The Human City

Kathryn Ryan talks to Joel Kotkin, an expert in urban studies at Chapman University in Orange, California. His latest book The Human City challenges what he calls a "cult of densification" in modern thinking about cities. Joel argues that while many urban thinkers like to promote denser cities as cheaper, more environmentally sustainable and culturally rich there's plenty of evidence to the contrary - and perhaps more importantly, he says there's very little evidence people actually want to live in denser cities.
