Is it? I'm admittedly fairly ignorant on how other countries run their election systems, but... geographic representation seems uncommon (lots of parliamentary systems) and sophisticated solutions to drawing districts within countries that have geographic representation would have to be even more rare.
I am familiar with Parliamentary systems of 5 countries (Britain & former colonies) and they are mostly geographic, to my knowledge. Each Members of Parliament is voted in by voters residing within a geographic region/ward.
Interesting... looks like a lot of countries with parliamentary systems use proportional instead of geographic representation... but not the UK or Canada. Today I learned.
And some countries manage to achieve proportional representation while still giving each district their own choice of representative (e.g. Mixed-Member Proportional Representation in Germany and New Zealand).
