There are many variations on seat allocation within party-list proportional representation. The three most common are: the d'Hondt method used in Israel and Austria, among other places, the Sainte-LaguŽ method, used in many Scandinavian countries, New Zealand, and the German Federal State Bremen, and the largest remainder method. List PR may also be combined in various hybrids (e.g. using the Additional member system).
The Sainte-LaguŽ method and the LR-Hare method rank as the most proportional followed by LR-Droop; single transferable vote; modified Sainte-LaguŽ, d'Hondt and largest remainder Imperiali. While the allocation formula is important, equally important is the district magnitude (number of seats in a constituency). The higher the district magnitude, the more proportional an electoral system becomes.
