Pregnancy Risk Assessment Monitoring System (PRAMS)

The Pregnancy Risk Assessment Monitoring System (PRAMS) from the Centers for Disease Control and Prevention (CDC) and state health departments, collects state-specific, population-based data to monitor maternal and child health indicators. Each state samples women who have recently had a live birth by drawing from the birth certificate file. Data are weighted in order to provide representative estimates of a state?s population. Because the data are based on a weighted sample, PeriStats also displays 95% confidence intervals, provided by the CDC, to assist with interpretation of rates and comparisons (see also FAQ on confidence intervals).
