A Phoenix NPR station, KJZZ, has an interesting conversation with Armando Carbonell of the Lincoln Institute’s Department of Planning and Urban Form. The questions revolve around how American cities are attracting – or repelling – the next generation. It includes some interesting discussion about how housing costs and cultural perceptions may be affecting migration trends; why Austin and Portland are unique among non-major cities; and how the expense and commercialization of New York City and San Francisco are apparently driving young people to more affordable regions.
