According to the League of American Bicyclists’ analysis of the recently released 2009 American Community Survey (ACS), national bike commuting rates held steady from 2008 to 2009 at 0.55%. From the LAB report:
Despite predictions that the number of Americans biking to work would fall after gas prices returned to ‘normal’ in 2009, the percentage has held steady at 0.55 percent. The Bicycle Friendly Communities (BFC) among the 70 largest cities also held steady with a 1 percent increase, while non-BFCs increased their commuter share by 26 percent. BFC cities still have on average about twice the percentage of commuters as non-BFC cities.
The League used the ACS data to pull together a pair of tables (linked below) showing estimated bike commuting rates for the 70 largest U.S. cities, as well as the estimated percentage of change in bike commuting rates from 2000 to 2009.
