QuickStats: Percentage of Infants Born Late Preterm,* by Mother's State of Residence — National Vital Statistics System, United States, 2012
* Defined as a gestational age (interval between the date of the mother's last normal menses and the date of birth) of 34–36 completed weeks. Late preterm births accounted for 70% of all preterm births in 2012 and are considered to be at less risk than births at <34 weeks (early preterm) but at greater risk for birth complications and subsequent health or medical problems than full-term births.
In 2012, 8.1% of births in the United States were late preterm births. The percentage of births that were late preterm varied by state and ranged from 6.2% in Vermont to 12.0% in Mississippi.
