Life may be difficult at times. Sometimes the world seems too much to handle, whether it's stress at job, home, school, or somewhere else entirely. And when you really need to get away from it all, there are certain places that have been shown to be happier and carefree than others. 

In order to determine which countries are the happiest on Earth, Casino.com conducted an analysis in June that examined the list of countries that, according to The United Nations Development Program, have a Human Development Index Score of over 0.8. The analysis also examined each country's average salaries, unemployment rates, crime rates, sunshine hours, and average retirement ages. After doing some math, it concluded that Austria was the happiest country overall. 

Austria has been ranked as the happiest nation, with an index score of 7.26 out of 10. The country in Central Europe is in the top 10 for four of the six criteria we examined, indicating a generally good performance," the researchers said in their report. "It scores particularly high for its retirement age of 62.5, sharing second place for the factor." 

Slovenia comes next, with a Happiness Score of 72, which helped them place second. "At 62, the country has the lowest retirement age. With a safety index score of 77.3 out of 100, it ranks third on the list and is among the safest nations. It has a 7.20 out of phrazle 10 overall rating, the researchers continued. 

With a score of 7.15, Switzerland finished in a tight third place, owing to both its exceptional safety record and its ranking among the top five countries for salaries, with an average yearly pay of $72,993. South Korea, which comes in at number four, is followed by the Netherlands, Germany, Denmark, Luxembourg, Iceland, and Japan in the top ten. 

Greece, along with Luxembourg, Slovenia, and South Korea, has an incredibly low retirement age of 62, which makes it a top choice for those who want to not only retire early from work but also enjoy a vacation. This fact was also noted by the researchers.
