Methodological Notes: 

Live births with unknown birth weight are excluded.

Prior to 1993, some states did not report Hispanic origin on the birth certificate; these states are excluded from the estimates for Hispanic mothers (any race), White Non-Hispanic mothers, and Black Non-Hispanic mothers. Data for White Non-Hispanic and Black Non-Hispanic mothers prior to 1989 are not nationally representative and are provided solely for comparison with the data for Hispanic mothers.
