Following up on Eric de Place’s look at some of the demographics of bicycling, We Bike Eugene has an interesting graphic by UO grad student Kory Northrop detailing more about cycling trends across the nation. Take a look (click to embiggen):

Not surprisingly, the Northwest holds its own, nabbing the #1 (Portland) and #3 (Seattle) spots for most bike commuters.

But one staggering finding is the division between men and women who ride. Only 27 percent of bike commuters are women. That trend is less pronounced in Oregon (40 percent female) than Washington (30 percent), and Idaho and Montana actually have a closer ratio of riders, though fewer bike riders over all. (The chart also shows female rides increasing 2008 and 2009 while male riders took a dive.)

Check it out and let us know what you find most surprising.
