* Based on National Immunization Survey-Child data from survey years 2016–2017, among infants born in 2015.
† Statistics in this table are based on participants who responded to questions about any breastfeeding at ages 3 and 6 months (N = 11,514). Sample sizes are slightly smaller for participants who also responded to questions about exclusive breastfeeding at ages 3 and 6 months.
§ Ratio of self-reported family income to the poverty threshold value defined by the U.S. Census Bureau.
¶ Sample sizes for the proportions of participants receiving WIC are slightly smaller due to missing data on WIC status.
