White countries tend to be happier

The 10 happiest countries are Denmark, Finland, Norway, Netherlands, Canada, Switzerland, Sweden, New Zealand, Australia and Ireland. The unhappiest countries are Togo (ranked last), Benin, Central African Republic, Sierra Leone, Burundi, Comoros, Haiti, Tanzania, Congo and Bulgaria. Different groups have asked different questions to measure happiness. In the widest such survey, Gallup asked people to rate their lives from 0 to 10. It found huge differences in global happiness: More than a third of Europeans ranked themselves an 8 or higher. Less than 5% said so in sub-Saharan Africa. It's not hard to notice that the unhappiest countries are also some of the poorest. The four happiest countries have incomes that are 40 times higher than the four unhappiest countries. People can also expect to live 28 years longer in the happiest nations.
