The choice of where to live involves many factors: price; amenities, including available transportation services; character of the neighborhood; proximity to job opportunities; and access to essential services. This choice also impacts one’s health, as phrased in the question, “When it comes to disease and health, which is more powerful—ZIP code or genetic code?”
In making a decision where to live, most people balance these factors. For example, those who wish to live in dense, urban areas, where multiple public transportation options are available (e.g., transit, bikeshare, ridehailing services, e-scooters), usually pay a higher price for their home. Those who wish to live surrounded by more green space and less density, can pay a lesser price for their home but end up paying more for transportation. CNT (formerly the Center for Neighborhood Technology developed its Housing and Transportation Calculator to help individual balance the sometimes competing interests between housing and transportation.
Urban dwellers are also more likely to be able to have access to newer transportation options, as these are designed to work best when offered in densely populated areas. Ridehailing, car sharing, bike sharing, electric scooters, and other new modes are rolled out first in urban areas, and often in areas where income levels are higher. Residents in lower income areas may not have the expendable funds to take advantage of these; residents in suburban and rural areas may find these services further and far between. In non-urban areas, any service that is priced by the mile and/or time will be more expensive as the distances to travel are greater.
