Abstract

A computer program is designed to produce all of the electoral constituencies for an English local authority, within the constraints imposed on the Parliamentary Boundary Commissioners. This builds on the seminal work of Gudgin and Taylor, and introduces size constraints, evaluates shape, and evaluates the electoral consequences of swings in voter opinion.
