We were so excited about the Census' first-ever report exclusively focused on biking and walking that we devoted this entire episode of the Talking Headways podcast to an interview with its author, Brian McKenzie.

Bike commuting is up 60 percent since 2000, the Census data shows, and people with low incomes are by far the biggest proportion of the riding public.

People who bike and walk are hungry for reliable data. While government-sanctioned statistics on vehicle-miles-traveled are easy enough to come by, where would you go for foot-miles-walked or bicycle-miles-ridden? Strava? No. The Census.

Not that the Census data doesn't have its limitations, and Brian talks candidly about those. But the data gives us a glimpse of who's walking and biking for transportation, and where, and why they stop.

Dive deep with us. Here is a full half-hour just for you bike-ped dataheads. Enjoy. And talk at us in the comments.
