After every election, we study voter turnout. In fact, I can make those studies available to the committee, if you'd like. We examine the circumstances of those who did not vote in an effort to understand why they decided not to. Three broad categories usually emerge.
First, about 40% of people tell us they didn't vote owing to various barriers. They weren't available, they weren't in their riding and couldn't make it to the appropriate location to vote that day, and so forth.
Second, 45% of people tell us they don't care about politics. They don't think their vote will necessarily count.
Third, about 8% of people report not voting for procedural reasons, such as the complexity of the voter registration process.
These are longitudinal studies that are published, so they are available.
