Breastfeeding Report Card
National and state-by-state information on breastfeeding rates and breastfeeding support indicators.

Breastfeeding Rates
The National Immunization Survey (NIS) provides information on the number of children who breastfeed each year, by state. Although NIS data are used to study vaccination rates, beginning in 2001, breastfeeding questions were added and are used to track breastfeeding practices in the United States.

Data, Trends, and Maps is an interactive tool that provides the most recent information on obesity, nutrition, physical activity, and breastfeeding nationally and in states and territories across the United States.

Hospital Practices
The national Maternity Practices in Infant Nutrition and Care (mPINC) Survey provides information that helps hospitals make it easier for moms and babies to start and keep breastfeeding. Every 2 years, CDC invites all maternity care hospitals across the country to fill out the mPINC Survey. The questions focus on specific parts of hospital maternity care that affect how babies are fed.

Public Opinions about Breastfeeding
SummerStyles provides information on health-related opinions of people aged 18 years or older, across the United States. Since 1999, breastfeeding questions have been included to collect information on public beliefs and attitudes about breastfeeding.

Breastfeeding and Infant Feeding Practices
The Infant Feeding Practices Study II (IFPS II) provides information on infant feeding patterns (e.g., breastfeeding, formula feeding, complementary feeding) in the United States throughout the first year of life, as well as information on the diets of women in their 3^rd trimester and at 4 months postpartum. The corresponding 6-year follow-up (Y6FU) study provides information on the health, development, and dietary patterns of these children at 6 years of age.
