Why is childlessness rising as a generation ages?
Core argument: Childlessness among women in their early 20s rose sharply beginning around 2002, when the first millennials, born in 1981, entered that age group, with a similar jump for women in their later 20s in 2006.
Women in their early 20s embraced childlessness first, with a sharp rise beginning around 2002. That happens to be when the first millennials, born in 1981, entered that age group. For women in their later 20s, the jump in childlessness happened in 2006, just as the first millennials arrived. As you ascend the age spectrum, the millennial echo follows. When the oldest millennials hit their 40s, even 40-year-olds become more likely to go childless. Just about every source we consulted pointed to the broader economic climate. If women are able to follow through on their delayed family plans, much of the rise in childlessness could be erased, but with older millennials in their 40s, time for a reversal may be running out.
