This is my third map mashup. It compares the share of commuters who are cyclists with the location of Toronto Cyclists Union membership. The map shows that the richest deposits of potential bike union members are where there are already a high number of cycling commuters.
Like bike shops and bike accidents these areas are located in downtown and west of downtown. These could be considered the easy picking areas for increasing bike union membership. It's possible that the bike union's current attempts to create ward captains in every ward of Toronto is actually slowing the growth of the bike union membership. A concerted effort to recruit members in the core might have a bigger impact on the bike union and provide more resources to recruit members in the suburbs later on. I'd be interested to see if there are alternative conclusions.
