Recent reductions in fertility have led to a “demographic dividend” in Latin America and the Caribbean as the latest United Nations projections suggest that the world’s population could grow to around 8.5 billion in 2030 and 9.7 billion in 2050, before reaching a peak of around 10.4 billion people during the 2080s.

It said that the population is expected to remain at that level until 2100.

The annual study, released on Monday to coincide with World Population Day (WPD), also notes that the global population is growing at its slowest rate since 1950, having fallen to less than one per cent in 2020.

Fertility, the report declares, has fallen markedly in recent decades for many countries: today, two-thirds of the global population lives in a country or area where lifetime fertility is below 2.1 births per woman, roughly the level required for zero growth in the long run, for a population with low mortality.

In 61 countries or areas, the population is expected to decrease by at least one per cent over the next three decades, as a result of sustained low levels of fertility and, in some cases, elevated rates of emigration.

The UN notes that in most countries of sub-Saharan Africa, as well as in parts of Asia and Latin America and the Caribbean, recent reductions in fertility have led to a “demographic dividend”, with a rise in the share of the working age population (25 to 64 years), providing an opportunity for accelerated economic growth per capita.
