US public opinion about interior border checkpoints and health care access for undocumented immigrants

Abstract Legal status is an important social determinant of health. Immigration enforcement policies may be an important contributor to health disparities in the form of interior border checkpoints (IBCs). These checkpoints may prevent immigrants and their families from seeking needed medical care. Currently, we do not know how these barriers are perceived by the public. We administered a survey of 6,178 respondents from 13 November to 19 November of 2023 that contained a survey experiment to assess public attitudes on the issue. Respondents were generally not supportive of detaining individuals at IBCs or medical facilities for emergencies regardless of characteristics of the care-seeking individual. A majority was supportive of detention when medical treatment was complete. Respondents were generally more sympathetic towards children and pregnant women. Partisanship and sympathy expressed towards immigrants influenced attitudes towards detention. Findings based on race and ethnicity showed inconsistencies. A majority of Americans did not believe that IBCs should impede undocumented immigrants from accessing medical care, especially in emergency situations and for children and pregnant women. Our findings indicate that there is broad public support for expanding existing policies to allow for undocumented individuals to pass through IBCs to access medical care.
