I posted about a Red / Blue national map of bike commuters yesterday, comparing the states vs the national average. Today, let’s look at California.
According to the US Census American Community Survey numbers for 2011, about 0.6% of Americans report riding their bicycles to work. 1.1% of Californians, by comparison, claim to bike to their jobs. This maps shows the comparative number of bike commuters for California counties. Red counties are at or below the 1.1% threshold, while blue counties have more than the state total of 1.1%.
You’ll notice not all counties are represented. The yearly ACS estimates only cover places with population over 65,000, so no data is available for those sparsely populated counties in northern California and the Sierras. San Benito County (home to Hollister and San Juan Bautista) also falls just short with 56,000 residents.
The exception is San Mateo County on the San Francisco Peninsula, with a population of three quarters of a million people. I think that’s just a glitch in the mapping software. The ACS for 2011 says 1.2% of commuters in San Mateo County rode their bikes, so it would be a blue county.
Yolo County, home to Davis, has the highest percentage of bike commuters among California counties at 8%. Yuba County north of Sacramento has the lowest proportion with only an estimated 0.1% of commuters riding their bikes. Interestingly, Yuba is one of the few counties where female commuters apparently outnumber men (0.3±1.3% vs 0.0±0.6%, according to Census estimates). In Yolo County, men and women are at parity.
(I realize this stuff is boring, but I find myself Googling for this info all the time, so I’m posting here for my own convenience.)
