What you're missing is the distinction of how old women are when they have their *first* child. As a rule, carrying to term again after successfully having done it at least once tends to be become easier each time until you start getting close to menopause. It's a curve with a finite end point, and the older you are when you carry your first child, the more difficult it is to stay on the curve.This may be a dumb question but I thought I read that the trend of society is that women are having babies at a later age (30+) than a younger one (20+). So is it just becoming more common that women are having babies in their 40’s due to culture/medical advancements?
Maternal age at first birth has indeed been consistently rising over time, but for women who already had done it at least once, giving birth again after age 40 was completely normal up until the mid 1960s, when oral birth control pills became widely available to married women, at least in the US. Before reliable hormonal birth control, the majority of hetero women who had regular relations gave birth the first time within 2 years of getting married, and commonly did it again roughly every 2-3 years after that until menopause sometime close to age 50 or so. Absent the use of birth control, that's still the case. What has changed is that we commonly use hormonal birth control to delay first pregnancies until much later, and use it again to limit family size.
