America’s top doctor says governments’ failure to better regulate social media is ‘insane’.

Young people are becoming less happy than older generations as they suffer “the equivalent of a midlife crisis”, global research has revealed as America’s top doctor warned that “young people are really struggling”.

Dr Vivek Murthy, the US surgeon general, said allowing children to use social media was like giving them medicine that is not proven to be safe. He said the failure of governments to better regulate social media in recent years was “insane”.

Murthy spoke to the Guardian as new data revealed that young people across North America were now less happy than their elders, with the same “historic” shift expected to follow in western Europe.

Declining wellbeing among under-30s has driven the US out of the top 20 list of happiest nations, the 2024 World Happiness Report revealed.

After 12 years in which people aged 15 to 24 were measured as being happier than older generations in the US, the trend appears to have flipped in 2017. The gap has also narrowed in western Europe and the same change could happen in the coming year or two, it is thought.

Murthy described the report findings as a “red flag that young people are really struggling in the US and now increasingly around the world”. He said he was still waiting to see data that proved social media platforms were safe for children and adolescents, and called for international action to improve real-life social connections for young people.

The World Happiness Report, an annual barometer of wellbeing in 140 nations coordinated by Oxford University’s Wellbeing Research Centre, Gallup and the UN Sustainable Development Solutions Network, showed “disconcerting drops [in youth happiness] especially in North America and western Europe,” said Prof Jan-Emmanuel De Neve, director of the Wellbeing Research Centre and editor of the study.

British people under 30 ranked 32nd in the rankings, behind nations such as Moldova, Kosovo and even El Salvador, which has one of the world’s highest murder rates.

The World Happiness Report tracks subjective wellbeing using respondents’ own assessments of their lives and their positive and negative emotions. Once again Finland, Denmark and Iceland were the top three happiest countries.

Costa Rica and Kuwait were new entrants to the top 20. Germany dropped from 16th to 24th. Afghanistan and Lebanon stayed as the two least happy nations. Countries that enjoyed increasing happiness included many African nations, Cambodia, Russia and China. Serbia recorded the biggest increase in happiness.
