The same is true of China, so that half of the world’s people live in a country or area where the population is falling. The fertility rates in North America and Europe have fallen below 2.1, the threshold for natural population replacement. The contrast with richer countries is dramatic. The countries of sub-Saharan Africa are at an early stage of the transition, where child mortality and life expectancy indicators are improving but the average fertility rate of 4.6 children per woman remains high. The headlong rush towards the UN’s projection of a peak global population of almost eleven billion masks a complex mix of underlying trends. When the birth rate finally stabilises at its lower level, a country’s population profile will progressively age as the “baby boom” generation matures.Ĭountries around the world find themselves at very different points within the demographic transition. The consequence is a rapid rise in national population. In the transition from high to low fertility and mortality rates, the latter has invariably outpaced the former.
