What the World Happiness Report reveals about social media and the world’s happiest country
Heavy social media use contributes to a stark decline in well-being among young people, with the effects particularly worrying in teenage girls in English-speaking countries and Western Europe, according to the World Happiness Report 2026.
The annual report, published by the Wellbeing Research Centre at the University of Oxford, also found that Finland is the happiest land in the world for the ninth year in a row, with other Nordic countries such as Iceland, Denmark, Sweden, and Norway ranking among the top 10 countries.
But it highlighted how life evaluations among under 25-year-olds in the United States, Canada, Australia, and New Zealand have dropped significantly over the past decade, and suggested that long hours spent scrolling through social media is a key factor in that trend.
Costa Rica jumps to 4th place; Nordic countries stay on top
A new entry to the top five on the list is Costa Rica, which climbed to fourth place this year after rising through the ranks from 23rd place in 2023.
The report attributes that to well-being boosts from family bonds and other social connections.
“We think it’s because of the quality of their social lives and the stability that they currently enjoy,” said Jan-Emmanuel De Neve, an Oxford economics professor who directs the Wellbeing Research Centre and co-edits the World Happiness Report.
The report said Finland and the other Northern European countries’ steady ranking on top is related to a combination of wealth, its equal distribution, having a welfare state that protects people from the risks of recessions, and a healthy life expectancy.
As in previous years, nations in or near zones of major conflict remain at the foot of the rankings. Afghanistan is ranked as the unhappiest country again, followed by Sierra Leone and Malawi in Africa.
Country rankings were based on answers given by around 100,000 people in 140 countries and territories who were asked to rate their own lives. The study was done in partnership with the analytics firm Gallup and the UN Sustainable Development Solutions Network.
Teenage girls especially vulnerable
The report said the negative correlation between well-being and extensive social media use is particularly concerning among teenage girls. For example, it said that 15-year-old girls who use social media for five hours or more reported a drop in life satisfaction, compared to others who use it less.
Young people who use social media for less than one hour per day report the highest levels of well-being, researchers said, higher than those who do not use social media at all. But adolescents are spending an estimated average of 2.5 hours a day on social media.
Algorithmic feeds and influencers seen as culprits
Researchers noted that in some parts of the world, such as the Middle East and South America, the links between social media use and well-being are more positive—and youth well-being has not fallen despite heavy social media use.
The report said this is due to many factors that differ between continents, but concluded that heavy social media use in some countries is an important contributing factor to the decline in youth well-being.
