Quick Facts: Perinatal Overview

PeriStats compiles maternal and infant health data from multiple sources. These data are often referred to as perinatal data. The term "perinatal" can be used in a generic or a very specific way. It means around (peri-) the time of birth (-natal), so it can be used to refer to the entire or parts of the period around conception and through the first year of life.
