Norway displaces its neighbour Denmark as the world’s happiest country in a new report that assesses life expectancy, freedom, social support and corruption, among other measures.

OSLO, NORWAY (MARCH 20, 2017) (REUTERS) – Norway displaced Denmark as the world’s happiest country in a new report released on Monday (March 20) that called on nations to build social trust and equality to improve the well-being of their citizens.

The Nordic nations are the most content, according to the World Happiness Report 2017 produced by the Sustainable Development Solutions Network (SDSN), a global initiative launched by the United Nations in 2012.

Denmark, Iceland, Switzerland, Finland, Netherlands, Canada, New Zealand, Australia and Sweden rounded out the top 10 countries.

Countries in sub-Saharan Africa, along with Syria and Yemen, are the least happy of the 155 countries ranked in the fifth annual report released at the United Nations.

South Sudan, Liberia, Guinea, Togo, Rwanda, Tanzania, Burundi and the Central African Republic were at the bottom.

Germany was ranked 16, followed by the United Kingdom (19) and France (31). The United States dropped one spot to 14.

The rankings are based on six factors — per capita gross domestic product, healthy life expectancy, freedom, generosity, social support and absence of corruption in government or business.
