Flying Solo After 40
I’ve been reading lately. Research on Australian women over 40 living alone, which is summarised here. One thing it confirms straight away: being single and being lonely are not the same thing. We tend to treat them like they are.
The Shift Is Real
The shift is real. Australia is in the middle of a quiet one. More women over 40 are living alone than ever before. Some choose it. Some arrive there after a split. Some just find themselves there. By 2046, between 3.4 and 4 million Australians are expected to live alone. That is a rise of 30 to 50 per cent on 2021 numbers. Women make up a growing share of this group, especially from age 50 on. By age 80 and over, 4 in 10 Australian women live alone.
The gap between men and women grows with age, for a few fairly ordinary reasons. Women live longer. Men tend to date younger women. And after a split, men find a new partner far more often than women do. Add those together, and by the late 70s, 72 per cent of men are still married, compared with only 49 per cent of women.
The median age at first marriage for Australian women is now 30. Back in 1974, the low point, it was 20.9. Divorce rates for women in their 40s and 50s have climbed too. Women are more often the ones who end it. Add it all up, and you get a large group of women living outside the old rules.
Being Single Is Different
One thing matters most. Being single is not the same as being lonely.
Many single women over 40 have full lives. Close friends. A real sense of belonging. Many partnered women feel deeply alone. The research says this again and again.
That said, single women over 40 do face a higher risk of loneliness. What that means for health is worth exploring.
A 2025 study looked at 18 years of data on more than 57,000 Australian women. Women do not simply split into two camps, lonely and not lonely. Their loneliness moves over time. Some stay low. Some climb slowly along a continuum. Some get stuck feeling lonely for years.
What pushes a woman toward that harder path? A break up. Kids leaving home. Caring for ageing parents. Retiring. Menopause. These all tend to land in the same window, between 40 and 60. Women who were already feeling low, anxious or stressed, who smoked, or who had less support around them, were more likely to end up on the harder path.
“The older you get, the harder it is to meet people.” That line ran in the Australian Women’s Weekly this February. It named what so many women already feel.
The Health Stakes
The health research matters here. In April 2025, researchers from the University of Sydney published a world first finding. Chronic loneliness, they found, is not just linked to earlier death in Australian women 45 and over. It plays a causal role.
Women who felt lonely across six surveys over 15 years were three times more likely to die early than women who never did, even after health was factored in. And the longer loneliness lasted, the more the risk grew. This is exactly why catching it early, and having somewhere to turn, makes such a difference.
The researchers were direct about what should happen next. Loneliness, they said, deserves the same attention from doctors as blood pressure or diabetes risk. Right now in Australia, that is not standard practice.
Chronic loneliness is also linked to heart disease, diabetes, depression, anxiety and dementia. A second study in 2025 tracked women over 18 years. Those who stayed lonely for years felt worse, in both body and mind, unsurprisingly.
One more finding is worth sharing. A 2026 study looked at older adults in new relationships. On tense days, they had more headaches, nausea and body stress than younger daters did. Opening back up to closeness in midlife is not a small thing. Whatever remains unresolved can be triggered and shows up in the body.
Not One Story
Women over 40 relate to being single in very different ways, and the range is wide. Understanding that range matters for how they are supported.
Consciously single and thriving.
Many women make a real choice to stay single. They are genuinely thriving in it. A 2025 Australian study found being single was often a place of growth, freedom and self discovery. That study looked at younger women, so I hold it as a pattern worth watching rather than direct proof for women over 40, but it echoes what I hear constantly in my own work. In 2025, 66 per cent of Australian women said they were being more honest with themselves. They said they had stopped settling in relationships. This is not giving up. It is getting clear.
After a split, a silver lining.
Many women arrive at being single after 40 through a split, not by choice. Here the research holds something surprising. A 2025 study followed over 1,400 separated women in midlife and compared them with 2,500 women who stayed partnered. Life satisfaction dropped sharply around the time of the split. Then, over the following years, it climbed back up, and climbed further than it did for the women who stayed partnered. What made the difference was not finding a new partner. It was support from others, a sense of control over their own life, and having enough money behind them.
Actively seeking a partner.
Plenty of women over 40 want a partner and are out there looking. Among Australians over 50 who are not currently in a relationship, one in five are dating, and three in four of those not yet dating hope to be. On dating apps built for older users, 75 per cent of women say they want something serious. These women face real hurdles. The pool of single men shrinks with age. In the older years, there are at least two single women for every single man. A 2024 survey found 70 per cent of Australians have never used a dating app. Most partner seeking at this age still happens the old way, through friends and social circles. Those circles shrink too, as women get older.
The Real Barriers
Wanting a partner is not always enough. Even women who want one can find that dating costs more than it gives back, and not because of anything wrong with them.
Old hurt that shapes how the body reacts to closeness now
Fear of judgment, most of all where partnership is expected by well meaning friends and family
A double standard on age that hits women harder than men
Pressure around body image, made worse by apps built on looks
The real cost of opening up again, after years of standing on her own
Dating app fatigue, and a culture built for speed, not depth
None of this is a flaw in her. These are learned responses to real experience. They call for patient, informed support. Not a cheerful push to just get back out there.
Four Things Worth Noting
Four things stood out.
Loneliness, not being single, is the health risk. The early death research points to chronic loneliness. Not to any one way of living. The goal should be real connection, whatever the relationship status.
Quality beats presence. A new partner did not raise wellbeing for Australian women after divorce. That challenges a belief many of us hold without question. A poor relationship does not protect anyone’s health. Real connection, in any form, does.
Structural barriers need real attention. The shrinking pool of men. The ageism built into dating culture. The money pressure that follows a midlife split. No woman can solve these alone. They are bigger than any one person, and they need a bigger response.
Loneliness needs to be taken seriously in healthcare. The UK already does something close to this. GPs there can refer a patient to a social prescribing worker, someone whose whole job is helping people rebuild connection, not just treating symptoms. Australia has nothing built into routine care like it yet, and for something linked this closely to early death, that is a real gap.
Where I Sit
This is my work. I work with women in exactly this space. Some are solo by choice. Some are freshly separated. Some feel quietly lonely. Some are out there looking
for connection. What the research shows is what I see in the room every week. The goal was never to find someone to complete you. It is to know yourself well enough that whatever you choose next, alone or partnered, comes from a place of wholeness. Not worth you have to earn.
If any of this landed for you, I would love to hear from you.
