How did other countries get proportional representation?
One of the most common questions people ask is, “How did other countries get proportional representation?”
The political moment that opens the door to PR is unique in each country. The “how” PR happens done boils down to one thing:
In almost every country with proportional representation, parties were willing to negotiate, compromise and hammer out an agreement.
This does not mean every party agreed in every case.
While proportional representation levels the playing field for everyone, it’s not going to be in the short-term self-interest of every party at the same moment. Although in many cases, parties across the political spectrum did agree, including those on the right).
See below for a chart of how OECD democracies adopted PR.
Fair Vote Canada encourages parties to start the conversation that could lead to a multi-party agreement with a National Citizens’ Assembly on Electoral Reform.

This table includes only countries use that proportional representation currently and are rated as "free" democracies by Freedom House. This chart does not include countries with majoritarian or mostly majoritarian systems.
