Public Health in the Political Sphere: Zero-Fare Public Transportation as a Case Study and Call to Action

Calls for depoliticizing public health often conflate politicization with partisanship, limiting the tools we have to advance health equity. We argue, through the lens of zero-fare public transit, that promoting health equity is an inherently political process. The processes that advance access to public services as a public good exist in the political sphere and have direct impacts on the health of vulnerable populations. To advance population health goals regarding the social determinants of health, engagement in the political sphere is necessary. We provide recommendations for the path forward regarding research, advocacy, and training to advance our field.
