Data and Statistics

At a glance

CDC’s Division of Reproductive Health (DRH) monitors maternal and infant mortality, the most serious reproductive health complications. In addition, we focus on gathering data to better understand the extent of maternal and infant morbidity, and behaviors and conditions that can affect reproductive health.


Public health surveillance is the ongoing systematic collection, analysis, and interpretation of data. The public health approach includes using surveillance data to identify problems and assess the effectiveness of interventions. Without accurate and timely data, public health cannot take timely action. This glossary is available of commonly used terms in public health surveillance and epidemiology.

The major surveillance systems in DRH include the Pregnancy Risk Assessment Monitoring System (PRAMS), the National ART Surveillance System (NASS), and the Pregnancy Mortality Surveillance System (PMSS). CDC also supports the Maternal Mortality Review Information Application (MMRIA, or "Maria"), a data system designed to facilitate MMRC functions through a common data language, and the Sudden Unexpected Infant Death (SUID) Case Registry, which seeks to improve population-based SUID surveillance in jurisdictions. Reports are generated from these systems on a routine basis. DRH also monitors teen pregnancy and the number and characteristics of women obtaining legal induced abortions in the United States. Point-in-time surveys are conducted to assess reproductive health in developing countries.

CDC began abortion surveillance in 1969 to document the number and characteristics of women obtaining legal induced abortions. Many states and jurisdictions conduct abortion surveillance. This information is voluntarily reported to CDC. CDC’s surveillance system compiles the information from states and jurisdictions on legal induced abortions.

Assisted Reproductive Technology Success Rates

Fertility clinics in the United States report and verify data on the assisted reproductive technology (ART) cycles started and carried out in their clinics, and the outcomes of these cycles, during each calendar year. ART includes all fertility treatments in which either eggs or embryos are handled. The main type of ART is in vitro fertilization (IVF). IVF involves extracting a woman's eggs, fertilizing the eggs in the laboratory, and then transferring the resulting embryos into the woman's uterus through the cervix. These ART data are a rich source of information that can give potential ART users an idea of their average chances of success per ART cycle or ART transfer.
