Starting with 2009 births, rates are based on a dual-frame sample that includes respondents surveyed on landline or cellular telephones. See survey methods for details on study design and the impact of adding a sample of cellular telephone respondents to the National Immunization Surveys starting in 2011.

bHealthy 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 methods  for details.
