Claim: “Voter turnout is 7% higher on average in countries with proportional representation.”

Fact Check

The claim above is true.

Research is clear that voter turnout is higher in countries with proportional representation than in countries with “winner-take-all” systems.

Sometimes proponents go further than this and say proportional representation will lead to higher turnout in BC. There is not much evidence that adopting proportional representation will lead to increased turnout in countries that were using first-past-the-post, simply because most OECD countries began using PR such a long time ago that there is little comparative data available.

Some notable research on turnout and electoral systems:

  •  Multiple researchers have found voter turnout is higher in countries with proportional systems:- Lijphart (2012) looking at 36 democracies over 55 years found turnout to be 7% higher.
    – Blais and Carty (1990) – 8% higher
    – Norris (1997) – 6-10% higher
    – International Democracy and Electoral Assistance (1999) – 12% higher among youth
  • Voter turnout has been declining across OECD countries for decades regardless of electoral systems.
  • A study in Switzerland comparing elections in about 2500 municipalities (communes) found that turnout was 3-7% higher in municipalities using proportional representation compared to first-past-the-post. This study was notable because it compared turnout rates using two systems within the same country.
  • A study in the US compared turnout data for 215 elections in 49 jurisdictions that used either cumulative voting (a semi-proportional system) or plurality voting (first-past-the-post). This study was notable because it compared turnout rates using two systems within the same country, but more significantly, this study also looked at turnout rates before and after a switch to cumulative voting. Researchers found that cumulative voting increased turnout by about 5%, an increase that was sustained for the second election.
  • After New Zealand switched from first-past-the-post to proportional representation there was a small increase in voter turnout the first election with PR, then voter turnout fell into the gradual pattern of decline seen across the OECD.
  • There is no research looking at a significant number of OECD countries that have switched from winner-take-all to proportional systems to assess the impact on voter turnout. This is because most OECD countries have had proportional systems for up to 100 years.
