Updated data on births
PeriStats has been updated with 2014 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
- Preterm Birth
- Prenatal Care
- Singletons and Multiples
- Delivery Method
This data update includes a change in the gestational age data shown on PeriStats. Beginning with the 2014 natality data, NCHS switched the primary measure of gestational age from last menstrual period (LMP) to obstetric estimate (OE). Preterm birth rates, very preterm birth rates, and other percentages of births by gestational age calculated using OE are not comparable to LMP data, and therefore PeriStats will only be showing OE data beginning with this data update. Because of this switch in measurement, the March of Dimes reset its preterm birth goal for 2020 to 8.1%. These data are presented on PeriStats for the first time. More information on the transition to OE data and trend data by state back to 2007 are available from NCHS. View our preterm birth calculations page for more information.
We are pleased to announce enhancements have been made to PeriStats to improve the user experience.
- Upgraded mapping and charting software now provides an expanded interactive experience for the user. New charts and maps allow the user to hover and view the rates and category names or geographic tags.
- A new map type has been added for preterm birth, showing each county's preterm birth rate in comparison to the March of Dimes 2020 goal of 8.1%. Counties in purple have met or exceeded the MOD 2020 goal, and red counties are those with the highest rates of preterm birth in the state.
- An updated PowerPoint slide template allows users to download charts and maps and seamlessly integrate them into their own presentations.
PeriStats Tip: Don't forget to check out the contextual statements below each map, graph or chart that explain the data in words.
