About Us

PeriStats™ is the online source for perinatal statistics developed by the March of Dimes Perinatal Data Center. PeriStats provides free access to maternal and infant health-related data at the U.S., state, county, and city level. It was developed to ensure that health professionals, researchers, medical librarians, policy-makers, students, and the media have easy access to this information. Data are updated throughout the year, and useful for multiple tasks, including fact-finding, health assessments, grant writing, policy development, lectures and presentations.

Aggregating data from government organizations, PeriStats provides access to the most current maternal and infant health statistics on topics such as preterm birth, infant mortality, tobacco use, Cesarean birth rates, and health insurance coverage. Detailed information by race, ethnicity, and maternal age for many indicators is also available. To communicate this information, PeriStats produces sharable graphs, maps, and tables that can be utilized in various reports and presentations. The site also provides functionality enabling you to make comparisons between states, counties, and cities and to the United States. Over 60,000 graphs, maps and tables are available on PeriStats, and data are always referenced to the relevant source and Healthy People 2030 objective.
