One ancillary question on the UK elections.
In the UK elections it seems that most constituencies have very specific regional identity e.g. Dover, Falkirk and also “Crewe and Nantwich”, “Ellesmere Port and Neston”, “Knowsley North and Sefton East”.

Order! Order!
The Member for Inverness, Nairn, Badenoch and Strathspey will withdraw their comments about the relationship between the Member for Cumbernauld, Kilsyth and Kirkintilloch East’s mother and the Member for Kingston upon Hull West and Hessle … and could somebody bring my teeth back please."

However does this also mean that the constituency boundaries are essentially fixed based on local government borders? Consequently do the enrolments vary substantially between constituencies and over time?
Or is it a consequence of voters being allowed to vote in one of possibly several constituencies that they have residential entitlement and hence you don’t actually know how many eligible voters are in a constituency?
In Australia the Electoral Commission redistribute the boundaries within each state to keep the number of voters in each electorate within reasonably tightly defined limits. This happens every seven years or sooner (if 1/3rd of the electorates are outside 10% variance from the state average.).
The consequence of this is that the electorates move and can become disconneted with their nameplace. For example there was once a electorate named Grafton, centred on town of Grafton, but eventually the electorate moved to the point where Grafton was not in Grafton.
To get around that as they are created new electorate names take on non-regional names, usually something connected with historical or political figures e.g. Banks, Barton, Benelong, Blaxland, Bradfield etc.
The town of Grafton is now in the electorage of Page (named after Earle Christmas Grafton Page who was Prime Minister for 20 days in April 1939 after Joe Lyons died in office)
