Apgar scores of 10 were once common but are now rare. We aggregated scores from US term infants from 1978 to 2021. We found that scores of 10 decreased by logarithmic decay independent of demographic changes. We hypothesize that this trend was driven by improved appreciation of transitional physiology.
