A UN's Sustainable Development Solutions Network (SDSN) report indicates that Denmark is the world's happiest country while Burundi is the least happy, according to a new survey.
The compilation which is the fourth of its kind is an analysis of Gallup World Poll data generated from surveys of 1,000 people in each country every year for three years.
They were asked to evaluate their lives on a ladder scale of zero to 10.
The report also found that countries where there was less inequality were happier overall.
It found out that people are happier living in societies where there is less inequality of happiness. Likewise, the bigger the gap - or inequality - in a country's happiness, the more widespread unhappiness is as a whole.
Six key categories were defined:
gross domestic product (a nation's output of goods and services)
charitable giving and perceived corruption
Other factors were social support and level of corruption; with social support defined as being able to count on someone in difficult times.
"Human wellbeing should be nurtured through a holistic approach that combines economic, social and environmental objectives," Columbia University Earth Institute Director Jeffrey Sachs said in a SDSN press release.
The statement urged countries to rather than taking a narrow approach focused solely on economic growth, to promote societies that are prosperous, just, and environmentally sustainable.
The Nordic countries, Switzerland, Iceland, Norway and Finland, which like Denmark have strong social security systems, respectively ranked as the rest of the top five.
The US was the world's 13th happiest country, the UK was 23rd, China was 83rd, India was 118th and Ghana, 124.
Burundi with all its worse human right abuses and high level of political unrest, ranked as the bottom placed of the 156 countries on the list.
Syria scored higher than the African state, even though civil war has killed over 250,000 Syrians over the past five years.
The survey revealed that Syrians had better healthy-life expectancy and were also seen as being more generous than Burundians and people in the three other nations - Togo, Afghanistan and Benin - making up the five least happy countries.
Northern America, Latin America and the Caribbean and Europe were the happiest regions overall,
Whilst South Asia and sub-Saharan Africa came in as the only regions where the average rating for wellbeing was less than five out of 10.
