我们的研究考察了43个国家青少年的社交媒体行为——来自弱势背景的群体面临更大的危害。

As social media becomes a central part of young people’s lives, concerns are growing about its impact on their mental health. Yet public debates and measures tend to treat adolescents as one homogeneous group. We frequently ignore the fact that social media use does not affect all young people in the same way – nor does it have the same impacts on their wellbeing.

In a recent chapter of the World Happiness Report 2026, published by the UN Sustainable Development Solutions Network in partnership with the University of Oxford, we have examined how problematic social media use relates to the wellbeing of adolescents from different socioeconomic backgrounds.

We looked at 43 countries spanning six broad regions – Anglo-Celtic, Caucasus-Black Sea, Central-Eastern Europe, Mediterranean, Nordic, and Western Europe – covering mainly European countries and their immediate neighbouring areas.

Using data from over 330,000 young people, we found a clear and consistent pattern: higher levels of problematic social media use – that is, compulsive or uncontrolled engagement with social media – are associated with poorer wellbeing.

Teenagers who report more problematic use tend to experience more psychological complaints, such as feeling low, nervous, irritable, or having difficulty sleeping. They also have lower life satisfaction, a measure of how positively they evaluate their lives as a whole.

This pattern appears across all countries in our study, but its strength varies from one country to another. It is particularly pronounced in Anglo-Celtic countries such as the UK and Ireland, while it is comparatively weaker in the Caucasus-Black Sea region.

Socioeconomic background matters

The story does not end with geography. Globally, teenagers from less advantaged backgrounds tend to be more vulnerable to the negative consequences of problematic social media use than their more advantaged peers.

This means socioeconomic status – the material and social resources available to a household, such as income and living conditions – actively shapes the risks and opportunities that young people experience as a result of online environments.

Interestingly, these inequalities are especially visible when we look at life satisfaction. Differences between socioeconomic groups are smaller when it comes to psychological complaints, but much clearer and more consistent for how adolescents evaluate their lives overall.

One likely reason is that life satisfaction is more sensitive to social comparisons. Social media exposes young people to constant benchmarks – what others have, do, and achieve – which can amplify differences in perceived opportunities and resources.

At the same time, these patterns are not identical everywhere. For instance, socioeconomic differences in psychological complaints tend to be modest in most regions including continental European countries such as France, Austria or Belgium, but are more clearly observed in Anglo-Celtic countries such as Scotland and Wales.

In contrast, socioeconomic gaps in life satisfaction appear across most regions, although they tend to be weaker in Mediterranean countries such as Italy, Cyprus and Greece.

A growing problem

We also examined how these patterns have evolved over time. Between 2018 and 2022, the link between problematic social media use and poor adolescent wellbeing became stronger.

This suggests that the risks linked to problematic use may have intensified in recent years, possibly reflecting the growing role of digital technologies in young people’s daily lives, particularly during and after the Covid-19 pandemic.

Importantly, this intensification has affected teenagers across socioeconomic groups in broadly similar ways in most regions. In other words, while inequalities remain they have not widened over this period.

No one-size-fits-all solution

While public debates about social media and mental health often treat adolescents as a single demographic group, our results show a more complex reality. Problematic social media use is linked to poorer wellbeing across countries, but its effects are shaped by social realities. They vary depending on where young people live and what resources are available to them.

Not all teenagers experience the digital world in the same way, and not all are equally equipped to cope with its pressures. Recognising this is essential for designing policies that are not only effective, but also equitable, ensuring that interventions reach those adolescents who are most vulnerable to digital risks.
