Data – PRAMS



PRAMS survey responses supplements data from birth certificates for planning and assessing maternal and child health programs on a state level. Because PRAMS data are population–based, findings from data analyses can be generalized to the entire state´s population of women having live births. Health planners have used PRAMS data to help understand maternal behaviors and experiences and their relationship to pregnancy outcomes.

MN PRAMS Methodology

Minnesota uses the standardized data collection methods developed by CDC. The CDC´s methodology is used by all states participating in PRAMS.

  1. A sample of approximately 200 mothers is selected monthly from Minnesota birth certificates.
  2. At two to six months after delivery, each mother is mailed an introductory letter followed by the Minnesota PRAMS Questionnaire Phase 7 (PDF)
  3. For those who do not respond to this questionnaire, Minnesota PRAMS sends a reminder letter, and the questionnaire out a second and a third time.
  4. Telephone interviewers for Minnesota PRAMS call mothers who do not respond to the mailed questionnaires. The questionnaire is administered by telephone in English or in Spanish.


Minnesota PRAMS statistics are based on weighted data. The weights are adjusted to account for sample design, nonresponse patterns and omissions from the sampling frame. Weighting is necessary to give unbiased estimates. PRAMS data are representative of Minnesota resident women, age 14 and older, who have had a live birth in Minnesota.


PRAMS data are essential to implementing Minnesota´s goal of eliminating health disparities. In Minnesota, African American (U.S.–born) and American Indian mothers have poorer birth outcomes than other mothers. Therefore, African American and American Indian mothers are oversampled in order to obtain estimates that are more precise for these maternal populations.

Strengths of PRAMS data

  • Robustness of standardized data collection methodology for comparisons within states and among states

  • Uniqueness of PRAMS questionnaire which provides data that are not available from other sources about pregnancy and the first few months after birth
