Despite the fact that how electoral boundaries are drawn can fundamentally affect the nature of political representation—who gets what, when—remarkably little has been written on the subject of redistricting practices apart from the large US-specific literature dealing primarily with jurisprudential issues. In particular, with the notable exceptions of a few encyclopedic books such as that by John Courtney on Canada and D. J. Rossiter, R. J. Johnson and C. J. Pattie on the UK, there are few country- specific studies of redistricting apart from the United States. When it comes to comparative work the picture is even bleaker. While there are a number of purely mathematical and statistical essays (such as the excellent cross-national analysis of levels of malapportionment by Samuels and Snyder), there is very little in the way of studies that offer multicountry comparisons of redistricting practices and principles. Thus, we believe this set of essays, all of which are works specifically commissioned for this volume, fill an important niche. Almost all of the essays in this book were initially presented at a conference entitled “Redistricting in Comparative Perspective,” held at the University of Cal- ifornia, Irvine, December 7–9, 2001. We would like to acknowledge the invaluable help of Clover Behrend-Gethard and of the accounting staff of the School of Social Sciences in handling conference logistics. Versions of two of the papers presented at the conference subsequently appeared in journals: “United States Redistricting: A Comparative Look at the 50 States,” by Michael McDonald, was published in State Politics and Policy Quarterly (4(4) 2004: 371–96) as “A Comparative Analysis of U.S. State Redis- tricting Institutions”; and “Reserved Seats in National Legislatures: A Compara- tive Approach,” by Andrew Reynolds, appeared in Legislative Studies Quarterly (30(2): 2005: 301–10) as “Reserved Seats in National Legislatures: A Research Note.” We offer updated iterations of the original conference papers and the published articles in this volume. Excerpts from the two published articles are reprinted with the permission of the authors. In addition, earlier versions of the two papers written by Lisa Handley were prepared for the Center for Transitional and Post-Conflict Governance, at IFES, under the direction of Jeff Fischer. The comparative redistricting conference was funded by the National Science Foundation and the Center for the Study of Democracy at the University of California, Irvine, with supplementary funding from the UCI Academic Senate Committee on Research. This book is part of a broader study of “Representation, Electoral Rules, and Civic Inclusion” that is one of the signature projects of vi Acknowledgments the Center for the Study of Democracy at the University of California, Irvine (http://www.democ.uci.edu). This will be the sixth book in a series on this topic, all resulting from conferences at UCI held over the past 15 years. The five previous books in the series are Bernard Grofman (ed.), Legislative Term Limits: Public Choice Perspectives, Boston, MA: Kluwer, 1996; Bernard Grofman, Sung-Chull Lee, Edwin Winckler, and Brian Woodall (eds.), Elections in Japan, Korea and Taiwan under the Single Non-Transferable Vote: The Comparative Study of an Embedded Institution, Ann Arbor, MI: University of Michigan Press, 1999; Shaun Bowler and Bernard Grofman (eds.), Elections in Australia, Ireland and Malta under the Single Transferable Vote, Ann Arbor, MI: University of Michigan Press, 2000; Matthew Shugart and Martin Wattenberg (eds.), Mixed Member Electoral Systems: The Best of Both Worlds, Oxford: Oxford University Press, 2001; and Bernard Grofman and Arend Lijphart (eds.), The Evolution of Electoral and Party Systems in the Nordic Countries, New York: Agathon Press, 2002. This volume also reflects a natural continuation of previous work of the editors on represen- tation, redistricting, and comparative electoral systems, for example, Bernard Grofman, Lisa Handley, and Richard Niemi (eds.), Minority Representation and the Quest for Voting Equality, Cambridge University Press, 1992; Bernard Grof- man (ed.), Political Gerrymandering, Agathon, 1990; and Bernard Grofman (ed.), Race and Redistricting, Agathon, 1998.
