After peaking in the early 1960s, that changed population growth According to Rachel Snow of the United Nations Population Fund (UNFPA), the pace has now slowed significantly. While the world population grew at an annual rate of 2.1 percent between 1962 and 1965, growth dropped to less than one percent in 2000. Due to the declining birth rate, the growth rate could drop to around 0.5 percent by 2050, according to UN estimates.

10.4 billion by 2080

Taking into account rising life expectancy and the number of women of childbearing age, the UN predicts growth to 8.5 billion in 2030, 9.7 billion in 2050 and a peak of around 10.4 billion around 2080.

Other experts have calculated other numbers. In a study published two years ago, the US Institute for Health Measurement and Evaluation (IHME) predicted that the peak would be reached by 2064 and be below ten billion. The reason is different assumptions birthrate. In 2021, according to UN statistics, every woman had 2.3 children in her lifetime. By 2050, the rate should therefore drop to 2.1.

Almost every sixth person is over 65 years old

An important factor in population growth is average Length of life. This is steadily increasing – from 63.8 years in 1990 to 72.8 years in 2019. By 2050, the UN expects an average life expectancy of 77.2 years.

Combined with the declining birth rate, this means that the share of people over 65 in the total population will increase. The share is currently ten percent. It is expected to increase to 16 percent by 2050. This increases the burden on state pension systems, increases the need for care for the elderly, and at the same time fewer young workers are available.

Eight states account for half of the increase

There are large differences in population development between individual regions of the world. That’s what she expects ONEthat by 2050, more than half of population growth will come from eight countries: India, Nigeria, Egypt, the Democratic Republic of the Congo, Ethiopia, Pakistan, the Philippines and Tanzania.

The average age in different regions is also higher than ever before: it is currently 41.7 years in Europe and 17.6 years in sub-Saharan Africa.

India has overtaken China

According to UN forecasts, the world’s two most populous countries, China and India, are likely to switch places on the podium as early as next year. India’s total population will grow to around 1.4 billion by 2023 and 1.7 billion by 2050. On the other hand, China’s population is projected to drop to 1.3 billion by 2050.
