Why Is This Important?
Nonmarital births are at higher risk of having adverse birth outcomes such as low birthweight, preterm birth, and infant mortality than are children born to married women.1 Children born to single mothers typically have more limited social and financial resources.2
Definition
Marital status was determined by response to the following questions on the birth certificate:
- For years 1970-1978 - Legitimate?
- For years 1979-1988 - Is mother married?
- For years after 1988 - Mother married? (At birth, conception, or any time between)
