The L.A. County WIC Data Mining Research Partnership was established in 2002 to leverage the existing WIC infrastructure of the seven local WIC agencies, providing an annual portrait of important sociodemographic and health information on all children served by WIC in LA County. The annual administrative data captured through WIC services from 2002-2018 is supplemented with triennial surveys of ~5000 WIC families (2005, 2008, 2011, 2014, 2017, 2020), which has enhanced the breadth of data available on families served by WIC.
WIC Administrative Data
All WIC programs collect extensive sociodemographic and health information about participating families. In California, all data are captured in an administrative database called WIC WISE, which is managed by the California Department of Public Health (CDPH) WIC Program. In 2002, First 5 LA funded PHFE WIC to address the critical gap in information about low-income families in LAC. Through data sharing agreements between CDPH and the seven local agencies WIC programs in L.A. County, a system was created to electronically aggregate WIC administrative data from across the county and provide an annual download of these data.
LA WIC Survey Data
The Los Angeles County WIC Survey started in 2005 and is scheduled every three years (2005, 2008, 2011, 2014, 2017, 2020). The telephone survey of WIC-participating families provides in-depth information about the health of women and children, parenting practices, early care and education, and home and community environments. The survey is conducted with a randomly-selected sample of approximately 5,000 families that reside in Los Angeles County. All interviews have been primarily conducted in English or Spanish by trained interviewers however an oversample of Vietnamese and Mandarin speaking participants was collected in 2011.
