An election system that allocates to each political party representation in the legislature equal to its percentage of the total vote is called a proportional representation system.
Proportional representation (PR) refers to a type of electoral structures under which subgroups of an voters are contemplated proportionately inside the elected frame. The idea applies especially to geographical (e.g. states, regions) and political divisions of the electorate.
Electoral structures known as "proportional" in a narrower sense mean proportional to votes, rather than population: even though the united states house of Representatives is proportional geographically (among and inside states), its electoral gadget is considered to be no longer proportional, however majoritarian. The most time-honored forms such techniques require using a couple of-member vote casting districts. PR structures that obtain the highest tiers of proportionality have a tendency to apply districts with large numbers of seats, normally 5 to 9 seats, masking an entire province or a whole state.
