Region composition

Electoral Calculus Regions are specially designed to help analyse electoral geography. They have been chosen so that they are approximately of equal population, and also so that they are as politically homogeneous as possible. They are kept constant over the decades so that regional-based historical analysis can be easily performed. They do not coincide with current administrative region definitions, which instead are closer to our Areas.

There are twenty regions. They are listed below, along with their constituent counties or unitary local authorities. Note that "South London" contains three boroughs which are north of the Thames in order to keep the two halves of London roughly equal size.
