How old is too old? Age and the sociology of fertility.

Are we due for a new baby boom as couples who had postponed childbearing begin to make up for lost time? Analysis of National Fertility Study data suggest that "later means fewer"--quite apart from the declining fecundity that occurs at older ages. Couples who delay having children until relatively late in life are subject to fewer pressures to have children (or more children) even as the reasons not to begin (or increase) their families become more salient.
