The impact of early death on birth counts in the United States, 1950 to 2019.

In a previous issue of , Bor et al. quantified the number of "missing Americans"-the deaths that would have been averted if the United States had experienced the mortality conditions of other wealthy nations. In 2019 alone, their estimates indicate that more than 100,000 individuals in reproductive ages (15-49 years) would have survived. The concept of the "missing Americans" is a valuable one, but here we argue that it is incomplete because it does not include children that would have been born to those who died an early death. We examine 3 indicators to assess the strength of the mortality-fertility nexus at the population level, showing that mortality more negatively affects birth counts in the United States than in other wealthy nations. Using the mortality conditions in other wealthy nations as a reference, we estimate that between 2010 and 2019 alone, approximately 200,000 children were not born in the United States due to the premature death of their potential mothers. Our findings highlight that improving morbidity and mortality among people of reproductive age-without compromising their reproductive autonomy-is critical in the United States.
