The changing balance of world population

I came across these two maps on the Brilliant Maps web site,  They show the changing balance of world population over the past century.

In 1900, the population of North America exceeded the population of Latin America.  Now it is the reverse.

In 1900, the population of Europe vastly exceeded the population of Africa.  Now Africans are more numerous.

The population of present-day China is only slightly less than the population of the whole world in 1900.

To get a better idea of the absolute increase, you’d need to enlarge the maps, and enlarge the bottom map a little more so that the sizes of the little squares (each one equivalent to 500,000 people) are equal in size.

The population of China has more than tripled since 1900, but the population of the United States has quadrupled and there are five times as many Canadians and Australians.  There are more than 10 times as many Mexicans, Brazilians and Nigerians as in 1900 and more than 20 times as many Ethiopians.

A nation can be populous and weak, like India and China in 1900 and Nigeria and Ethiopia today.  Nevertheless, there is a relationship between population and power in the long run.

Bertrand Russell wrote somewhere that if there is to be world peace, nations must agree to limit their populations as well as their armaments.  He had a good point, but I’m not sure such agreements are feasible.

There seems to be a universal demographic transition.  When modern medicine and agriculture reduce death by disease and famine, the death rate falls and population increases rapidly.  When living standards rise, contraception is available and women are emancipated, the birth rate falls, eventually falling below replacement rate.  Governments don’t seem to be able to affect this very much.

Here’s another map, which gives current population in greater detail.
