Data & Research

The goal of this study was to pilot creating a WIC participant characteristics (PC) longitudinal data set with one WIC state agency. Eight state agencies with varying management information systems (MIS) platforms and high quality WIC PC 2020 data completed a survey about their MIS and longitudinal data provision capabilities. The survey assessed these state agencies’ MIS capabilities, as measured in six areas, to provide a longitudinal data set. This report describes the process of working with one WIC state agency to create a pilot WIC PC longitudinal data set of infant and child participants and the challenges and successes of this effort.

Since 1992, FNS has produced biennial reports on WIC participant and program characteristics based on the WIC Minimum Data Set compiled from state management information systems. The 20 items included in the MDS are collected as part of ongoing WIC operations and consist primarily of in formation related to participant eligibility.

This report (1) identifies the number and nature of recent studies that have examined the effectiveness of three WIC services—nutrition education, breastfeeding promotion and support, and referral services—and (2) summarizes what the research shows about the effectiveness of these specific nutrition services. 

This report responds to a Congressional mandate for the Food and Nutrition Service (FNS) to establish a long-range plan for the development and implementation of state agency Information Systems (IS) in the WIC program. In the development of this plan, FNS reviewed state agency system capabilities and consulted with the National WIC Association as well as systems experts. The WIC 5-Year Technology Plan included in this Report to Congress outlines the Agency’s goals, objectives, and strategies to address the current and future needs of WIC systems.
