For the first time in the World Happiness Report’s dozen-year history, the U.S. did not rank in the top 20 of the world’s happiest countries. 

Out of the more than 140 nations surveyed, the U.S. landed in 23rd place, compared to 15th place in 2023. While the U.S. is still in the top 10 happiest countries for those 60 years old and above, its overall ranking fell due to a significant decline in the reported well-being of Americans under 30. 

Finland ranked at the top of the list for the seventh year in a row. Lithuania is the happiest country in the world if you only look at those under the age of 30, while Denmark is the happiest country for people who are 60 and older.

This was the first year the report, released March 20 to mark the UN’s International Day of Happiness, analyzed rates of happiness by age group. “We found some pretty striking results,” said John F. Helliwell, professor at the Vancouver School of Economics and founding editor of the World Happiness Report. “There is a great variety among countries in the relative happiness of the younger, older, and in-between populations. Hence the global happiness rankings are quite different for the young and the old, to an extent that has changed a lot over the last dozen years.”
