In a Washington Post feature titled 'Africa Hangs in the Balance,' Bill Gates argued that sub-Saharan Africa's rapid population growth — projected to double to 2.5 billion by 2050 — without equivalent investment in health and education would produce both a humanitarian catastrophe and unprecedented migratory pressure on the rest of the world. He described Africa as being at a demographic crossroads: with the right investments in child survival, girls' education, and agricultural productivity, the continent could follow Asia's development trajectory; without them, the numbers of young people without prospects — and without the ability to create stable lives at home — would drive displacement on a scale the international system was not equipped to manage.
