The World's Happiest Countries, 2025

March 20 is the United Nations (U.N.) International Day of Happiness. Each year, the U.N., the University of Oxford, and Gallup release the World Happiness Report, a ranking of more than 140 countries according to the perceived happiness of their citizens.

The ranking is based on one question: "Please imagine a ladder with steps numbered from 0 at the bottom to 10 at the top. The top of the ladder represents the best possible life for you and the bottom of the ladder represents the worst possible life for you. On which step of the ladder would you say you personally feel you stand at this time?" Each country's ranking is then based on a three-year average of participant answers to this question. Following are results from last year's ranking.
