Population ageing in the Middle-East and North Africa: Research and policy implications

The United Nations' World Population Prospects 2019 reported that not only all countries are experiencing an increase in their numbers and percentages of older persons, some nations are experiencing a drastic increase at a much faster pace. The world’s population continues to grow, albeit at a slower pace than at any time since 1950, owing to reduced levels of fertility. From an estimated 7.7 billion people worldwide in 2019, the medium-variant projection indicates that the global population could grow to around 8.5 billion in 2030, 9.7 billion in 2050, and 10.9 billion in 2100. It is noteworthy that with a projected addition of over one billion people, countries of sub- Saharan Africa could account for more than half of the growth of the world’s population between 2019 and 2050, and the region’s population is projected to continue growing through the end of the century. By contrast, populations in Eastern and South-Eastern Asia, Central and Southern Asia, Latin America and the Caribbean, and Europe and Northern America are projected to reach peak population size and to begin to decline before the end of this century. Two-thirds of the projected growth of the global population through 2050 will be driven by current age structures and would occur even if childbearing in high-fertility countries today were to fall immediately to around two births per woman over a lifetime. This is true because the large population of children and youth in such countries will reach reproductive age over the coming few decades and begin to form families and bear children of their own.peer-reviewe
