The numbers are, of course, higher still for the college-educated and 75k+.
“About four-in-ten (43%) of those with a bachelor’s degree have had some exposure to fertility treatment – either through their own experience or that of someone they know – and the share rises to 56% among those with a postgraduate degree. About half (48%) of people with family incomes of $75,000 or more also have been exposed to fertility treatment.”
This is kind of scary because it suggests that almost all fertility boost that isn’t from immigrants moving and having an initial baby boom is from artificial hormone cocktails. Or, alternatively, that vast numbers of women are subfertile or infertile. The link only covers IVF specifically, but it does note that the actual survey didn’t specify, and there’s a long list of non-IVF hormone cocktails out there.
