Notes: Results are from probit regression models controlling for SNAP benefit amount, race/ethnicity, sex, age, household size, and year of ER visit. Average marginal effects with standard errors in parentheses and p-values in brackets. Standard errors clustered at the individual level. We ran a test to compare the statistical difference of the reported effects and compared column (1) with column (2). We did not find any statistical significance difference
