Data Source

National Immunization Survey-Child, Center for Disease Control and Prevention, 2000–2021

https://www.cdc.gov/breastfeeding/data/nis_data/results.html

NIS uses random-digit dialing to survey US households with children and teens. 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.

Notes

Breastfeeding data is reported by child's birth year rather than survey year.
