Over 20% of commuters in Bloomingdale, Mount Pleasant, and Petworth get to work each day primarily using a bicycle. That doesn’t even include people who use bikes to reach Metro.
It shows how hugely popular bicycling can be as a mode of transportation, even in the United States. What’s more, this data actually undercounts bicycle commuters by quite a lot.
It’s originally from the US Census’ American Community Survey, which only counts the mode someone uses for the longest segment of their commute. People who bicycle a short distance to reach a Metro station, then ride Metro for the rest of their commute, count as transit riders rather than bicyclists.
