The Kids Are All Right: Follow-up

My post on the relationship between ideology and fertility rates generated some great feedback and critiques (albeit mostly on a Facebook thread). Sadly, none of this was related to the awesome pun in the title of the piece. (Seriously, no love for “The Kids Are All Right”?)

Well, life goes on.

In light of the interest in the subject, I’ve decided to do a quick follow-up piece to address some readers’ questions and adding a bit of information, particularly as relates to this graph from the original post:

Conservative have more kids

1. Are there more people on the political left?

A couple people asked about the ideological composition of the nation and the sample I used. This is an important question, because if the political right makes up a small enough minority of the population or sample, then my graph, which shows the average number of children per respondents of different ideologies but doesn’t convey sample sizes, is a bit misleading—or at least less compelling. So my fault for not going into it in the first place.

Per the most recent polling by Gallup, The American electorate identifies as roughly 26% liberal, 35% moderate, and 35% conservative. This is after two decades of a slow, steady increase in the percentage of Americans calling themselves “liberal.” More on that later.

The sample I pulled from the General Social Survey (GSS) reflects Gallup’s national numbers pretty well: out of the total 8,539 respondents sampled, 2,346 (27.47%) identified as some degree of liberal, 3,285 (38.47%) as moderate, and 2,908 (34.50%) as some degree of conservative.

2. Are there more women on the political left?

I believe this question is getting at the same idea: if the majority of women are left of moderate, then the higher fertility of women on the right is less consequential for the electorate. According to Gallup’s national numbers, 30% of women identify as liberals—the same percentage as call themselves conservatives. For men, those numbers are notably different: 40% and 21%, respectively.

The sample I used showed more gender parity in ideologies, but it’s not hugely off. At any rate, the important thing is that the elevated fertility rates of conservative women can’t be written off as the effect of a small sample size.

3. But the population has been getting more liberal. Doesn’t that kind of throw a wrench in this narrative?

Only time will tell, I suppose! To be clear, this is how many people read the tea leaves, and the story I’m telling is a bit of heterodoxy. While I can’t offer a firm answer to this question now, I have a few remarks:

  • The past is no guarantee of the future. (Ask GE shareholders, amirite?) Just because the electorate has been getting more liberal doesn’t mean it will continue to.
  • I suspect the secular trend toward liberalization is as influenced by macroeconomics and sociological factors as it is individual characteristics and experiences. The question is, what will be the effects of today’s macroeconomic and sociological upheaval on future voters—or their children?
  • Relatedly, I think time horizon matters a great deal when evaluating whether or not the future looks liberal or conservative. This is theory on my part, but maybe populations naturally move to the right over the long term (because conservatives reproduce more) unless cultural forces pulling leftward—economic globalization?—are sufficiently strong and sustained.
  • Finally, I think it’s worth noting that America’s liberal ranks are mostly swelling at the expense of its moderate contingent, perhaps due to increasing political polarization.

There were a few questions brought up to which I don’t have good answers at the moment. Without promising when, if at all, to address them—I’ve learned not to make firm commitments relating to this fine blog—here are two excellent threads I should follow:

  • Does completing various life milestones (having children, buying a house, getting married) make people more conservative? There must be some longitudinal studies on this somewhere…
  • To what extent do children’s political views match their parents’, and is there symmetry between liberals and conservatives in this regard? (I linked to one study by Gallup in the last post that suggested a 70% match between parents and their children, but there’s probably a lot more work on this out there.)
