摘要：Between the early 1950s and the present, the global fertility transition has been nearly universal in the developing world. However, as of 2017, two countries out of the 190 countries for which the United Nations provides fertility estimates had not yet met the conventional criterion for establishing the onset of the fertility transition (a decline of at least 10 per cent from peak fertility), and another five countries did so only very recently. These are the laggards in the global fertility transition. The countries are all in sub-Saharan Africa: Chad, the Democratic Republic of the Congo, Equatorial Guinea, The Gambia, Mali, Niger, and Somalia. This paper first reviews the fertility history of these seven countries, and subsequently provides data on the timing and pace of the global fertility transition in the four major developing regions: Asia, Latin America and the Caribbean, Northern Africa, and sub-Saharan Africa. It then explores potential reasons for the slow emergence of fertility decline in each country. The paper concludes with a discussion of each country’s prospects for fertility decline, which generally are weaker than those in the projections of the United Nations.
