The true costs associated with suburban living - especially transportation costs - are bringer more people into the cities. And this youthful exodus from the suburbs is bringing a desire for transit accessibility and walkable neighborhoods.
"The U.S. is in the midst of a transit-building boom, with almost every metropolitan region planning or building some form of urban rail, busway or streetcar system. The competition for federal funding is so intense that the wait to get a proposed new project funded is almost 50 years. As a result, some regions aren’t waiting. Last fall voters in Denver, for example, approved a local sales-tax increase to fully build out their transit system in a dozen years, improving their bus system and adding six light rail lines, three commuter rail lines, and 70 stations."
