The National Bike Challenge website has the above statistic (title of this post) on today’s slide show. Throughout the challenge I have wondered where the NBC organization gets most of their statistics (like many websites, they never site their sources). With a quick Google search I found my answer. The People for Bikes organization as a Statistics Library site. Now this is my kind of library, nothing but statistics that links to the research publication. It’s a factoid nerd’s paradise.
I thought for today I would just list a few that I found the most interesting, for a full listing go here. The ones on pollution exposure really surprised me.
On the same urban route, car drivers were exposed to more airborne pollution than cyclists, despite the cyclists’ higher respiration rates.

Kids who ride a school bus inhale up to a million times more vehicle emissions than the average person outside the bus

Despite the fact that cyclists breathe two to three times more air than motorists, motorists breathe about 60% more carbon monoxide and significantly more pollutants than cyclists.

Over time, people who commute by car daily tend to gain more weight than those who do not, even if they are physically active at other times.

After a bike and pedestrian lane was installed on a South Carolina bridge, 67% of users indicated that their activity levels had increased since the opening of the lane.
