2015 Natality Data Update

Updated data on births

PeriStats has been updated with 2015 natality data from the National Center for Health Statistic (NCHS), as compiled from birth certificate data provided by the 57 vital statistics jurisdictions through the Vital Statistics Cooperative Program.

The topics updated include

      • Births
      • Preterm Birth
      • Singletons and Multiples

These topics are available for all geographic areas and by maternal age, race, and race/ethnicity.

Also available are state preterm birth rates calculated using gestational age based on obstetric estimate (OE) for 2007-13 which were not previously available on PeriStats. More information on the transition to OE data from LMP-based gestational age are available from NCHS. View our preterm birth calculations page for more information.

Topics covering birthweight, prenatal care, and delivery method will be updated in early 2018.

PeriStats Tip: Don?t forget to check out the contextual statements below each map, graph or chart that explain the data in words.
