Abstract
How do traditional redistricting principles—contiguity, communities of interest, political subdivisions, incumbent protection, Section 5 of the Voting Rights Act, preservation of district core, and compactness—affect racial minority representation in congressional districts? Using data from the 2001–02 redistricting process, we find that compactness is the only principle that significantly affects minority representation, both in terms of majority-minority districts and minority influence districts, but these effects are contingent on the size of the minority community and extent of racial segregation in a state. Two other principles, Section 5 pre-clearance and protecting political subdivisions, improve minority representation in a more limited way. Thus, race-neutral redistricting criteria like the compactness principle, can dramatically affect the racial composition of the resulting districts and, thereby, affect minority representation.
