This report is a census of women, infants, and children who were participating in the WIC program in April, 2012. The report includes information on participant income and nutrition risk characteristics, and estimates breastfeeding initiation rates for WIC infants.

The WIC Participant and Program Characteristics (PC 2006) report summarizes demographic characteristics of WIC participants nationwide in April 2006, along with information on participant income and nutrition risk characteristics. A national estimate of breastfeeding initiation for WIC infants is included. The report also describes WIC members of migrant farm-worker families.

While a great deal of breastfeeding promotion and support is happening in WIC at both the state and local levels, there has been no systematic effort to evaluate what might work best in the WIC setting. Within this context, FNS  contracted for a breastfeeding intervention design study with the following goals: Identify interventions to increase the incidence, duration and intensity of breastfeeding among women participating in WIC; and design an evaluation plan to examine the implementation and effectiveness of these interventions.
