United Nations World Development Index

Norway ranks number one on the UN Human Development Index.To the surprise of absolutely no one, Norway has been declared the world’s happiest country. Just as unsurprising, the Democratic Republic of Congo came last.The United Nations Human Development Index 2011 measures happiness in different countries based on factors such as income, education, health, life expectancy, economy, gender equality and sustainability. To be more accurate, one would say this measures the quality of life. It goes beyond income to include basic measures like education and health.
Bhutan, the only country that gauges its progress by measuring its people’s happiness rather than economic contributions, came a rather lowly 141. This study is much more empirical than the Gross National Happiness (GNH) Index you will find in Bhutan, which is quite subjective.
Just missing out on a top 10 spot was Switzerland in 11th place. The United States came fourth while the United Kingdom came 28th, below Hong Kong (13th), Korea (15th), France (20th), Singapore (26th) and the Czech Republic (27th).
