Pro-natalism - what can we learn from Israel?

As countries have become more prosperous and educated, their fertility rates have tended to decline, to the point that Israel stands alone as the only developed country to have a fertility rate above replacement.

Mars, of course, will be a highly educated and developed world from the start, so it will not be immune to the anti-natal effect of prosperity. If space colonisation is to be considered a success, it can't be a population sink that relies on continued immigration from Terra to keep numbers up. We will have to learn from the Israelis about how to promote fertility. … c-miracle/

Want to raise national fertility rates?   Close down the abortion clinics and restrict access to the contraceptive pill.  The contraceptive pill was a disaster for national fertility.  Not because it allowed sex without fear of pregnancy.  It is precisely because it allowed unprotected sex without fear of pregnancy.  It allowed the full intimacy of unprotected sex,  whilst denying the biological consequences of unprotected sex.  Women crave that intimacy and the pill allowed them to avoid the consequences.

Interested in space science, engineering and technology.

Re: Pro-natalism - what can we learn from Israel?

It's an interesting question. If we want to grow the population of Mars we should be encouraging large families.

But on the other hand the strong likelihood is that most women on Mars will be highly educated and highly independent-minded - precisely the sort of women who don't have large families on Earth.

One lesson I think we could take from Israel, from the Kibbutz movement, is to provide full childcare. In the Kibbutz movement the commune took over the lion's share of the responsibility for raising the child. However, over time the Kibbtuz has tended to be supplanted by more traditional family structures. People like to feel part of a close family, not part of a social commune.

Of course there is a bigger issue of whether we can procreate successfully on Mars. The answer is probably yes - even if we have to resort to  artificial 1G environments (maybe in LMO).

Scientists have been able to keep premature lambs alive in artificial wombs: … r-4-weeks/

One day it may be possible to transfer a human foetus at an early stage in pregnancy to an artificial womb, so minimising the difficulties for the mother in terms of pursuing her career.

It might be possible to use fertility treatment methods to create multiple pregnancies - maybe non-identical twins would be standard.

Perhaps there could be strong financial incentives for large families as well as extended child care. A woman might be prepared to have two twin pregancies - one in her mid 20s and one in her mid 40s.
