Happiness is a state of mind — but it can also be a place. Specifically Norway, which has been crowned as the world's happiest country in the World Happiness Report 2017.
It's closely followed by two other Nordic nations, Denmark and Iceland, and then Switzerland in the annual report, which was published by the Sustainable Development Solutions Network and released at the United Nations on Monday, March 20, 2017.
The rankings are calculated using data from the Gallup World Poll. The full report can be found at worldhappiness.report.
Norway takes the title of the world's happiest country this year. It climbed three spots from fourth in 2016 -- though, as the report notes, the top four's scores are close to one another's. Those countries "rank highly on all the main factors found to support happiness: caring, freedom, generosity, honesty, health, income and good governance," the report says.

Denmark was dethroned from the top spot it claimed in 2016, but No. 2 is still plenty happy. "What works in the Nordic countries is a sense of community and understanding in the common good," explained Meik Wiking, chief executive officer of the Happiness Research Institute in Copenhagen, to The Associated Press. Wiking was not part of the World Happiness Report.
