The World Population

We Never Know

-The world population reached one billion in 1804.
-It was another 123 years before it reached two billion in 1927.
-It took only 33 years to reach three billion in 1960.
-And it took only 62 years to go from three billion to eight billion in 2022.

We currently stand at eight billion. However they are predicting it will take nearly 80 years to hit eleven billion.

Are they underestimating?

World population projected to reach 9.8 billion in 2050, and 11.2 billion in 2100

As I recall, they're predicting a slight decline in birth rates (based on current trends) which will slow the growth a bit, which is why they estimate it will take longer to reach 11 billion.

But it's hard to predict anything. By 2100, the world population could be zero.

11bn is predicted to be the maximum population. So it's not just slowing down the rate of increase, it's bringing it to a halt.

Once women have on average 2.2 children, you have a stable population with no increase. In many mature economies, the birth rate has been below this level for some time.

Thinking of Europe...when all the older generations die, we will be reduced to half, numerically.

Worldwide today, as I post this, there have been near twice as many births than deaths.

Births -116,550
Deaths -58,312

Europe grew by nearly 1,000,00 in 2020 but I didn't see births-vs-deaths.
It may be because of people moving/migrating in

Oddly enough, from 1955 and up, Generation X had the largest % increase from 1965-1970
3,700,437,046 -2.07 % - 72,170,690

Why, then, have you chosen to cut off the next column to the right, which actually tells you the answer?

In fact the net increase in Europe is indeed caused by net inward migration. Without it, the population would be falling. The same chart also includes the fertility rate, which has been below the 2.2 per woman rate needed to maintain the population since the end of the 1970s.

May be you should ask instead of assume. You see when you are on a phone and take a screenshot, you can only get so much of the picture.

They are overestimating. The world population will not hit 11 billion.

There are so many things that affect population growth, some of which could be catastrophic, thus I cannot even begin to buy into any estimates. However, I do believe we are already seriously overpopulated and hell bent on destroying much of the planet.
