Public transit is indispensable for zero-vehicle households to access healthcare. Meanwhile, different households have unequal transit-based healthcare accessibility due to different socio-economic and spatial factors. Few studies have comprehensively explored the inequality in transit-based healthcare accessibility across different income, race/ethnicity groups and geographic areas. This study fills the gap with an up-to-date analysis of transit-based healthcare accessibility at the census tract level for zero-vehicle households across different income levels (i.e., low-income/non-low-income), races/ethnicities (i.e., white/black/Hispanic) and areas (i.e., central city/inner-ring/outer-ring suburb). The results show that income has a larger impact on accessibility than race/ethnicity and area of residence. White-dominated census tracts have better accessibility than minority census tracts across different areas, and census tracts in the outer-ring suburb generally have the worst accessibility regardless of race/ethnicity. This study advances understanding of transit-based healthcare access inequality across income, race/ethnicity and area and guides the allocation of resources for transit-based healthcare access improvement.
