National Immunization Survey (NIS)
CDC surveys breastfeeding practices in the United States to monitor progress over time and identify priority areas that need attention. The National Immunization Survey (NIS) uses random-digit dialing to survey US households with children and teens. It provides current national, state, selected local level, and some US territory estimates of vaccination coverage rates for US children aged 19 to 35 months, teens aged 13 to 17 years, and flu vaccinations for children aged 6 months to 17 years. Since July 2001, breastfeeding questions have been asked on the NIS and are used to monitor breastfeeding rates at both national and state levels by birth year. All respondents with children aged 19 to 35 months are asked the breastfeeding questions.
