Furthermore, the report said that the world population could increase to about 8.5 billion by 2030 and 9.7 billion by 2050.
United Nations Secretary-General Antonio Guterres said, “This year’s World Population Day is a milestone. The world population passing eight billion is an opportunity to celebrate our diversity and recognize our humanity. Life expectancy has been extended, maternal and child mortality rates have been dramatically reduced, and health has improved.” He said.
At the same time, it also reminds us of our responsibility to take care of our planet Earth. It is also a moment to reflect on where we are still losing our commitment to each other, points out Antonio Cattares.
A UN report on world population predicts that 61 countries will experience a population decline of one percent or more between 2022 and 2050 due to factors including low fertility. The Democratic Republic of the Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines, and the United Republic of Tanzania are the eight countries that are projected to grow in population, and these countries alone are expected to account for more than half of the world’s population growth by 2050.
Global life expectancy reached 72.8 years in 2019, an increase of 9 years compared to 1990. This is expected to further increase and global average life expectancy will rise to 77.2 years by 2050. However, the average in least developed countries is 7 years behind the world average.
World population reached 4 billion in 1974. It doubled over the next 48 years and now stands at 8 billion. However, the next doubling is unlikely to happen during such a period. Although the world’s population will continue to grow over the next few decades, fewer deaths will be due to increased life expectancy, according to UN population data.
This can be seen to reduce birth rates. Also, the report says, as birth rates continue to decline, the population will grow slowly this century and then begin to decline. Meanwhile, the UN report points out that the number of elderly people is also increasing due to the increase in life expectancy. In 1974, the median age of the world’s population was 20.6 years, meaning that half of the world’s population was under 22.2 years; The other half are older than that age. The current global median age is 30.5 years.
The world population is now 8 billion. It is likely to exceed 10 billion before 2100. But UN population projection data and many experts agree that the world’s population will not continue to grow. They predict that the population will peak in this century and then begin to decline. They also predict that the population will gradually increase to 10.4 billion in 2086.
