The researchers behind the World Happiness Report, now in its ninth year, used Gallup data asking people in 149 countries to rate their own happiness, also taking into account measures such as GDP, social support, personal freedom and levels of corruption to give each nation a happiness score, which is an average of the past three years.

Covid-19 has done little to alter the ranking of the world’s happiest countries, with Finland at the top for a fourth year running, an annual UN-sponsored report said on Friday.

Once again, the top spots were dominated by European countries — with Denmark coming second, followed by Switzerland, Iceland and the Netherlands.

New Zealand, was again the only non-European nation in the top ten falling one place to ninth, other climbers included Germany, up from 17th to 13th, and France, rising two to 21st.

The UK, meanwhile, fell from 13th to 17th place, while the US fell one spot to 19th.

African nations Lesotho, Botswana, Rwanda and Zimbabwe came at the bottom of the table, but ahead of Afghanistan which was classed as the world’s unhappiest nation this year.

The authors also compared this year’s data to previous years’ averages to gauge the impact of the pandemic, and found “significantly higher frequency of negative emotions” in just over a third of the countries.
