Redistricting

Known as redistricting in the United States and redistribution in many Commonwealth countries, it is the changing of political borders (in many countries, specifically the electoral district/constituency boundaries) usually in response to periodic census results. This takes place by law or constitution at least every decade in most representative democracy systems to maintain a geographic form of proportional representation.

A controversial approach to redistricting, gerrymandering, is the deliberate manipulation of political borders for electoral advantage, usually of incumbents or a specific political party.
