Objective Develop and test measures of risk of deportation and mixed‐status families on women, infants, and children (WIC) uptake. Mixed‐status is a situation in which some family members are U.S. citizens and other family members are in the United States without proper authorization. Methods Estimate a series of logistic regressions to estimate WIC uptake by merging data from the Fragile Families and Child Wellbeing Survey with deportation data from U.S. Immigration Customs and Enforcement. Results The findings of this study suggest that risk of deportation is negatively associated with WIC uptake and among mixed‐status families; Mexican‐origin families are the most sensitive when it comes to deportations and program use. Conclusion Our analysis provides a typology and framework to study mixed‐status families and evaluate their usage of social services by including an innovative measure of risk of deportation.
