"Only white yuppies bike in Toronto". At least that's what I was told when asking people informally. But there is some actual data on the issue, including a small survey in Toronto noting that visible minorities were less interested in cycling than white respondents and a Canada study finding that immigrants bike less than non-immigrants. Even in bike-friendly countries like Denmark they're realizing that their incoming immigrant population cycles less than the "average" Dane. And if there is a link between a person's ethnic background and the likelihood that they'll use their bike to get around, it could be an issue in encouraging more cycling in Toronto since 47% of Torontonians are visible minorities and over 50% are foreign born.
To find out more on this topic, I'm inviting all Toronto cyclists (that's you!) to fill out a quick 5 minute survey aimed at gathering information on who you think cycles in Toronto as well as who actually does. There's also a space to add your email address, if you'd like to see my final findings.
