Both biking and walking to work grew between the year 2000 and the end of that decade, according to data released by the Census Bureau.

Information collected through the American Community Survey between 2008 and 2012 shows that 3.1 percent of 306,336 workers biked to their job, up from 1.2 percent in 2000. Walking was also up, although not significantly: From 11.8 percent to 12.1 percent.

That’s the second highest walk-to-work rate among cities with a population over 200,000 people and the seventh highest bike-to-work.

And here’s why you shouldn’t conflate D.C. proper with the surrounding metropolitan area.

Similarly, 12.1 percent of District of Columbia workers walked to work, com- pared with only 3.2 percent of the Washington-Arlington-Alexandria, DC-VA-MD-WV, metro area.15 For several regions, comparatively low rates of nonmotorized travel within surrounding suburbs contribute to lower overall nonmotorized com- muting rates for the metropolitan area than for the central city.

Nationwide, commuting by bike grew from 488,000 people in 2000 to 786,000 in 2008-2012.
