Disaggregating Race and Ethnicity: Toward a Better Understanding of the Social Impacts of Transport Decisions

By 2042, racial and ethnic subgroups are predicted to make up more than half of the U.S. population. This shift in population distribution, along with population growth and an aging population, will present new challenges for all segments of society, including transportation. This paper provides an overview of the differences in and among ethnic and racial subgroups of the U.S. population and the intersections of these with age, functionality and geography. Adverse health outcomes may be anticipated where racial and ethnic minorities experience lack of access and mobility due to geographic isolation, income, and limited mental and physical functionality. Transportation's role in increasing access and mobility may aid in offsetting or mitigating these adverse effects. Greater investments in pedestrian and bicycle facilities may aid in offsetting adverse health outcomes by providing safe places to walk and bicycle. Coordination of human service and public transportation may also serve to mitigate some of the adverse conditions by improving access to health care facilities and other activities that improve mobility.
