According to World Population Prospects 2024: Summary of results, the world's population is expected to peak in the mid-2080s, growing over the next 60 years from 8.2 billion people in 2024 to around 10.3 billion in the mid-2080s. 2080s, and then return to around 10.2 billion by the end of the century, the Xinhua news agency reported Thursday.
The size of the world's population in 2100 is now expected to be six percent smaller (or 700 million fewer) than predicted a decade ago.
"The demographic landscape has evolved a lot in recent years," said Li Junhua, Under-Secretary-General for Economic and Social Affairs.
"In some countries, the birth rate is now even lower than expected and we are also seeing slightly faster declines in some high fertility regions."
"The earlier and lower peak is a hopeful sign. This could mean a reduction in environmental pressures from human impact due to lower aggregate consumption. However, slower population growth will not eliminate the need to reduce the average impact attributable to the activities of each individual person." He noticed it.
The previous demographic spike is due to several factors, including lower fertility levels in some of the world's largest countries. According to the report, globally, women are having one fewer child, on average, than in 1990.
In more than half of all countries and areas, the average number of live births per woman is less than 2.1 (the level required for a population to maintain a constant long-term size without migration) and almost a fifth of All countries and areas now have "ultra-low" fertility, with fewer than 1.4 live births per woman over her lifetime.
Early pregnancies remain a challenge, especially in low-income countries.
In 2024, 4.7 million babies, or about 3.5 percent of the total worldwide, were born to mothers under 18 years of age. Of these, some 340,000 were born to children under 15 years of age, with serious consequences for health and well-being. -Be of both young mothers and their children.
The report found that investing in the education of young people, especially girls, and raising the age of marriage and having the first child in countries where these problems occur early will have positive results for health, educational attainment and participation in the community. women's workforce. These efforts will also help curb population growth and reduce the scale of investments needed to achieve sustainable development, while ensuring that no one is left behind.
Over the past three decades, mortality rates have decreased and life expectancy has increased significantly.
After a brief decline during the Covid-19 pandemic, life expectancy at birth around the world is increasing again, reaching 73.3 years in 2024, up from 70.9 years during the pandemic. By the end of the 2050s, more than half of all global deaths will occur at age 80 or older, a substantial increase from 17 percent in 1995.
By the end of the 2070s, the number of people aged 65 and over is projected to exceed the number of children (under 18), while the number of people aged 80 and over is projected to be greater than number of babies (under one year old) already by the mid-2030s.
According to the report, even in countries that are still growing rapidly and have a relatively young population, the number of people aged 65 and over is expected to increase over the next 30 years.
