Today, the global population has reached 8 billion!

From 7 billion to 8 billion, how long did it take?

While it took the global population 12 years to grow from 7 to 8 billion, it will take approximately 15 years —?until 2037 —?for it to reach 9 billion, a sign that the overall growth rate of the global population is slowing.

How many people will there be in the world at most?

The?global population will?start?to peak?at around 10.4?billion people in the?2080s and remain at that level?until?2100.

The University of Washington report estimated that the global population would peak in 2064 at 9.7 billion before declining to 8.8 billion in 2100.

Now, where is the world's largest population?

Currently, China and India?are joint-most populated countries in the world, with?1.4 billion people each. But based on?UN projections, India?will surpass China?for the first time in 2023.

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.

Will the population continue to grow?

Yes, but the growth rate is slowing down. The growth rate of the world population during 1962-1965 was 2.1% per year. Since then, the growth rate has dropped sharply and will be less than 1% in 2020. By 2050, the annual growth rate of global population may drop to about 0.5%.

In addition, in 2021, the average fertility rate of the global population will be 2.3, that is, every woman will have 2.3 children in her lifetime. In 1950, the fertility rate will be 5, and it is expected to drop to 2.1 in 2050.

How long do people live?

The global average life expectancy continues to increase. In 2019, the global average life expectancy was 72.8 years, 9 years more than in 1990; By 2050, the average life expectancy is expected to reach 77.2 years.

However, the combination of increasing life expectancy and declining fertility will intensify the aging of the population. The proportion of people over 65 years old in the total population will be 10% in 2022 and will rise to 16% by 2050.

In these difficult times, we would do well to remember the words of one of humanity's wisest observers, Mahatma Gandhi: "The world has enough for everyone's need – but not everyone's greed."
