Sub-Saharan Africa, meanwhile, will triple in size to some3 billion people, with Nigeria alone expanding to almost 800 million in 2100, second only to India's 1.1 billion. At the other end of the spectrum, 2.37 billion people -- more than a quarter of the global population -- will be over 65 years old by then. In Nigeria, by contrast, the active labour force will expand from 86 million today to more than 450 million in 2100. Until now, the United Nations -- which forecasts 8.5, 9.7 and 10.9 billion people in 2030, 2050 and 2100, respectively -- has virtually had a monopoly in projecting global population. "Continued global population growth through the century is no longer the most likely trajectory for the world's population."
