According to newly released US Census Bureau’s American Community Survey data, in 2010, DC’s percentage of bike commuters rose to 3.1% of all commuters! With this increase, we now rank 5th among the 70 largest cities in the US. This is an unprecedented 44% increase over 2009’s rate (2.2%) and a 169% increase over the past ten years. Currently, only the cities of Portland (6.0%), Seattle (3.6%), San Francisco (3.5%) and Minneapolis (3.5%) rank above DC. A solid year of growth in the bicycle commuting rate as represented in the ACS data is a testament to the region’s commitment to bicycling as a primary mode of transportation for residents. It also underlines the ever-present need to expand our bicycle infrastructure, develop and grow innovative programs like Capital Bikeshare, improve enforcement and encourage new populations to ride bicycles.
