Parliamentary Voting System and Constituencies Bill

Is not one of the problems with the Bill the fact that the Lewis Baston material on countries that use population bases does not include how those population statistics were produced? One would have thought, when obviously the Bill was going to be surrounded by discussion about population, that research would have been done by officials in the department to establish the basis on which other countries use population figures. Have they a different way of drawing up census information? None of that information has been made available, which makes it very difficult for us to argue the question of population during the passage of this legislation.
