WIC Program Participant Information​​

The WIC Program serves five categories of participants: pregnant women, breastfeeding women up to 12 months postpartum, non-breastfeeding women up to 6 months postpartum, infants, and children up to age 5. In addition to the categorical eligibility requirement, participants must be at or below 185 percent of the federal poverty level (equivalent to an annual income of $29,637 for a family size of two through June 30, 2017). Various reports and data sets are available describing program participants, outreach strategies, and redemption patterns.

 

Maternal Infant Health Assessment (MIHA) Snapshots for Prenatal WIC Participants

This report provides information on WIC maternal experiences and behaviors before, during and shortly after pregnancy based on data collected from the MIHA survey in 2013-14. Key indicators include: women’s health status, nutrition, perinatal depression, food insecurity, intimate partner violence, health insurance, infant sleep, breastfeeding and demographics. Statewide results are available for subgroups of women who participate in WIC during pregnancy based on: age, race/ethnicity, education, income, prenatal health insurance, neighborhood poverty, geographic area (urban and rural/frontier) and total live births. Statewide results are also shown by WIC status during pregnancy, categorizing women as prenatal WIC participants, eligible nonparticipants, or ineligible for WIC. County level data are available for the top 35 birthing counties; the remaining 23 counties are included in regional snapshots.

 

Innovative Strategies

In the Fiscal Year 2017, the CDPH/WIC Division funded 9 Local Agencies to identify, implement, and evaluate innovative strategies and methods that will improve the recruitment, re-engagement, and retention of eligible WIC applicants and participants.

 

Making Connections: Understanding Women’s Reasons for Not Enrolling in WIC during Pregnancy (2016)

Using 2010-2012 data from the Maternal and Infant Health Assessment (MIHA) survey, this report identifies reasons why eligible women do not enroll in WIC during pregnancy and the characteristics of women reporting each reason. Approximately 53,600 women per year were eligible for WIC but did not enroll during pregnancy. The two leading reasons statewide for not enrolling in WIC during pregnancy were not thinking they would qualify (40%) and not thinking they needed WIC (35%). The percent of women reporting each reason is also shown by race/ethnicity and other characteristics.
