According to the United Nations "World Population Prospects 2022" report, the global population will reach 8 billion by the 15th of this month.
This number will continue to grow over the next few decades, but at a slower pace and with regional differences.
Due to rising life expectancy and population of reproductive age, the United Nations projects that the global population will grow to around 8.5 billion by 2030, 9.7 billion in 2050, peak at around 10.4 billion in the 2080s, and remain at this level until 2100.
On the other hand, global average life expectancy continues to increase, combined with declining fertility rates, which will exacerbate the aging of the population and increase the demand for elderly care, which will affect the labor market and national pension systems.
According to United Nations data, the global average life expectancy in 2019 was 72.8 years, 9 years more than in 1990; by 2050, the average life expectancy is expected to reach 77.2 years.
The proportion of the population over the age of 65 in the total population will rise from 10% in 2022 to 16% in 2050.
The United Nations predicts that by 2050, more than half of the world's new population will be concentrated in eight countries: Congo (DRC), Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines and Tanzania.
According to the World Population Prospects 2022 report, India is expected to become the most populous country as early as 2023 and reach 1.7 billion by 2050.
