Last week I made a map showing the non-car commuter mode share for every census tract in Los Angeles County. This week, I've got the same for all of Washington state (which actually has a significantly lower population than LA County).
I intend to get all of the states done eventually, then I'll hopefully be able to combine them all into a single map and table. Part of the reason I'm doing this is to make Google Fusion/Maps a more useful tool for others interested in mapping; right now there don't appear to be census tract boundary maps uploaded into the system for most locales, and without those any mapping at the tract level isn't really possible. This'll probably take a few weeks of work off and on, so if any readers are anxious to get the numbers for their states, just let me know and you can jump to the head of the queue.
Here's the map for Washington:
And here's a link to the full-sized map.
No big surprises in terms of the commute mode share -- Seattle is the only area in the state where more than half of residents commute without a car, though some areas come close and the ferry dock areas of Bainbridge Island and Bremerton both have high non-car mode shares. Seattle is a very centralized city, as opposed to the poly-centric nature of Los Angeles, and that's reflected in a single concentrated area of car-free commuting centered on Downtown and adjacent neighborhoods. The expansion of Link light rail may shift this to more of a car-free corridor rather than a car-free core.
For those interested in embedding the map on their own site, you'll want to go here, click the tab that says "Washington," pull down the tab that says "Publish," and copy from there. The embedded map will show whatever you're looking at when you hit "Publish" -- in my case I was viewing Chicago, for example -- so keep that in mind if you want to highlight a specific area.
