Specifically addressing this, which I realize is not the main point, but it is “in play,” I think. I’m going to address the main point, though, and not flog this.
Global warming is going to cause population shifts. Countries that are still habitable in 50 years are going to see population increases from immigration, and that’s good, because the biggest problem with not having enough people to replace the current population is that there won’t be enough people do eldercare.
Eldercare is not the greatest job, in general, since lots of the tasks involve bedpans, bathing people with limited mobility, and dealing with people with degrees of dementia.
Immigrants usually take jobs that the homebred population doesn’t want, and, the country doesn’t have as much invested in immigrants, like 13 years of public education.
Extrapolating current problems to the future, and saying “we need to increase the birthrate” is short-sighted, I think.
So, I think you can increase the population without increasing the birthrate, except in countries that are becoming uninhabitable.
Just as a mental exercise, how do you increase the birthrate? yes, not educating women in general, and the whole population specifically about birth control will increase the birthrate.
But it will also increase women and infant mortality. The younger population will be able to care for the elderly partly because there will be fewer elderly. An ignorant population means one with a lower life expectancy.
What you want, I think, is not simply to increase the birthrate, but to increase the healthy birthrate. In other words, you are looking for a sweetspot where there are lots of babies born, they are born full-term and healthy, and they survive infancy.
You don’t want to increase the populations of newborns-- you want to increase the population of 5-yr-olds. Once a person has made it to 5, they are statistically likely to make it to adulthood.
For this, you need free, quality pre-natal care, free help for anyone who needs it in caring for babies, encouragement of breastfeeding, but free quality formula for those who simply cannot.
And destigmatizing of motherhood. Men can be fathers, plus something else, and that is normal. It needs to be normal for women too.
Also, you need to make it illegal to touch a pregnant women’s belly without asking. Seriously. Knock that shit off.
