Another example of the “poverty kills” principle: in low-income neighborhoods in NYC, children face a higher risk from traffic. The same is probably true in any other city, but I only have data for NYC:
Intersections near public housing appear to be particularly dangerous for children trying to cross the street. That is the case even after correction for a neighborhood’s population size. The design of roads, intersections and public housing complexes is probably one of the major causes of this, together with the fact that poor people and poor children in particular are more likely to use the roads as pedestrians (they have less entertainment alternatives and make less use of cars).
