By 2300 the United Nations forecasts that the global population will be just under 9 billion. World population is expected to rise, peak and then decline slightly between 2050 and 2300. The highest long term population growth is predicted for Africa. Africa is currently underpopulated and has the lowest life expectancies. Other regions' populations are predicted to stay level or decline. Between 2050 and 2300 the areas currently known as India, China, the United States and Pakistan maintain their ranked order as having the world's highest populations. The numbers shown here are estimates - based on predicted future behaviours.
