Declining Fertility Rates and Age of First Birth

Fertility rates in the United States have seen a significant decline, dropping from approximately 71 births per 1,000 women in 1990 to 56 in 2022. The age at which women have their first child has also increased, with the average age rising from 27 in 1990 to 30 in 2019. Contributing factors to this trend include economic concerns, work commitments, and insufficient support systems for pregnancy and child-rearing. As women opt to postpone childbearing, understanding the implications of ovarian aging on fertility becomes vital to address these societal shifts.
