 The Human Development Index (HDI), published annually by the UN, ranks nations according to their citizens’ quality of life rather than strictly by a nation’s traditional economic figures. The criteria for calculation ranking include life expectancy, educational attainment, and adjusted real income. The most livable countries in 2006 were Norway, Iceland, Australia, Ireland and Sweden.
