Methodology Notes: 

    A woman was considered to have taken multivitamins/folic acid if she reported taking it every day of the week during the month before she got pregnant. Data from participating PRAMS states (28 states and New York City in 2007) were combined with data from the California's Maternal and Infant Health Assessment (MIHA) to produce the displayed estimate. The PRAMS response category was “every day” while the MIHA response category was “every day or almost every day.”

    Health Insurance status data reflect prepregnancy insurance coverage of mother.
