Manypeoplehavehelped make this book possible. I especially want to thank George J. and KathleenWatersMatthews, whose support for scholarship at Northeastern University has made this book possible. I also want to thank my dean, Emily Spieler, for gener- ous research support and a schedule conducive to writing. Many thanks are also owed to my wonderful colleagues at Northeastern University School of Law. In particular, I am grateful to Roger Abrams for insisting that I finally write the book, to Hope Lewis for showing me the connections between population-based legal analysis and human rights, and to Mary O’Connell for always providing encouragement and an open R M E T Georgetown University.
