Faces Of Poverty

The 2007 World Bank report "Global Economic Prospects" predicts that in 2030 the number living on less than the equivalent of $1 a day will fall by half, to about 550 million. An average resident of what we used to call the Third World will live about as well as do residents of the Czech or Slovak republics today. Much of Africa will have difficulty keeping pace with the rest of the developing world and even if conditions there improve in absolute terms, the report warns, Africa in 2030 will be home to a larger proportion of the world's poorest people than it is today.
The reason for the faster economic growth in East Asia and South Asia is a result of their relative backwardness, in a phenomenon called the convergence hypothesis or the conditional convergence hypothesis. Because these economies began modernizing later than richer nations, they could benefit from simply adapting technological advances which enable higher levels of productivity that had been invented over centuries in richer nations.
