Ethiopia, Nigeria, and Egypt are primed for a global population increase in 2050 as the world’s population is expected to exceed 8 billion this year.
According to the most recent UN forecasts, the world’s population might reach roughly 8.5 billion in 2030, 9.7 billion in 2050, and 10.4 billion in the 2080s. The population is anticipated to remain stable until the year 2100.
However, according to the annual World Population Prospect study, which was released on Monday to coincide with World Population Day, the global population is expanding at its slowest rate since 1950, with a drop to less than 1% in 2020.
The world should expect to see far more grey hairs by 2050: by then, it is expected that the number of persons aged 65 years or over worldwide will be more than twice the number of children under the age of five, and about the same as the number under age 12.
Further reductions in mortality are projected to result in average global longevity of around 77.2 years in 2050. Yet in 2021, life expectancy for the least developed countries lagged seven years behind the global average.
More than half of the projected increase in the global population up to 2050 will be concentrated in eight countries: the Democratic Republic of the Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines and the United Republic of Tanzania.
Countries of sub-Saharan Africa are expected to contribute more than half of the increase anticipated through 2050.
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.
