Data Topics

Use this page to browse the multiple different data sets and indicators that PeriStats offers on maternal and infant health subjects. The data search tool on this page will guide you through the data we continually update.

Preterm Birth

Preterm birth is defined as a live birth before 37 completed weeks gestation. Some other classifications of preterm births include late preterm (34-36 weeks), moderately preterm (32-36 weeks) and very preterm (<32 weeks). These classifications are useful because they often correspond to clinical characteristics - increasing morbidities or illnesses with decreasing gestational age. Babies born too soon are often born too small. While the causes of preterm birth and low birthweight may be different in some cases, there is significant overlap within these populations of infants.
