There is a demographic inversion taking place in America, according to Alan Ehrenhalt. Alan is executive editor of Governing Magazine, and in an article last month for The New Republic, he contends that we are beginning to see a new trend in America where people with financial options about where they live are moving to cities, while those with less money are moving to the edges of metro areas.

Also, author, activist and community organizer Harry Boyte talks about his new book, The Citizen Solution, which describes the many ways Americans are now asserting themselves as citizens to shape their communities.

Smart City is a syndicated, weekly hour-long public radio talk show that takes an in-depth look at urban life: the people, places, ideas and trends that affect us all. Host Carol Coletta, president and CEO of CEOs for Cities, talks with national and international public policy experts, economists, business leaders, artists, developers, planners and others on the pulse of city life for a penetrating discussion on urban issues.

Smart City is broadcast at 6 a.m. Saturday and Sundays on WKNO-FM, but it is also webcast and podcast so you can listen to it anytime you like. For the webcast, times for the broadcast in other cities and to sign up for the podcast, visit our website.
