A comment on Pedal Me bans staff riders from wearing helmets for safety reasons. Parent comment
My impression is:
1. Dutch-style utility riders using a bike to get around town for errands -> Rare helmets
2. Lycra-clad competitive cyclists with drop handlebars -> Widespread helmets
3. City cycle hire scheme users -> Rare helmets
4. Parents cycling with young children -> Widespread helmets
5. Poor people commuting on beat-up mountain bikes -> Rare helmets
6. Organised cycling events with mandatory helmets -> Widespread helmets
7. Teenagers riding with their friends -> Rare helmets
So the popularity of helmets depends on your locale (does your area have utility riders?) - and whether you measure per-mile or per-bike-owner :)
But fair, I don't have numbers.
