Nigeria named the worst place to be born in 2013

Warren Buffett, probably the world's most successful investor, has said that anything good that happened to him could be traced back to the fact that he was born in the right country, the United States,

at the right time (1930). A quarter of a century ago, when The World in 1988 light-heartedly ranked 50 countries according to where would be the best place to be born in 1988, America indeed came top. But which country will be the best for a baby born in 2013? To answer this, the Economist Intelligence Unit (EIU), a sister company of The Economist, has this time turned deadly serious. It earnestly attempts to measure which country will provide the best opportunities for a healthy, safe and prosperous life in the years ahead.

Its quality-of-life index links the results of subjective life-satisfaction surveys—how happy people say they are—to objective determinants of the quality of life across countries. Being rich helps more than anything else, but it is not all that counts; things like crime, trust in public institutions and the health of family life matter too. In all, the index takes 11 statistically significant indicators into account. They are a mixed bunch: some are fixed factors, such as geography; others change only very slowly over time (demography, many social and cultural characteristics); and some factors depend on policies and the state of the world economy. A forward-looking element comes into play, too. Although many of the drivers of the quality of life are slow-changing, for this ranking some variables, such as income per head, need to be forecast. We use the EIU's economic forecasts to 2030, which is roughly when children born in 2013 will reach adulthood.
