Each year, the UN investigates the reported level of happiness in 
countries around the world. This year, in the sixth World Happiness 
Report, more than 150 countries were included in the study.
The UN
 report evaluates the happiness levels in a country by assessing the 
population by means of a survey in which individuals report their own 
life evaluations. The following variables are used to judge a country’s 
level of happiness:
- GDP per capita
 
- Social support
 
- Healthy life expectancy at birth
 
- Freedom to make life choices
 
- Generosity
 
- Absence of corruption
 
Social support refers to whether a person feels that they have 
relatives or friends who they can count on, should they find themselves 
in a troublesome situation. Freedom to make life choices is based on the
 binary response to the question “Are you satisfied or dissatisfied with
 your freedom to choose what you do with your life?” The generosity 
factor refers to whether individuals donate to charity.
The following countries make it into the top ten happiest in the world.
- Finland
 
- Norway
 
- Denmark
 
- Iceland
 
- Switzerland
 
- Netherlands
 
- Canada
 
- New Zealand
 
- Sweden
 
- Australia
 
When it comes to the happiness of 
foreign-born nationals compared to that of locals, Finland tops the list
 again. Denmark, Norway, Iceland and New Zealand make up the rest of the
 top five.
In this particular ranking, the Netherlands doesn’t 
hold onto its sixth place. Instead, it falls out of the top 10 to 11th 
place. Coming in just above the Netherlands is Mexico. The top 10
