On UN projections between 2015 and 2050, the world population will grow by nearly 2.38 billion people, from 7.35 billion to 9.73 billion. Although this 32% growth is a big increase, it marks a slowdown from the 66% growth rate recorded in the preceding 35 years (1980-2015). Total Fertility Rates (TFRs) have come down all over the world and are expected to continue falling.
About half of the 2.38 billion increase will take place in sub-Saharan Africa and nearly 40% in Asia. India is the biggest contributor with a net addition of 394 million, followed by Nigeria (216m), Pakistan (120m), DR Congo (118m) and Ethiopia (89m). By 2050, all of these countries will feature in the top 10 populations by size, a list that will include the United States (expected to rank fourth) but not one European country. Outside of Africa and Asia ex-China, regional populations will be growing slowly (the Americas), stagnating (China, Europe), or receding (Japan, Eastern Europe). Read more
A recent report published jointly by the World Bank and by Agence Française de Développement highlights the challenge of realizing Africa’s promised demographic dividend. The title Africa’s Demographic Transition: Dividend or Disaster? (see footnote 1) sums up the authors’ thesis that the dividend is not an automatic result of falling fertility ratios (TFR).
Instead, falling TFRs open a window of opportunity which can lead to a demographic dividend when governments and the public sector implement the requisite steps to capitalize on this opportunity. Lower child mortality usually leads to falling fertility ratios and improvements in women’s health. But most important among concurrent or subsequent initiatives are investments in education, and the provision of sufficient jobs to a booming working-age population. Read more
