ABSTRACT
This chapter summarizes the arguments for and against neighborhoodlevel or place diversity. While this book is based on the view that neighborhood-level social diversity is essential, an understanding of the counter-arguments is necessary. I first summarize the arguments used to support place diversity as a normative goal, organized under two main headings: place vitality and social equity. The categories are interrelated, but nevertheless can be discussed as distinct concepts used to justify not only the need for place diversity, but also the need for a physical environment that can support it.
