Preterm birth is a worldwide epidemic with a global incidence of 15 million per year. Though
rates of preterm birth in the United States have declined over the last decade, nearly 1 in 10
babies is still born preterm. The incidence, gestational age, and underlying etiology of
preterm birth is highly variable across different racial and ethnic groups and geographic
boundaries. In this article, we review the epidemiology of preterm birth in the United States
and globally, with a focus on temporal trends and racial, ethnic, and geographic disparities.
