Why are certain neighborhoods healthier than others?
It's a question that's received no small share of academic attention in recent years (CityLab has variously touched upon the topic here, here, and here.) With no definitive single answer, the discussion continues to expand. Is it accessibility to nutrition—living near and being able to afford Whole Foods versus 7-Eleven? Perhaps it's economic segregation, which can starve low-income minority populations "of access to key social goods, such as education, health care, adequate housing, [and] recreational amenities," according to one relevant study by the University of California, San Francisco's Center for Health and Community.
