"The aim of this book is threefold. First to put in one place for the convenience of both scholars and practitioners the basic data on redistricting practices in democracies around the world. Remarkably, this data has never before been collected. Second, to provide a series of short case studies that look in more detail at particular countries with regard to the institutions and practices that have evolved for redistricting and the nature of the debates that have arisen. Third, to begin to look in comparative perspective at the consequences of alternative redistricting mechanisms and at the tradeoffs among competing redistricting criteria"--Jacket.
