The happiness level of countries in the world (2)

Mental health problems such as clinical depression and anxiety have a huge impact on people's well-being. Mental health issues are often ignored by policy-makers, the study found.

On average, people in more than 150 countries rate their happiness as a 5.1 on a scale of 0 to 10:

       -      61 countries saw their happiness improve over the years;

       -    41 countries have become unhappier.

Sub-Saharan Africa and Latin America are becoming happier overall, while industrial nations report less well-being.

This kind of research conclusions could help public policy-makers tweak their policies to impact those factors, such as cracking down on corruption, to boost people's happiness.

At the same time, happy citizens also make for better countries. So, the happiness results for people who live longer, more productive lives, have higher earnings and are better citizens.
