Using data spanning 1996–2009 from multiple panels of the Survey of Income and Program Participation, this study investigates children’s (average age 8.5 years) physical health, dental visits, and doctor contact among low-income children (= 46,148) in immigrant versus native households. Immigrant households are further distinguished by household citizenship and immigration status. The findings show that children residing in households with non-naturalized citizen parents, particularly those with a nonpermanent resident parent, experience worse health and less access to care even when controlling for important demographic, socioeconomic, and health insurance variables.
