World Happiness Report 2013
"The World Happiness Report 2013 was launched at a major international workshop on September 8th.
It reveals fascinating trends in the data judging just how happy countries really are. On a scale running from 0 to 10, people in over 150 countries, surveyed by Gallup over the period 2010-12, reveal a population-weighted average score of 5.1 (out of 10). Six key variables explain three-quarters of the variation in annual national average scores over time and among countries. These six factors include: real GDP per capita, healthy life expectancy, having someone to count on, perceived freedom to make life choices, freedom from corruption, and generosity.
The Report shows significant changes in happiness in countries over time, with some countries rising and others falling over the past five years. There is some evidence of global convergence of happiness levels, with happiness gains more common in Sub-Saharan Africa and Latin America, and losses more common among the industrial countries. For the 130 countries with data available, happiness (as measured by people’s own evaluations of their lives) significantly improved in 60 countries and worsened in 41.
The Report also shows the major beneficial side-effects of happiness. Happy people live longer, are more productive, earn more, and are also better citizens. Well-being should be developed both for its own sake and for its side-effects."
