Something unusual is happening to the happiness curve

For decades, researchers often described happiness across adulthood as a U-shaped curve. People tended to report relatively high well-being when young, lower well-being in middle age, and then an improvement later in life. Being young came with instability, but also possibility. You had time, fewer obligations, and a broad cultural assumption that things would gradually improve. Recent research suggests that this familiar pattern may be changing.

A 2025 study by David Blanchflower, Alex Bryson and Xiaowei Xu, using recent data from 44 countries, found that the traditional age pattern of ill-being had weakened dramatically. Instead of psychological distress peaking around middle age, younger people increasingly reported worse mental health than older age groups. The authors argue that deteriorating mental health among the young, rather than an extraordinary happiness boom among retirees, is driving the change. European evidence points in the same direction. A Norwegian population study tracking mental health across three decades found a sharp increase in distress among adolescents and young adults, especially between 2006–2008 and 2017–2019, while depressive symptoms declined among adults aged 60 and over.

The World Happiness Report 2026 adds an important geographical nuance. Youth wellbeing has not collapsed everywhere. Across most regions, people under 25 rate their lives more positively than in 2006–2010. The two major exceptions are English-speaking North America, Australia and New Zealand, and Western Europe, where youth wellbeing has declined both in absolute terms and relative to older adults. So this is not simply a Gen Z story. It may be a story about what it means to become an adult in wealthy Western societies today.

Young Europeans are not simply unhappy

An important contradiction lies here, and we should keep it because it makes the story more interesting. Eurostat’s latest data shows that in 2024, Europeans aged 16 to 29 still reported higher overall life satisfaction than older age groups at the EU level. Young people also report very high satisfaction with their personal relationships, and around 90% describe their own health as good or very good. So the evidence does not justify headlines claiming that Gen Z is miserable.

At the same time, Eurofound measures something slightly different. Between 2020 and 2023, young Europeans aged 16 to 29 were consistently more likely than people aged 30+ to report feeling tense, lonely or depressed most or all of the time. In 2023, 19.3% of young adults reported frequent loneliness compared with 11.1% among older adults, while 15.4% reported feeling depressed compared with 9.8% among the 30+ group. Both things can be true at once. You can like your friends, enjoy your weekend, feel physically healthy, and still worry about where your life is going. You can have a decent Tuesday and an uncertain future. That distinction may be the key to understanding Gen Z wellbeing.

The problem may be progress

When we talk about young people and mental health, the conversation often shifts almost immediately to smartphones. Evidence shows that digital life matters. In the EU, 97% of 16- to 29-year-olds use the internet every day, and 88% use social networks. The World Happiness Report 2026 finds that the relationship between internet use and wellbeing is more negative for Gen Z than for older generations, although the effects depend heavily on how technology is used, by whom and in what context. It also concludes that social relationships and belonging are associated with even larger differences in wellbeing.

So “phones made young people unhappy” is an attractive explanation because it fits comfortably into one sentence. Unfortunately, reality appears to require more than one sentence. Consider what has changed around young adulthood. AI is reshaping entry-level work. Housing costs make independence harder. Homeownership is happening later. Relationships form differently. Marriage and children are increasingly treated as choices rather than automatic milestones. The pandemic interrupted education and social development. The cost of living increased. And many of the institutions that traditionally provided a sense of progression now feel less predictable.

This matters because being young has always involved having less. Less salary, less property, less professional status, less certainty. What compensated for that was often an expectation of more later. You might have been broke at 24, but the cultural script suggested you would progress. Your salary would increase. You would eventually find somewhere to live. Your career would develop. Maybe you would meet someone, buy something, build something. The current generation may be facing a different psychological equation. The problem is not necessarily having less today. It is being less certain that more is coming tomorrow.

Money matters because money buys possibility

Research also shows that wellbeing cannot be separated neatly from economics. An analysis of European Social Survey data found that the relationship between age and happiness changes significantly according to income. People in the lowest income groups showed a much steeper decline in happiness across adulthood, while happiness varied far less by age among people with high incomes. This fits with what we have been seeing across many of the subjects covered on 20something.

Housing is not simply about square meters. It is about being able to leave your parents, live with a partner, choose a city, have privacy and imagine starting a family. Work is not simply about salary. It is about developing competence, building an identity and believing that effort will lead somewhere. Financial security isn’t just about having money in an account. It creates options. When those options feel narrower, wellbeing can become a question of perceived mobility: can I move forward?

That may matter more than whether someone’s current lifestyle looks objectively comfortable. A 25-year-old can have an iPhone, Spotify, cheap flights, brunch, and access to more entertainment than a king had a century ago and still feel anxious about whether they will ever afford a home. Material abundance and confidence in the future are not the same thing.

We may also have underestimated the connection

Another part of the story deserves more attention. A fascinating 2026 study followed 17,390 young people in Germany and the United Kingdom between ages 16 and 29. Young adults who remained consistently single showed, on average, larger declines in life satisfaction and increases in loneliness as they moved through their twenties compared with those who eventually entered a relationship. The differences became more pronounced towards the late twenties. Entering a first romantic relationship was associated with greater life satisfaction and reduced loneliness, although it did not automatically reduce depressive symptoms.

This does not mean everybody needs a partner to be happy. Nor does it mean singlehood causes poor mental health. The relationship runs in both directions, and the researchers explicitly show that people with lower wellbeing were also more likely to remain single longer. But it points towards something bigger: human connection still matters enormously.

The World Happiness Report 2026 finds that among younger Europeans, particularly in Western Europe, declines in wellbeing have been accompanied by deteriorating interpersonal trust, institutional trust, perceived social activity, and frequency of social meetings. These declines are especially pronounced among younger women. This makes the current revival of offline communities, run clubs, hobby groups, shared living, and real-world social spaces more interesting than a lifestyle trend. Maybe young people are not suddenly becoming nostalgic for analog life. Maybe they are looking for forms of connection that digital abundance hasn’t replaced.

This is not one crisis with one villain

Whenever a generation changes, we’re tempted to find one explanation. It was COVID. It is TikTok. It is housing. It is capitalism. It is dating apps. It is helicopter parenting. It is AI. Pick your villain.

Research does not give us permission to do that. Overlapping forces seem to drive declines in some dimensions of young adult well-being. Economic conditions matter. Income matters. Housing matters. Relationships matter. Digital behavior may matter. Social trust matters. Work matters. The pandemic mattered. These factors interact differently depending on gender, country, income, and personal circumstances.

This also explains why two apparently contradictory statistics can coexist. Eurostat can find relatively high life satisfaction among young Europeans while Eurofound finds elevated loneliness and psychological distress. One measures an overall judgment about life. The other captures difficult emotional experiences. Young people can still enjoy their lives while worrying about where they’re headed. And that, to me, is where the real story sits.

Maybe Gen Z needs more than resilience

For years, organizations have responded to declining youth wellbeing with the language of resilience: wellbeing programs, mindfulness apps, mental health days, and stress-management workshops. Some of those initiatives are useful. But treating every structural problem as an individual coping challenge is dangerous.

If a young employee cannot afford housing near the office, telling them to become more resilient will not lower the rent. If junior jobs stop providing real opportunities to learn, meditation will not create a career path. If people feel socially disconnected, another Teams meeting about wellbeing is unlikely to rebuild community. Perhaps leaders need to ask a different question. Not only: How do we help young people cope? But: What are they being asked to cope with?

That distinction matters because Gen Z may not simply be less resilient than previous generations. They may be entering adulthood under a combination of economic, technological, and social conditions that make progress harder to see. And people need progress. Not necessarily a promotion every six months. Not a house at 25. Not marriage, children and a golden retriever before 30. But some believable sense that effort can lead somewhere.
