Proportional Representation and Party System Fragmentation

Quick fact

Countries using proportional representation (PR) tend to have more parties than those using winner-take-all systems; a low electoral threshold can help small parties win seats in parliament.

Why this is interesting

Why do some countries have just two major political parties, while others have dozens? The answer lies in how votes are counted.
