If you want to live in the world’s happiest country, you might want to shift to Norway, as it has been termed as the world’s happiest country according to a report released on Monday. The report is prepared every year by the Sustainable Development Solutions Network (SDSN), which is a global initiative which was launched by the United Nations in 2012.

Last year, the title holder country was Denmark, but it appears that Norway did better in terms of making its citizens happy. According to the report, Nordic nations are the most content and other countries should follow suit in terms of building social trust and equality in order to improve the wellbeing of their citizens.

The report also released the names of countries which ranked the lowest in this index. The countries in sub-Saharan Africa, along with Syria and Yemen are the least happy countries of the world out of the 155 countries analyzed.

“Happy countries are the ones that have a healthy balance of prosperity, as conventionally measured, and social capital, meaning a high degree of trust in a society, low inequality, and confidence in government,” Jeffrey Sachs, the director of the SDSN and a special advisor to the United Nations Secretary-General, said in an interview.

According to Sachs, the aim of the report is to provide another tool for governments, business and civil society to help countries find a better way to wellbeing.

According to the SDSN report, the top ranking countries are; Denmark, Iceland, Switzerland, Finland, Netherlands, Canada, New Zealand, Australia, and Sweden. On the other end of the spectrum are the following countries; South Sudan, Liberia, Guinea, Togo, Rwanda, Tanzania, Burundi, and the Central African Republic.

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.
