In a chapter of the Meaning of Marriage, Roger Scruton claims that the move away from marriage reduces fertility below replacement level. Using GSS data since 2000, I calculated the mean number of offspring for white women ages 40-59 by marital status. If Scruton is right, married women will have the most kids, never-married will have the least, and separated/divorced women should be in the middle. Let's look at less and more educated women separately:
Mean number of offspring
Women with less than four-year degree (sample size = 1,759)
Women with four-year degree or more (sample size = 866)
*significantly lower than corresponding married or separated/divorced groups
Never-married women have fewer kids than married or separated/divorced women whether they are more or less educated. Educated single women have hardly any children at all. A society made up of these type of women would pretty much disappear in a historically short period of time. Next, I'll look at black women.
