A UN report says that South Koreans will have the longest lives in the world by 2100.

The UN’s Department of Economic and Social Affairs said in a report on world population that South Koreans’ average life expectancy will increase to 88-point-four years between 2045 and 2050 and to 95-point-five years by 2100.

The report also predicted that a surge in the population of Africa and other developing countries will increase the global population to over nine-point-six billion by 2050 and eleven billion around 2100.

This projection is up eight percent from the UN’s 2011 prediction at ten-billion-100-million. The revision is attributable to a slower-than-expected drop in Africa’s birthrate.

Africa is currently home to one-billion-100 million people, a number expected to nearly quadruple to four-billion-200-million by 2100.
