Latest projections from the United Nations 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.
In a statement by the UN to mark the world population Day, it noted that the population is expected to remain at that level until 2100.
The annual World Population Prospect report, released on Monday to coincide with World Population Day, also notes that the global population is growing at its slowest rate since 1950, having fallen to less that 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 COVID-19 pandemic has had an effect on population change: global life expectancy at birth fell to 71 years in 2021 (down from 72.9 in 2019) and, in some countries, successive waves of the pandemic may have produced short-term reductions in numbers of pregnancies and births.
“Nevertheless, the cumulative effect of lower fertility, if maintained over several decades, could be a more substantial deceleration of global population growth in the second half of the century.
