Birth rates and the global balance of power

A forecast and not a fact

A forecast and a possibility but not a certainty

Also a possibility but not a certainty

It is a good thing, not a bad thing, that birth rates are falling worldwide.  If things continue as they are, world population growth will level off by the end of the century.

But the fact that they are not falling at the same rate in every country changes the world balance of power, as Indians outnumber Chinese and Africans outnumber Europeans.

Bertrand Russell once wrote that if there is to be peace in the world, nations will have to negotiate limits on their populations as well as limits on their armaments.

I don’t see how that would be feasible without nations also agreeing to totalitarian Chinese-style birth regulations.  The alternative is to wait for the “demographic transition” to click in.  Help people achieve a better life, provide women with reproductive rights and knowledge and wait for population to level off as it is doing in the developed world.

World on track for zero population growth

Much of the world is on track for zero population growth.  Birth rates in many countries are at the replacement rate of 2.1 children per average couple, or lower.

brazila01gra1The change, in my opinion, has come about because (1) knowledge and availability of birth control are widely available, (2) women are emancipated and have control over their bodies and (3) people are raised far enough out of absolute poverty that they think it is better to have a small number of prosperous, well-educated children than to have many children.

I think that, in the long run, Muslims and Hindus will be as willing to practice contraception as Catholics have proved to be.

The young nations and the aging nations

I think the leveling off of population growth is a good thing.  There is a limit to how many people the earth can support.  I don’t claim to know what that limit is, but it will be passed at some point unless population growth is leveling off.

demographic transitionThe good news is that this is starting to happen.  The problem is that it is not happening in every nation at once.

Some nations have low birth rates and an aging population that is growing in relation to the working-age population.  Other nations have high birth rates and a young population who can’t all find jobs.

Should there be more immigration from the growing young nations to the static older nations?

What happens to the world balance of power when the population of some nations is static and the population of others grows?  If present trends continue, India will have a larger population than China.  Mexico could become a more populous nation than the USA.  What then?

Bertrand Russell years ago wrote that in order to achieve world peace, nations needed to limit their populations as well as limit their armies and armaments.  Is that possible?

Demographers say that a nation’s population growth starts to level off when women are emancipated enough to be able to decide whether or not to have children, and when a nation reaches a level of prosperity such that parents think their security in old age is better with a few well-educated and well-off children than with many poor children.

I hope this comes true for the whole world.  Expressing this hope is as close as I can come to answering the questions I asked.

What do you think?
