Living Alone in Australia: Statistics on Seniors, Risk and Discovery Time
Roughly 1 in 4 Australians aged 65 and over live alone, rising to about 35% of those aged 85 and over (ABS / AIHW). Most are women, and the defining risk is the discovery gap when something goes wrong at home.

Overview: how many older Australians live alone
About 25% of Australians aged 65 and over live alone, and the share rises to roughly 35% of those aged 85 and over (ABS / AIHW). The oldest age band is the most likely to live by itself. The majority of older Australians who live alone are women. At the 2016 Census about 31% of older women lived alone versus 18% of older men, widening to 35.1% of women versus 19.0% of men in the 2022 ABS Survey of Disability, Ageing and Carers (ABS SDAC, 2022). Living alone is not, in itself, dangerous. What changes the odds is the discovery gap: when something goes wrong, there may be no one in the home to notice for hours, or in the worst cases days.
Key statistics at a glance
These are the verified, directly sourced figures behind the living-alone picture in Australia. The headline living-alone shares come from the ABS and AIHW, the fall figures from AIHW falls reporting, carer and loneliness figures from the ABS SDAC and AIHW/HILDA, and the long-lie mortality figure from a peer-reviewed cohort corroborated by Age UK.
Living alone among older Australians, by age and sex
Living alone climbs sharply with age, and at every measured point older women live alone at close to twice the rate of older men. The headline shares are the published ABS / AIHW figures of about 25% for all 65+ and about 35% for the 85+ band. The sex split is measured directly by the ABS across two instruments and is consistent and slightly widening over time, from a 31% versus 18% gap at the 2016 Census to 35.1% versus 19.0% in the 2022 ABS Survey of Disability, Ageing and Carers.
Living alone among older Australians: verified ABS / AIHW figures
| Group | Share living alone | Source |
|---|---|---|
| All Australians 65+ | ~25% | ABS / AIHW |
| Australians 85+ | ~35% | ABS / AIHW |
| Older women (2016 Census) | 31% | ABS Census 2016 |
| Older men (2016 Census) | 18% | ABS Census 2016 |

Headline shares are ABS / AIHW published figures; the women-vs-men splits are directly measured by the ABS at the 2016 Census and in the 2022 Survey of Disability, Ageing and Carers.
Living alone is concentrated in the oldest, most fall-prone Australians
The share living alone is roughly 25% across all 65+ but climbs to about 35% among the 85+ (ABS / AIHW). That same 85+ group is, on a per-person basis, the most likely to be hospitalised for a fall. Older Australians overall are about 12 times as likely to be hospitalised for a fall as adults aged 25 to 44 (AIHW, 2023-24). The two curves point the same way: the people most likely to live without a witness are the people most likely to need one.
The risk is structurally female
Because women live longer and are more likely to outlive a partner, the typical older Australian living alone is a woman in her late 70s or 80s. The data is consistent across instruments and widening over time, from 31% of older women versus 18% of older men at the 2016 Census to 35.1% versus 19.0% in the 2022 SDAC (ABS, 2016 / 2022). In practice, any safety planning for older Australians is planning for older women living alone.
The decisive variable is time-to-discovery, not the incident itself
Falls happen at home in 53% of hospitalised cases among older Australians (AIHW, 2019-20). When someone lives with a partner or family, a collapse is usually witnessed in minutes and triple zero (000) is called immediately. When someone lives alone, the same event may not be noticed until a scheduled call, a visit, a missed appointment, or a neighbour spots something. The clearest evidence of what that delay costs is the long lie: lying on the floor for over an hour after a fall is associated with roughly 50% mortality within six months (peer-reviewed cohort; Age UK), driven by dehydration, pressure injury, hypothermia and rhabdomyolysis that accumulate with every hour undiscovered.
From living-alone status to the discovery gap
| Factor | Australian figure | Why it raises discovery-gap risk | Source |
|---|---|---|---|
| Share of 65+ living alone | ~25% | No housemate to witness a collapse | ABS / AIHW |
| Share of 85+ living alone | ~35% | Highest fall risk and most likely to be solo | ABS / AIHW |
| Falls at home (65+) | 53% of hospitalised falls | The incident happens where there is no witness | AIHW, 2019-20 |
| 65+ fall-hospitalisation risk | ~12x that of 25-44 | The most-solo group is the most fall-prone | AIHW, 2023-24 |
| Long-lie 6-month mortality | ~50% within 6 months | Time on the floor, not just the fall, is lethal | Peer-reviewed cohort; Age UK |
| Carers in the population | 3.0M in 2022 | The family network a check-in can mobilise | ABS SDAC, 2022 |
Loneliness lengthens the gap
About 15% of Australians experienced loneliness in 2023 (AIHW / HILDA), a state that concentrates in solo-living older adults and that mechanically reflects a thin network of regular contacts. The fewer people who expect to hear from you on a given day, the longer it takes for anyone to register that something is wrong, which is the exact pathway that turns a survivable event into a fatal one. The carer network has been growing alongside an ageing population: 3.0 million Australians were carers in 2022, about 12% of the population, up from 2.6 million in 2018, with 1.2 million primary carers (ABS SDAC, 2022).
Country comparison: US, Australia, Canada and UK
Australia sits squarely in the middle of the English-speaking pack for older-adult living-alone rates, with all four countries clustering in a fairly narrow band of roughly 24 to 30% of 65+ living alone. The oldest-old gradient is steepest in Canada, where 41.8% of those 85+ live alone (StatCan 2021), with Australia close behind at about 35% of the 85+ band. The women-versus-men gap is universal: 35.1% versus 19.0% in Australia, 40.9% versus 27.0% in the UK, and about 43% of US women aged 75+ living alone. Everywhere, the oldest people living alone are predominantly women, and the implication for families is identical in all four markets.
Older adults living alone across four English-speaking countries
| Country | 65+ living alone | Oldest-band figure | Source |
|---|---|---|---|
| Australia | ~25% | ~35% of 85+ | ABS / AIHW |
| United States | ~28% (~13.8M) | ~43% of women 75+ | US Census, 2022 |
| United Kingdom | 30.1% (E&W, 3.3M) | Women 40.9% vs men 27.0% (65+) | ONS Census 2021 / 2024 |
| Canada | — | 41.8% of 85+ | StatCan Census 2021 |
Each country uses its own statistics agency; definitions of living alone and reference years differ slightly, so the comparison is offered for context rather than as a like-for-like methodological match. Canada's overall 65+ share is not shown because a verified single figure was not available.
Why a daily check-in helps
A quarter of older Australians live alone, that rises to a third of the very oldest, and serious falls overwhelmingly happen at home where a person living alone may have no witness. Most older people living alone are independent, capable and well, so this is not about fear. It is about one quiet fact: if something goes wrong, someone should notice that day, not days later. A simple daily check-in turns nobody would know for hours into someone is told today, supporting independence and peace of mind for the whole family.

Frequently Asked Questions
How many Australians aged 65 and over live alone?
About 1 in 4, roughly 25%, of Australians aged 65 and over live alone (ABS / AIHW). It is the single most common living arrangement risk factor behind the discovery gap, because there is no one else in the home to notice if something goes wrong.
What percentage of over-85s in Australia live alone?
Approximately 35% of Australians aged 85 and over live alone (ABS / AIHW). This is the highest share of any age band, because the oldest group is the most likely to have outlived a partner and is heavily female.
Are most older Australians living alone women?
Yes. At the 2016 Census about 31% of older women lived alone versus 18% of older men, and the 2022 ABS Survey of Disability, Ageing and Carers reported 35.1% of women versus 19.0% of men (ABS, 2016 / 2022). Women live longer on average and are more likely to be the surviving partner, so the oldest, most-solo age bands skew strongly female.
Which Australian state has the most seniors living alone?
Directionally, states with the oldest age profiles, such as Tasmania and South Australia, tend to have higher shares of older residents living alone, while the Northern Territory and the ACT have younger populations and smaller 65+ bases. New South Wales has the largest absolute number simply because it has the largest senior population. Exact ranked percentages should be drawn from ABS Census lone-person-household tables.
What are the risks of living alone for older Australians?
The biggest risks are loneliness, with about 15% of Australians feeling lonely in 2023 (AIHW / HILDA), and slow discovery after an emergency. Falls cause 77% of injury hospitalisations and 71% of injury deaths in older Australians (AIHW, 2019-20), and roughly half of older people who have a long lie die within six months (peer-reviewed cohort; Age UK). Living alone does not make these events more likely; it makes them more dangerous, because help is summoned later.
Is living alone bad for your health?
Living alone is a risk multiplier, not a guaranteed harm. It is strongly associated with loneliness and social isolation, and it lengthens the time before an emergency is noticed. The practical danger is the discovery gap, not living alone in itself, which is why the same person living alone but with a reliable daily check-in faces a much shorter delay before help arrives.
How long can an older Australian lie undiscovered after a fall?
It depends entirely on whether anyone is expected to notice. With a housemate, a fall is usually witnessed within minutes. Living alone, the same fall may not be found until a scheduled call, a visit or a missed appointment, which can be hours or, in the worst cases, days. The danger is quantified by the long lie: over an hour on the floor is associated with roughly 50% six-month mortality (peer-reviewed cohort; Age UK).
Why do more older women than men live alone in Australia?
Three demographic forces combine: women have a longer life expectancy, women are more often the surviving partner after a spouse dies, and repartnering rates after widowhood are lower for older women. The result is the gap the ABS measures directly: 35.1% of older women living alone versus 19.0% of older men in 2022 (ABS SDAC).
Are older Australians more likely to be hospitalised for a fall?
Yes. Older Australians are about 12 times as likely to be hospitalised for a fall as adults aged 25 to 44 (AIHW, 2023-24), and falls cause 77% of injury hospitalisations and 71% of injury deaths among older Australians (AIHW, 2019-20). The exact annual count of falls should be drawn from AIHW's falls hospitalisation data.
Where do most serious falls among older Australians happen?
At home. 53% of hospitalised falls in people aged 65 and over occurred at home, with a further 21% in residential aged care (AIHW, 2019-20). For someone living alone, the home is exactly the setting where a fall is least likely to be witnessed quickly.
How does loneliness affect how quickly someone is found in an emergency?
Indirectly but powerfully. About 15% of Australians experienced loneliness in 2023 (AIHW / HILDA), and loneliness usually reflects a thin network of regular contacts. The fewer people who expect to hear from you on a given day, the longer it takes for anyone to register that something is wrong, the exact mechanism that turns a survivable event into a fatal one for people living alone.
What is a long lie and why does it matter?
A long lie is being unable to get up for more than an hour after a fall. It matters because it is one of the strongest predictors of a poor outcome: roughly half of older people who have a long lie die within six months (peer-reviewed cohort; Age UK). The harm comes not only from the original injury but from dehydration, pressure injury, hypothermia and rhabdomyolysis that build up over time on the floor.
How many carers are there in Australia?
3.0 million Australians were carers in 2022, about 12% of the population, up from 2.6 million in 2018, and 1.2 million were primary carers (ABS SDAC, 2022). This is the informal family network that already does much of the day-to-day checking on older relatives who live alone.
Is a daily check-in or a personal alarm better for someone living alone in Australia?
They solve different parts of the problem. A personal alarm only helps if the person is wearing it and can press it, which a slow collapse, stroke or faint may make impossible. A daily check-in works the other way: if the person does not confirm they are OK, family is alerted regardless of whether any button was pressed. For non-fall medical events and for people who forget or remove a pendant, the check-in closes a gap the alarm cannot.
What number do you call in an emergency in Australia?
Triple zero (000) is the national emergency number in Australia for police, fire and ambulance. For health advice, healthdirect on 1800 022 222 offers a 24-hour nurse line. A daily check-in does not replace 000; it shortens the time before someone realises a 000 call is needed for a person who cannot make it themselves.
Does living alone increase the chance a fall is fatal?
Living alone does not change how likely a fall is, but it can change how fatal a given fall becomes, because discovery is slower. The mechanism is the long lie: over an hour on the floor is associated with roughly 50% six-month mortality (peer-reviewed cohort; Age UK). The modifiable factor is not the fall but the delay before help arrives.
