Response to how common are twins

 

Here's a quote from Wikipedia: "North American dizygotic (frats) twinning occurs about once in 83 conceptions." But they don't seem to have figures for monozygotic. Another site gives this for identicals: "3.5 per 1000 ( 1 in 285) (this figure seems to be universal and random)" Of course, many of the fraternal twins you see today are the result of fertility drugs and IVF. Also, some of the identicals may come from fertility treatment, because there seems to be a greater tendency of embryos to split than in natural conception. And older mothers are also more likely to be twin moms.

But in our area, the D.C. area, where women have deferred childbearing and the population is affluent and can afford fertility treatment, there are piles of twins. I was in the Costco when the twins were babies, and this woman comes over and says, "Oooohhhh, are they twins?" And I replied that they were. And she said, "They're the third pair I've seen in here today!" OK. You're in my face going gaga over my twins, and you've already seen two other sets in the store just today?

Take care,
