About The Study: In this population-based cross-sectional study, infant mortality risk was inversely associated with county-level access to maternity care, with the highest risk in counties with no access. When examined by race and ethnicity, differences in mortality risk between living in a full access and no access county were observed among white infants only, indicating that unmeasured barriers may limit the protective effect of access for some racial and ethnic groups.
