ManuscriptUsing a multi-stage cluster sampling approach, we collected healthcare and demographic data from 531migrants and 529 local urban residents aged 16-64 in Shanghai, China. Logistic regressions were used to analyze the relationship between gender-migration status and healthcare utilization while controlling for predisposing, enabling and needs factors. Other things equal, female migrants and male locals had significantly lower actual healthcare utilization rates, compared to female locals. Female migrants were more likely to report "no money" as a reason for not seeking care, while male locals were more likely to report "self-medication" as a reason. Considering established gender differences in healthcare utilization, we conclude that female migrants as a group face the most healthcare access barriers among all groups
