Australia is the happiest nation in the world according to the Organisation for Economic Co-Operation and Development. This is the third year in a row that the nation has made the top of the list.
It beat out other happy countries like Sweden, Norway, Canada and Switzerland. The list of happiest countries is restricted to nations with developed economies.
Australia received first place mainly because of its stronger economy.
They also have higher income levels, better health, safety and housing.
"Australia performs exceptionally well in measures of wellbeing, as shown by the fact that it ranks among the top countries in a large number of topic in the Better Life Index," the OECD said.
They found that 73 percent of Australia's 23 million residents ages 15 to 64 have a paid job. Their life expectancy is also a lot higher than other countries, at 82 years.
"Access to clean water is fundamental to human well-being and 91 percent of Australians say they are satisfied with water quality, higher than the OECD average of 84 percent," OECD said.
Residents of the country work about 1,693 hours a year, two weeks less than the OECD average. Americans work a little over this amount at 1,787 hours a year. Germans work only 1,413 hours a year.
Australians might also be happy because they eat well. Twenty-five percent of Australians are obese, higher than the OECD average of 17.8 percent. But 85 percent of Australians reported that they had "good health" despite being obese.
"Obesity rates are high in Australia and they have been increasing faster than in most other OECD countries over the past 20 years," the report said.
