On March 15th Arlington Country published a report with data links on where bike commuters live. Its interesting how many people commute on a bike. Though bike commuting in some sections of the map is clearly driven by choice. I would speculate that in some of the neighborhoods, especially across the Columbia Pike corridor in the center of the map, where there are no bike trails, but bike commuters its driven by necessity.
The county provides the links to census data to do overlays to see how income and race could interested with bike commuting. It might also be interesting to do a comparison with other counties who have similar population density and income.
EDA has an interesting website with the data. http://clustermapping.us/
