Switzerland the world's happiest place, Afghanistan and Syria among the least happy

China is getting happier, Hong Kong is getting sadder, and Switzerland is the happiest place of all.
Those were among the findings of a new global ranking of happiness unveiled in New York. Switzerland, happiest country in the world, was closely followed by Iceland, Denmark, Norway and Canada, according to the 2015 World Happiness Report.
It is the third such report seeking to quantify happiness as a means of influencing government policy. The United Nations published the first study in 2012.
Finland, the Netherlands, Sweden, New Zealand and Australia round out the top 10, making small or medium-sized countries in Western Europe seven of the top 10 happiest countries.
China was ranked 84th, a solid improvement from its 93rd-place position in the last survey in 2013. Hong Kong, however, slid down the rankings to 72nd place, compared to 64th in the last poll.
Academics identified the variables as real GDP per capita, healthy life expectancy, having someone to count on, perceived freedom to make life choices, freedom from corruption and generosity.
