Incidentally, I don’t know if this is of any interest, but I’ve been playing around with re-apportioning the U.S. House of Representatives. (I wrote a little Python script to implement the apportionment algorithm, and am using U.S. 2000 census data for the state populations. The program’s results check with the actual breakdown of the House, so I think it’s working correctly.)
Assuming the House stays fixed at 435 seats, and that the UK has a population of 59,834,900 (that’s according to its own 2001 census), then the UK as a state would have 76 seats. If instead we take its population to be 60,609,153 (that’s a 2006 estimate from the CIA World Factbook), then the number of seats increases to 77. In either case, California — now the second-most populous state — shrinks in representation from 53 to 43 seats.
Assume again that the House doesn’t grow. If the four countries of the UK joined as separate states, then, using their populations from the 2001 census, their representations in the House would be: England 64, Scotland 6, Wales 4, and Northern Ireland 2.
If we want to enlarge the House so that the representations of the North American states relative to each other don’t change too much, then you’d have to add over 90 seats — to keep California’s number pegged at 53, for example.
Assuming the House is increased to 530 seats, UK’s representation would be 93, California’s 53. If the UK countries joined as separate states, their representations would be: England 78, Scotland 8, Wales 5, Northern Ireland 3.
Well, that was a good morning’s work. Time for lunch.
