An update of world population forecasts
Data for South America were included in the analysis just to show what is happening in a less populated, modestly growing part of the world. But even in South America the forecasts have changed significantly over time. The population of the region in 2050 will be 78 million higher than predicted in 1994 but 30 million less than forecast in 2000. The population of the region increases by 28 percent between 2010 and 2050, almost as large a percentage increase as is forecast for India (34 percent).
The data still show that most of the population growth over the next 40 years will be in poor countries. The countries with the biggest increase in population in order are India, Nigeria, Ethiopia, Pakistan, Congo, the U.S., Tanzania, Indonesia, Uganda and the Philippines. These 10 countries account for more than half of the total world population increase over the period.
