Most of us quietly assume that happiness is something you spend as you age, that the best years are early and the slope runs downhill from there. It is one of the more widely held fears about growing older, and for a long time the data pointed the other way.
I am a writer with an interest in this research, not a psychologist, so take this as a careful reading rather than a promise about anyone’s life. But the broad pattern is more hopeful than the fear, and it is worth understanding, including the part that has recently started to change.
The curve almost nobody expects to be on
For decades, surveys of life satisfaction turned up the same odd shape when plotted against age: a U. People tended to start fairly high in youth, decline through their thirties and forties to a low point somewhere around the late forties, and then climb again through their fifties, sixties and into their seventies.
The economists David Blanchflower and Andrew Oswald documented this across a large number of countries. In one analysis of 145 countries, Blanchflower found the midlife dip almost everywhere, in rich and poor economies alike, with the low point falling near age fifty. The striking part is the recovery: the satisfaction many people report in their late sixties is often higher than what they felt in their thirties.
This is a claim about averages, not about any one person, and it has its critics. The economist Angus Deaton has argued the U is not as universal as the headline suggests, and that it depends on circumstances. It is also worth remembering what these surveys actually measure, which is usually a considered judgement about life as a whole. I have written before about what that kind of question does and does not capture.
Why later life can be the good part
If happiness really does tend to rise in later life, the obvious question is why, given that ageing also brings loss, illness and shrinking horizons.
The most persuasive answer I have come across is from the Stanford psychologist Laura Carstensen, whose socioemotional selectivity theory starts from a simple observation. When people sense that time is limited, they change what they reach for. Younger people, with long horizons, chase novelty, information and future possibility. Older people, sensing the runway shorten, spend their attention on what already matters to them: close relationships, familiar pleasures, the present rather than the hypothetical.
Carstensen’s group also described what they call the positivity effect, a tendency for older adults to weight and remember positive information more than negative. The result is a genuine puzzle that researchers named the paradox of ageing: emotional wellbeing that improves even as the body and the social world contract.
There is a related thread in the same research: older adults, on average, tend to report steadier moods and to recover from bad ones more quickly than younger adults do. Emotional life does not so much cool as settle.
Put plainly, part of what makes later life happier may be that people get better at spending their time and attention on what they actually value, and less inclined to waste it.
The catch: the curve is changing
Here is where I have to add the honest complication, because the picture is not static.
More recent work by Blanchflower and Alex Bryson finds that the classic U-shape has been coming apart, and not because older people got sadder. In a 2025 paper in PLOS One, they report that since around 2013 the wellbeing of young adults has fallen sharply in many countries, especially among young women. The youthful high that formed the left side of the U has eroded.
So in a lot of recent data the shape is no longer a U at all. Instead, wellbeing rises fairly steadily with age, starting low in young adulthood and climbing from there. The midlife crisis, as a distinct dip, has faded, mostly because the young are now starting from a harder place.
Researchers have noted that the decline set in around the early 2010s, roughly alongside the spread of smartphones and social media, though the causes are genuinely debated and unlikely to come down to any single thing.
This is unsettling news about youth, but it does not undo the part relevant here. The finding that later life tends to be a relatively good stretch for wellbeing has held up. What changed is the beginning of the line, not the end.
What this does and does not mean
For anyone bracing themselves against getting older, I think the fair reading is cautiously encouraging. On average, and across a lot of countries and years, later life has not been the emotional decline people dread. It has more often been the opposite.
But average is the important word, and this is not advice. A curve drawn from millions of people cannot tell you how your own later years will feel. Health, money, relationships and plain luck shape individual lives far more than any population trend, and none of the research says otherwise. Grief and hardship do not politely wait until the graph turns up.
What the work does offer is a correction to a specific and common piece of pessimism. The assumption that the feeling of a life gets worse as it lengthens is not well supported, and for a great many people the reverse has been true.
The interesting possibility buried in Carstensen’s work is that some of this is learnable rather than merely waited for. Getting older seems to teach people to spend their attention on what they care about. That is not a bad lesson to borrow early.
