The World Happiness Report, produced by the U.N Sustainable Development Solutions Network, ranks 156 countries by how happy their citizens see themselves to be.
Finland topped the ranking of the world's happiest countries for the second year in a row, with the Nordic countries taking the leading spots, an annual survey issued on Wednesday showed. The remaining top ten nations were The Netherlands, Switzerland, Sweden, New Zealand, Canada and Austria.
People in war-torn South Sudan are the most unhappy with their lives, followed by Central African Republic (155), Afghanistan (154), Tanzania (153) and Rwanda (152). In the case of this study, they include country's GDP, social support, health life expectancy, freedom to make life choices, generosity, perceptions of corruptions and dystopia-a dictatorial government.
In general, happiness levels have decreased worldwide, however. The United Kingdom is 15th, up four spots from 19th in 2018. The last spot for the least happy nation, 156, went to South Sudan.
The United States came in the 19th place, dropping one spot since previous year and a total of five spots since 2017.
The report said the large gaps in happiness between countries will continue to create pressure to migrate.
This marks a substantial decline for the country, with the report finding that there has been a steep drop in overall life satisfaction and happiness over the last decade.
The UN noted that the Philippines was among the top 20 gainers in the index since 2005 alongside Pakistan, 10 countries in Central and Eastern Europe, five Sub-Saharan Africa counties, three Latin American countries.
"As for emotions, there has been a widespread recent upward trend in negative affect, comprising worry, sadness and anger, especially marked in Asia and Africa, and more recently elsewhere".
But the Danes have stymied the haemorrhaging and are back up to second in UN's latest 2019 World Happiness report (here in English).
