Those looking for greater happiness and satisfaction in life should head to northern Europe, but steer clear of Egypt and countries worst hit by the eurozone crisis, according to the 2013 World Happiness Report released Monday by Columbia University’s Earth Institute.

Denmark, Norway, Switzerland, the Netherlands and Sweden are the world’s happiest countries, according to the survey of 156 countries. Rwanda, Burundi, the Central African Republic, Benin and Togo — all nations in Sub-Saharan Africa — are the least satisfied with their lives, the report said.

The United States came in at number 17 in the world in terms of overall happiness, but it still lags behind Canada (6), Australia (10), Israel (11) the United Arab Emirates (14) and Mexico (16), according to the Earth Institute.

The report ranks the United Kingdom as the 22nd happiest country in the world. Other major nations included Germany (26), Japan (43), Russia (68) and China (93).

Governments seeking to improve the happiness of their populations should spend a higher proportion of their health budgets on mental illness, which is the single biggest “determinant of misery” in countries assessed, the study authors said.

“If we want a happier world, we need a completely new deal on mental health.”
