The Economist: Africa's population: The lesson from Sodom and Gomorrah
CAREFULLY stepping round another heap of fetid refuse in Sodom and Gomorrah, it is easy to despair of Africa’s future. Accra’s notorious slum is aptly named. Here, about 30,000 families (no one knows for sure how many) crowd into a warren of hastily thrown-together shacks on the fringes of Ghana’s capital: there is no power, sewerage or running water, diarrhoea and other diseases are rife and deadly fires rapidly take hold. It seems to contain all that is wrong with modern Africa—too many people, deep poverty and the failure of inept or corrupt governments to do anything to help. Yet Sodom and Gomorrah also has a more hopeful story to tell.
Africa is undergoing a “demographic transition”. As our briefing shows (see article), African women are now following their sisters in Asia and the rich world by bearing steadily fewer children. Admittedly, Africa is lagging behind Asia by about 20 years, and the continent’s fertility rates are still high, but the trend is clear. In Mozambique in 1950 a woman had, on average, 6.5 children over her lifetime; now she has five. In Ethiopia the figure has dropped from seven to five; in Côte d’Ivoire it has almost halved from its peak; in Botswana it has more than halved. The only exceptions are war-torn places such as Congo. ...
...In Latin America and Asia this transition yielded a huge economic gain, called the “demographic dividend”. As birth rates decline, the proportion of children shrinks and the working-age population bulges, as is happening now in Africa. That can kick-start industrialisation. Factories employ low-skilled farmers fresh from the country, which increases productivity and prosperity, which creates demand, and so it goes on. Some studies reckon that demography explains as much as a third of Asia’s economic growth. ...
