March 20 marks the International Day of Happiness, a reminder that wellbeing is not a “soft” topic but a core pillar of sustainable development. For cities, governments and businesses alike, the question is no longer just how to grow, but how to improve everyday life.
We have already covered global happiness reports in previous issues, and the newly released World Happiness Report 2026 adds another layer to that conversation, with a mix of familiar leaders and less obvious trends.
At the top, little has changed. Finland remains the world’s happiest country, followed by Iceland and Denmark. One of the more interesting shifts comes from outside Europe. Costa Rica has climbed to fourth place, the highest position ever reached by a Latin American country.
More broadly, the picture is not as pessimistic as it may seem. Over the past decade, nearly twice as many countries have seen improvements in life satisfaction as those that have experienced declines. Much of that progress is coming from Central and Eastern Europe, where wellbeing levels are gradually catching up with Western Europe.
At the same time, many developed economies are moving in the opposite direction. In North America and parts of Western Europe, people report lower levels of happiness than they did 15 years ago. The most concerning signal comes from younger generations. In countries such as the United States, Canada and Australia, youth wellbeing now ranks unexpectedly low by global standards.
There is no single explanation, but the report points to several overlapping factors. One of them is the changing nature of social life in the digital era. Online communication can support connection and learning, but heavy and passive use of social media is increasingly associated with lower life satisfaction, especially among teenagers.
At the same time, the foundations of wellbeing remain clear. Trust, a sense of belonging and strong social ties continue to matter more than many economic indicators. The data suggests that feeling connected, whether at school, at work or in the community, has a stronger impact on happiness than many commonly discussed factors.
The overall message is straightforward. Happiness is becoming more uneven across countries and generations. For policymakers, including those shaping cities, this makes the challenge not only more complex, but also more urgent.
