A new study confirms what you already know: Jamaica Plain is full of creative types. Demographer Richard Florida argues this "creative class" represents a new kind of class divide. Florida, director of the Martin Prosperity Institute and one of the study’s authors, says that class is an inescapable presence in America. And he makes a point that class is embedded in our geography; there’s a clear relationship. “The Divided City: And the Shape of the New Metropolis” intends to help people better understand the relationship between class and geography since it’s an inevitable factor in our way of life, according to the study.
