Impact of County and State Immigration Policies on Immigrant Household Enrollment in the Supplemental Nutrition Assistance Program

Introduction Low-income immigrants who are eligible to participate in the Supplemental Nutrition Assistance Program (SNAP) participate at lower rates compared to non-immigrants. Immigrant households may be more likely to participate in SNAP if they live in areas with policies that integrate them into society and protect them from deportation. Methods Data on low-income immigrant households came from the 2019 American Community Survey (N=87,678). The outcome was whether any household member received SNAP in the previous 12 months. Immigrant policy exposures came from two sources: the State Immigration Policy Resource, which includes 18 immigrant criminalizing and integrating policies, and a database that identified ‘sanctuary policies’ (SP), which we summarized at the county level. Multivariable logistic regression adjusted for person/household-level and area-level confounders. Results Living in a jurisdiction with a SP was associated with 21% higher odds of enrolling in SNAP compared to living in a jurisdiction without a SP (adjusted odds ratio [aOR] 1.21, 95% CI=1.11,1.31). Relative to the least immigrant friendly states, living in the most immigrant-friendly states was associated with 16% higher odds of SNAP enrollment (aOR=1.16, 95%CI=1.06-1.28). When SP and state-level immigrant friendly policy environment were cross-classified, SNAP participation was 23% and 26% higher for those living in jurisdictions with one- and both- exposures, respectively, relative to those with neither (aOR 1.23; CI 1.12,1.36; aOR 1.26; CI 1.15,1.37). Conclusions Many at high risk of food insecurity – including immigrants and citizens in households with immigrants – are eligible for SNAP but under-enroll. Policies that welcome and safeguard immigrants could reduce under enrollment.
