% among community residents with a paid caregiver (Freedman & Spillman, Milbank Quarterly, 2014; NHATS 2011).
• About 31,000 Israelis aged 65+ live with a non-relative, usually a live-in caregiver - about 10% of seniors in non-family households, down from 12% in 2022 and 13% in 2021.
• Only 67,003 older people were on Taiwan's local-government registers of 'elderly living alone needing care' at end-2025 (27,583 men, 39,420 women), about 1.4% of the 65+ population, versus 25.8% actually registered as living alone.

Among older adults, living alone was associated with a 21% higher risk of all-cause death (hazard ratio 1.21, 95% CI 1.13-1.30) in a meta-analysis of 86 prospective studies (Nakou et al., Aging Clinical and Experimental Research, 2025).

Living alone is a risk factor of about the same size as the loneliness and social isolation it is often confused with, and the three are not the same thing. A person can live alone and be surrounded by friends; a person can live with family and be isolated. The table collects the effect sizes with their confidence intervals so they can be quoted correctly, and the list below keeps the three exposures apart.

• Living alone was associated with a 32% higher likelihood of death (odds ratio 1.32) across 70 prospective studies with 3,407,134 participants followed for an average of 7 years (Holt-Lunstad et al., Perspectives on Psychological Science, 2015).
• Objective social isolation was associated with a 29% higher likelihood of death (odds ratio 1.29) in the same 70-study, 3.4-million-participant meta-analysis (Holt-Lunstad et al., 2015).
• Loneliness (the subjective feeling) was associated with a 26% higher likelihood of death (odds ratio 1.26) in the 70-study meta-analysis, the smallest of the three social-deficit effects (Holt-Lunstad et al., 2015).
• Social isolation carried a 35% higher risk of death in older adults (hazard ratio 1.35, 95% CI 1.27-1.43) across 86 studies, a larger effect than loneliness (HR 1.14) or living alone (HR 1.21) (Nakou et al., 2025).
• Social isolation was associated with a 32% higher risk of all-cause mortality (pooled effect size 1.32, 95% CI 1.26-1.39) across 90 prospective cohort studies with 2,205,199 participants (Wang et al., Nature Human Behaviour, 2023).
• Loneliness was associated with a 14% higher risk of all-cause mortality (pooled effect size 1.14, 95% CI 1.08-1.20), less than half the excess seen for social isolation, in the 90-cohort meta-analysis (Wang et al., 2023).
• Social isolation raised the risk of cardiovascular death by 34% (pooled effect size 1.34, 95% CI 1.25-1.44) in the 90-cohort meta-analysis (Wang et al., 2023).
• A GRADE-rated meta-analysis of 18 cohorts (62,174 adults) found living alone raised all-cause mortality by 15% overall (RR 1.15, 95% CI 1.08-1.23), but the excess was confined to younger adults (RR 1.41) and absent in older adults (RR 1.05, 95% CI 0.91-1.22) (Zhao et al., EClinicalMedicine, 2022).
• In the 2010 meta-analysis, a simple yes/no measure of living alone was the weakest social predictor of mortality (odds ratio 1.19, 95% CI 0.99-1.44, 17 studies), versus 1.91 for complex measures of social integration (Holt-Lunstad et al., 2010).
• People with stronger social relationships had a 50% higher likelihood of survival (odds ratio 1.50, 95% CI 1.42-1.59) across 148 studies and 308,849 participants followed for an average of 7.5 years (Holt-Lunstad, Smith & Layton, PLoS Medicine, 2010).
• In the English Longitudinal Study of Ageing (4,888 people followed 8.5 years), living alone was associated with a 20% higher risk of death (HR 1.20, 95% CI 1.04-1.38) after adjusting for wealth, health, behaviours and loneliness (Abell & Steptoe, Age and Ageing, 2021).
• ELSA participants who moved to living alone after divorce or bereavement had a 34% higher mortality risk (HR 1.34, 95% CI 1.01-1.79) than those who lived with others throughout; those who began living alone for other reasons showed no excess risk (Abell & Steptoe, 2021).
• In UK Biobank (458,146 adults, 12.6-year follow-up), people who lived alone and never had friends or family visit had 77% higher all-cause mortality (HR 1.77, 95% CI 1.61-1.95) than those with daily visits who did not live alone; living alone with daily visits still carried HR 1.19.
• Socially isolated UK Biobank participants (466,901 adults, mean age 56.5) had a 26% higher all-cause mortality risk after full adjustment (HR 1.26, 95% CI 1.20-1.33; minimally adjusted 1.73), whereas loneliness lost significance after adjustment (HR 0.99).
• Among people with established cardiovascular disease, living alone was associated with a 48% higher risk of all-cause death (HR 1.48, 95% CI 1.20-1.83; 15 studies, 80,243 patients) (Long et al., Psychosomatic Medicine, 2023).
• Cancer patients living alone had a 22% higher risk of death from any cause (HR 1.22, 95% CI 1.13-1.32) in a meta-analysis of 21 cohorts covering 2,497,397 patients (Huang et al., Frontiers in Oncology, 2026).
• Older Singaporeans living alone had a 66% higher risk of death over 8 years than those living with others (HR 1.66, 95% CI 1.05–2.63), rising to HR 2.36 for men, Singapore Longitudinal Ageing Studies (2,553 Chinese adults aged 55+, 7.4% living alone).
• Older Japanese men who both lived alone and ate alone had a 19% higher 3-year mortality risk than men who ate with others (HR 1.19, 95% CI 1.01–1.41); men who ate alone despite living with others fared worse (HR 1.48), JAGES cohort, 33,083 men and 38,698 women aged 65+.
• Contrary to most cohorts, Chinese older adults living alone had 15% lower all-cause mortality than those living with family (HR 0.85, 95% CI 0.76–0.95) in a propensity-matched CLHLS analysis of 7,963 people (2014–2018).
• Living alone was associated with a 30% higher risk of incident dementia (pooled RR 1.30, 95% CI 1.15-1.46) across 12 longitudinal studies, with a population attributable fraction of 8.9% using UK Census prevalence (Desai et al., Ageing Research Reviews, 2020).
• The 2020 Lancet Commission put the relative risk of dementia from later-life social isolation at 1.6 (95% CI 1.3-1.9) with a weighted population attributable fraction of 3.5%, one of 12 modifiable factors accounting for around 40% of dementias (Livingston et al., The Lancet, 2020).
• The 2024 Lancet standing Commission estimates that 14 modifiable risk factors, including social isolation, together account for 45.3% of dementia cases worldwide (Livingston et al., The Lancet, 2024).
• In 462,619 UK Biobank participants followed for a mean 11.7 years, social isolation was associated with a 26% higher risk of dementia (HR 1.26, 95% CI 1.15-1.37) independent of loneliness and depression, whereas loneliness itself was not (HR 1.04) (Shen et al., Neurology, 2022).
• Among 155,070 UK Biobank participants followed 8.8 years, socially isolated people had a 62% higher risk of dementia (HR 1.62, 95% CI 1.38-1.90) at every level of genetic risk, while loneliness was not associated with dementia (Elovainio et al., BMJ Open, 2022).
• In the French MEMENTO memory-clinic cohort (2,269 people, median age 71.5), living alone did not raise dementia risk (HR 0.88) but tripled the risk of moving into an institution over five years (HR 3.21, 95% CI 1.09-9.48) (Huvent-Grelle et al., Frontiers in Aging, 2026).
• People living alone had 42% higher odds of developing depression (pooled OR 1.42, 95% CI 1.19-1.70) in a meta-analysis of seven longitudinal studies covering 123,859 people without prior psychiatric history (Wu, Liu & Huang, Frontiers in Psychiatry, 2022).
• 16.1% of South Korean elders living alone had depressive symptoms versus 7.8% of those living as a couple; only 34.2% of those living alone rated themselves healthy versus 48.6% of couples (2023 National Survey of Older Koreans).
• Chinese adults aged 60+ who lived alone had 33% higher odds of depressive symptoms than those living with others (OR 1.33, 95% CI 1.14–1.54; 5,311 participants), and the risk was concentrated in those with low financial support (cohort OR 1.83), CHARLS 2015–2018.
• Older Japanese men living alone had 43% higher odds of developing depressive symptoms over 2.6 years than men living with a spouse only (OR 1.43, 95% CI 1.18–1.73); no significant association in women, JAGES, 19,656 men and 22,513 women aged 65+.
• Singaporeans aged 60+ who live alone were twice as likely to report depressive symptoms as those who do not (Duke-NUS Centre for Ageing Research and Education, cited by MOH, January 2026).
• Lonely older adults were more likely to die within six years (22.8% vs 14.2%; adjusted HR 1.45, 95% CI 1.11-1.88) and to lose ability in daily activities (24.8% vs 12.5%; adjusted RR 1.59) (Perissinotto et al., 2012).
• Poor social relationships (social isolation or loneliness) are associated with a 29 percent higher risk of incident coronary heart disease and a 32 percent higher risk of stroke, according to the National Academies' review citing Valtorta et al. 2016 (NASEM, 2020).
• Among Chinese adults over 65 living alone, often feeling lonely doubled the risk of new cardiovascular disease (HR 2.17, 95% CI 1.20-3.93) compared with never feeling lonely; loneliness overall raised CVD risk 28% (HR 1.28) while living alone per se showed no association (Tan et al., Journals of Gerontology A, 2024).
• In 4,144 older Tokyo residents followed a median 96 months, social isolation (infrequent contact with others) more than doubled cardiovascular mortality (HR 2.20, 95% CI 1.43-3.39), while living alone by itself did not (HR 0.88, 95% CI 0.52-1.49) (Imamura et al., Maturitas, 2026).
• 32.2% of community-dwelling older men living alone in a South Korean cohort (n = 230, aged 65+) were malnourished on the Mini Nutritional Assessment-Short Form; meal skipping tripled the odds (OR 3.26) (Kim et al., Nutrition Research and Practice, 2024).
• Older adults reported to social services for self-neglect had nearly six times the risk of dying within a year (HR 5.82, 95% CI 5.20-6.51) in the Chicago Health and Aging Project (9,318 people aged 65+, 1993-2005) (Dong et al., JAMA, 2009).
• Social isolation among older adults is associated with an estimated $6.7 billion in additional Medicare spending each year, based on 5,270 Health and Retirement Study participants linked to Medicare claims 2006-2012 (Flowers et al., AARP Public Policy Institute, 2017).

Loneliness and isolation

The National Academies' 2020 consensus report states that approximately one-quarter (24 percent) of community-dwelling Americans aged 65 and older are socially isolated, and that 43 percent of adults aged 60 and older report feeling lonely (NASEM, 2020).

• In 2011, 24% of community-dwelling Americans aged 65 and over, about 7.7 million people, were socially isolated, including 1.3 million (4%) who were severely isolated, by a typology combining living arrangement, discussion network, religious attendance and social participation (Cudjoe et al., Journals of Gerontology B, 2020).
• 43% of US adults over 60 reported feeling lonely in the 2002 Health and Retirement Study psychosocial module, although only 18% lived alone (Perissinotto, Stijacic Cenzer & Covinsky, Archives of Internal Medicine, 2012).
• One in six people worldwide is affected by loneliness, which the WHO Commission on Social Connection links to more than 871,000 deaths a year, about 100 every hour (WHO, From loneliness to social connection, 30 June 2025).
• Social isolation affects up to 1 in 3 older adults and 1 in 4 adolescents worldwide, according to the WHO Commission on Social Connection (WHO, 2025).

Stroke patients who lived alone were far less likely to reach hospital within 2.5 hours of symptom onset: 28.3% versus 40.0% of those living with others (adjusted OR 0.54, 95% CI 0.48-0.60), among 10,048 patients in the Registry of the Canadian Stroke Network 2003-2008 (Reeves et al., Stroke, 2014).

This is where living alone stops being a demographic fact and becomes a clinical one. Strokes are treated later and worse; falls are more likely and more likely to end on the floor; people found helpless at home die far more often when they have been down for days than when they are found within the hour; and in Japan, the only country that counts, tens of thousands of people who lived alone are found days or weeks after they died. Every figure here is also on our statistics page on falls and the long lie, which goes deeper on what happens on the floor.

• After a heart attack treated with PCI, patients living alone (30% of 277) died at more than twice the rate of those living with others (18% vs 8% all-cause; 14% vs 4% cardiac), with adjusted hazard ratios of 2.60 for all-cause and 4.17 for cardiac death (Fukumoto et al., Coronary Artery Disease, 2023).
• Men living alone after a first acute heart-failure admission had twice the risk of being rehospitalised for heart failure over three years (adjusted HR 2.02, 95% CI 1.07-3.70); no difference was seen in women (HR 0.99) (Takabayashi et al., International Heart Journal, 2020).

• Of 387 episodes of people living alone being found helpless or dead at home in San Francisco in 1993, 23% were found dead and a further 5% died in hospital, a total mortality of 28% (Gurley et al., NEJM, 1996).
• In a 12-week population-based study in San Francisco (1993), paramedics found 367 people living alone helpless or dead at home (387 events); 23% were found dead and a further 5% died in hospital, total mortality 28%.

• In the US Health and Retirement Study (2012-2020, n = 1,893), poorly maintained stairways (OR 2.65) and nearby green space (OR 2.10) raised the odds of falling over eight years only among older adults living alone, not among those living with others (Lee & Lim, Innovation in Aging, 2023).
• Norwegian hip-fracture patients aged 50-79 who lived alone had higher mortality over 12.8 years than those living with a partner: HR 1.37 (95% CI 1.29-1.44) for men and 1.23 (1.18-1.28) for women, among 12,770 men and 22,067 women fractured 2002-2013 (Dahl et al., Journal of Bone and Mineral Research, 2021).
• Eight years after a hip fracture, relative survival (vs the general population) was 43% for men and 61% for women who lived alone, compared with 51% and 67% for those living with a partner (Dahl et al., 2021).
• In a London case-control study, 79% of patients admitted with hypothermia after being found ill indoors (mean age 80) had been found on the floor, versus 14% of controls; 86% lived alone (vs 43%) (Woodhouse, Keatinge & Coleshaw, The Lancet, 1989).
• During the July 1995 Chicago heat wave (at least 700 excess deaths), people who lived alone had 2.3 times the odds of heat-related death; in multivariate analysis living alone (OR 2.3) and being confined to bed (OR 8.2) were the strongest risk factors, while a working air conditioner cut the risk by 70% (OR 0.3) (Semenza et al., NEJM, 1996).

• In Stockholm's SNAC-K cohort (3,130 older adults, 56.5% living alone), living alone was associated with a 21% higher risk of an unplanned hospital admission over two years (HR 1.21, 95% CI 1.01-1.45) and 35% more admissions (IRR 1.35); among men the hazard was 1.52 (Pimouguet et al., European Journal of Public Health, 2017).
• Hospital patients aged 50+ who lived alone had more than twice the odds of being discharged to a skilled nursing facility rather than home (adjusted OR 2.23, 95% CI 1.85-2.69), even at similar clinical and functional status, in 7,029 medical admissions at Massachusetts General Hospital 2014-15 (Lage et al., Journal of the American Geriatrics Society, 2018).
• After elective hip replacement, 22.0% of patients living alone were discharged somewhere other than home versus 10.5% of propensity-matched patients with others at home (adjusted OR 2.84, 95% CI 2.30-3.54), with longer stays (2.05 vs 1.72 days) in 2021 US NSQIP data (Agnor, Knio & Zuo, PLoS ONE, 2025).
• Older patients receiving home nursing after a medical hospitalisation who were ADL-dependent and lived alone were 3.5 times more likely to enter a nursing home within a month (95% CI 1.0-11.9) and 3.3 times less likely to regain function than those living with others (Mahoney et al., Journal of General Internal Medicine, 2000).
• 21% of people aged 65+ who live alone visit their GP at least once a month, compared with 14% of older people who live with others (Dreyer et al. 2018, as compiled by Age UK).
• Patients aged 65+ living alone had 50% higher odds of using emergency department services (OR 1.50, 95% CI 1.16-1.93) and 40% higher odds of GP use (OR 1.40, 1.04-1.88) than those living with others - London general-practice cohort of 1,447 patients.
• 32% of older Norwegians living alone receive at least one municipal health or care service, versus 10% of those living with a partner (SSB, 2025).
