Chapters 2 through 5 cover the major factors involved in drawing the new maps. These are arranged in the order of their legal prominence beginning with the need for equal populations before moving to the obligation to avoid discriminating against minorities. Chapter 4 examines the other elements weighed by those redrawing districts: compactness, respect for political boundaries and communities of interest. Chapter 5 deals with partisan considerations and consequences of redistricting.
The seventh chapter provides a preview of the post-2010 redistricting with a discussion of projections of likely congressional reapportionment. The final chapter also considers how the changes in the Voting Rights Act adopted in 2006 may affect the next round of redistricting.
