The dependent variable in all models is the dietary diversity score of households, including 12 food groups. Models were estimated with a Poisson estimator. Coefficient estimates are shown with robust SEs in parentheses. The pooled data model was estimated with country fixed effects. See Table S3 for full results. *, **, *** Statistically significant at the 10%, 5%, and 1% level, respectively.
