Proportional representation is the idea that seats in parliament should be allocated so that they are in proportion to the votes cast. Although there are many different types of PR, this is the base requirement for a system to be described as proportional.
Rather than the winner-take all approach of other systems, PR ensures that votes carry equal weight. To do this, a single area elects more than one representative. The size of this area can vary according to the system, ranging from the size of the whole country to a county or local area.
