Good cheer may feel in short supply as the world reels under a global pandemic, but experts at the United Nations on Friday declared Finland to be the world’s happiest nation for the third year running. Researchers for the World Happiness Report asked people in 156 countries to evaluate their own levels of happiness, and took into account measures such as GDP, social support, personal freedom and levels of corruption to give each nation a happiness score. The happiest countries are those “where people feel a sense of belonging, where they trust and enjoy each other and their shared institutions,” John Helliwell, one of the report’s authors, said in a statement.
