I have followed the Fertility Crisis a fair bit over the last decade, before it became the hot topic it has become more recently. Thee is a lot of discussion about why women aren't having children, why men aren't getting married, whether it's too expensive, too socially unpopular, with twenty theories for each of these. I have engaged in the discussion and highlighted a few possibilities myself. It has started to become like the discussions of "what should we do with the schools?" or "why aren't people going to church anymore?" Anyone whoever had an education or was ever in a church thinks they are an expert with a unique perspective which they should feel free to pronounce on.
I don't mean to sound entirely negative about that. There's no obvious answer and the discussion can be interesting. Also, it's got lots of numbers and graphs. I think on all such discussions I get quickly exasperated with the people who don't bring their own numbers and graphs or worse, won't look at anyone else's because they have a Theory, dammit. We don't need no steenking graphs. We have the answers.
There have been a couple of recent additions to the discussion which have caused me to step back and think "Maybe I have been missing a basic point. Let's look at this."
Lyman Stone, whom I have have admiration for, thinks there is a huge flaw in the numbers in that the decrease in children per woman measures the number of births rather than the eventual completed family size. There is still a decrease below the level of replacement, but the overall drop is only about half as large, or even a third as large, as historical levels up until very recent times. Babies and young children died a lot before reaching an age at which they could reproduce.* I have linked to him putting forth variations of this for a couple of years now. He and others (Ruxandra Teslo, Cremieux Recueil) have thus thought that a few moderate solutions might be enough to turn the tidce, rather than trying to find the big societal makeover that is going to fix everything. Stone just updated and discussed with new numbers from Turkey, which has been a controversial discussion in the last decade.
Next, I have just read Richard Hanania taking a 30,000-ft view and wondering if there actually is a problem at all. For what human beings want out of life, not only individuals but entire societies seem to manage their fertility rates moderately well, and have throughout history. Because this is against a background of constant catastrophe, how automatically we do this has been obscured. But one of the things that humans want is some respite, some alone time. In most eras it is hard to afford even a little of it, but as prosperity has increased we can afford to have more - and maybe that's fine. I should point out that I started by liking Hanania, grew tired of him because of his reluctance to engage opposition fairly, but have come back on board a bit this year. He is quite intelligent and an original thinker. I just wish...well, never mind. that should be enough. I don't have to live with the guy after all.
*It helps to bear this in mind when we look back (or abroad) at societies where women have children at what we would consider horribly young ages. Life was uncertain for the entire tribe. Catastrophes could reduce population quickly. When a man had enough resources to support children he was expected to take a wife, or more than one. When a girl was old enough to conceive, she was expected to. The cultural excuses arrangements for that were varied, but catastrophe was the underlying problem which had to be repeatedly solved. The increased prosperity of Western Europe allowed both sexes to marry later or not at all. (See our old friend the Hajnal Line.) As the rest of the world gets prosperous, they are doing the same.
