Gentrification, Displacement, Social Mobility

Professor Lance Freeman Professor Raj Chetty

Gentrification and Displacement are real concerns. As are the effects of underdevelopment on lower-income residents in inner cities.In many cases opponents of development projects misunderstand gentrification and displacement and misstate the evidence to support their opposition. Likewise there is a misunderstanding about the positive impacts of development in these communities.

Professor Lance Freeman, who was a city planner at NYCHA and a local who literally wrote the book about gentrification in Harlem, is now a nationally recognized expert on these matters. Professor Raj Chetty likewise has completed extensive studies on mobility and displacement in neighborhood like Harlem.
