Here's something that will surprise no-one: Bicycle commuting is growing much faster in bicycle-friendly communities. And it's growing more slowly, or not at all, in communities that aren't bicycle friendly.
So we learn from an American Community Survery, which was reported in the League of American Bicyclists blog.
Across the United States, bicycle commuting increased 47 percent from 2000 until 2011. During that time, it shot up by 80 percent in bike-friendly communities and but inched up by 32 percent in non-bike friendly communities.
Some good news is that even the increase in non-bike friendly communities has outpaced population growth. Still, it pretty much goes without saying that the best way to get more people to commute by bicycle is to create conditions that are conducive and make people safe and comfortable in riding their bikes to work.
