I wouldn't be able to give you a number; however, I think that each electoral system has its challenges when it comes to local representation.
On the first-past-the-post side, there is discussion of how much local representation there is, but on the proportional representation side, it's the same issue. In South Africa, for their first democratic election, they implemented a proportional system. By the time they were to their second election, they were already questioning whether there was a proper connection between the local citizens and their representatives because of the proportional representation approach. They were wondering whether the proportional representation approach should be reformed.
I can't give you the number you're looking for, but no matter the system, there is the issue of local representation. That is, I understand, one of your five guiding principles in the work that you're doing, so obviously it's very important to this committee.
