National indices of happiness

The 2020 World Happiness Report, the eighth in the series of reports, was the first to include happiness rankings of cities across the world, in addition to rankings of 156 countries. The city of Helsinki, Finland was reported as the city with the highest subjective well-being ranking, and the country of Finland was reported as the country with the highest subjective well-being ranking. The 2020 report provided insights on happiness based on environmental conditions, social conditions, urban-rural happiness differentials, and sustainable development. It also provided possible explanations for why Nordic countries have consistently ranked in the top ten happiest countries in the World Happiness Report, such as Nordic countries' high-quality government benefits and protections to its citizens, including welfare benefits and well-operated democratic institutions, as well as social connections, bonding, and trust.
