What's Behind Declining Birth Rates in the U.S.?

Author

Abstract

Using the National Survey of Family Growth, this paper explores reasons behind the falling birth rate in the United States. The analysis confirms that newer generations of women are less likely to have any children than generations that came before. Comparing outcomes among women at the same age, two sources for this decline are identified: (1) a dramatic decrease in the desire to have children, but only among the youngest generation in the sample (Gen Z) and (2) an increase in the medical difficulty of having children among all generations of women since the Boomer generation. Various policies addressing both desire and difficulties are discussed in the context of a goal to arrest or reverse declining birth rates. The primary contribution of this paper is consideration of increasing medical difficulty in conceiving and bearing children (impaired fecundity) alongside the current dominant theory of shifting priorities and preferences of recent cohorts of women.
