(CNN)Fans of Denmark must be even happier than usual: Denmark has retaken the title of "world's happiest country," knocking Switzerland into second place.
Denmark and Switzerland were closely followed by Iceland, Norway and Switzerland, according to the World Happiness Report Update 2016, released Wednesday in Rome by the Sustainable Development Solutions Network for the United Nations.
Denmark won the title three of the four times the report has been issued, losing to Switzerland only once.
People in Burundi are the least satisfied with their lives, according to the survey of 156 countries, but residents of Benin (153rd place), Afghanistan (154), Togo (155) and Syria (156) aren't doing much better.
The United States ranked 13th in overall happiness, lagging behind Canada (6), the Netherlands (7), New Zealand (8), Australia (9), Sweden (10), Israel (11) and Austria (12). Germany came in 16th place, while other superpowers -- the United Kingdom (23), Japan (53), Russia (56) and China (83) -- were markedly lower.
Some countries that saw drops suffered economic and political turmoil -- including Greece, Italy and Spain -- while Ukraine's political trouble and violence likely caused a significant drop in happiness there.
10. Sweden 瑞典
Sweden is the world's 10th happiest country, according to the latest World Happiness Report. Already offering plenty to entertain the curious visitor, it now hosts fans of the Millennium trilogy by Swedish author Stieg Larsson. A tour gathers at Bellmansgatan 1, the supposed address of the fictional hero Mikael Blomkvist. No matter what your agenda, take a fika, a coffee break, with your new Swedish friends.
No one visiting ninth-place Australia should miss the Great Barrier Reef, the world's largest collection of coral reefs. But it's worth the effort to get to Whitehaven Beach, with waters so stunning that Sports Illustrated shot part of its 2013 swimsuit issue there.
New Zealand's incredible outdoors, its coffee culture and its delicious food are reason enough to visit. Wellington, the capital city, is also an excellent place to spot wildlife.
When we think of the seventh-place Netherlands, stunning tulips come to mind. Keukenhof Gardens near Lisse opens March 24 for the spring season. Get there before it closes on May 16.
6. Canada 加拿大
Canada came in sixth place, but we’re pretty sure it would have ranked higher if Canadians had been surveyed after these adorable giant panda cubs were born. Prime Minister Justin Trudeau, who knew a good photo op when he saw one, helped unveil their names (Jia Panpan and Jia Yueyue) in March.
5. Finland 芬兰
Fifth-place Finland not only hosts Santa Claus every day of the year (for real). It also has glass igloos at Kakslauttanen, where (in season) you can enjoy the stunning Northern Lights.
Norway is the fourth-happiest country in the world. It could be the sense of community and the hardiness of its people; some choose to surf among the ice in March near Flakstad in Lofoten archipelago. Or it could be the Michelin-starred dining options, including Maaemo (three stars), Restaurant Kontrast (one star) and Renaa: Atriet (one star).
Third-place Iceland's Blue Lagoon, in a lava field, is the country's most famous geothermal spa. You can also mix with the locals at their hot springs or thermal-heated swimming pools all over the country.
Switzerland can't be that sad about slipping into second place this year. Just look at that powder residents and visitors alike can enjoy in Davos, home of one of Switzerland's biggest ski resorts.
After dipping to third place last year,Denmark is once again the happiest country in the world, according to the latest World Happiness Report. January temperatures hovered between zero and minus 4 degrees Celsius at the beach near Fakse Ladeplads, south of Copenhagen. That's enough to encourage the Danish tradition of "hygge," a sense of intimacy, community and contentment that makes for a happy country. "
