aHealthy People 2020 objectives for breastfeeding in early postpartum period, at 6 months and 12 months are 81.9%, 60.6% and 34.1%, respectively. Healthy People 2020 objectives for exclusive breastfeeding through 3 and 6 months of age are 46.2% and 25.5%, respectively. National data on exclusive breastfeeding are not available for children born prior to 2003. See survey methodsfor details on study design.

aFormula supplementation is defined as supplementation of breast milk with formula (with or without other supplementary liquids or solids) among infants breastfed at the age specified (2 days, 3 months, or 6 months). National data on formula supplementation are not available for children born prior to 2003. ­­­See survey methodsfor details on study design.

Sample sizes appearing in the NIS breastfeeding tables are slightly smaller than the numbers published in other NIS publications due to the fact that in the DNPAO breastfeeding analyses, the sample was limited to records with valid responses to the breastfeeding questions.

Tables and Maps

Breastfeeding data shown below are stratified by sociodemographic and geographic characteristics. Provisional data for 2010 and final data for 2007 through 2009 will be added at a later time when all tables and maps in this series will be released in a new interactive format.

Note: The sample size was insufficient to present estimates by sociodemographic or geographic characteristics for the 1999 births. Similarly, data on exclusive breastfeeding and formula supplementation were available on too few of children born in 2003 to enable sociodemographic or geographic breakdowns (survey methods).
