Preterm Births by Mother's Race/Ethnicity, New Jersey, 2000 to 2022

Indicator Report Data View Options

Why Is This Important?

Prematurity increases the risk for infant morbidity and mortality. Infants born preterm are at greater risk of dying in the first month of life. Preterm infants may require intensive care at birth and are at higher risk of developmental disabilities and chronic illnesses throughout life. They are more likely to require special education services. Health care costs and length of hospital stay are higher for preterm infants. The more preterm an infant is born, the more severe the health problems are likely to be.


Percent of live births before 37 weeks of gestation based on obstetric estimate Preterm is synonymous with premature. Infants born before 37 weeks of pregnancy are considered preterm and those born at or after 37 weeks of pregnancy are called full term. Most pregnancies last around 40 weeks.
