This is interesting data, but I'm curious how seasonality was factored into the data analysis. I suspect the response would be significantly different if the survey was taken in the winter versus the summer. Rich

Subject: [Bikies] Madison bike commuter maps Message-ID: <[email protected]> Content-Type: text/plain; charset="utf-8"; Format="flowed" The Census Bureau recently released 5-year American Community Survey data showing variation in commuting patterns at the census tract and block group scales. The maps in the link below help to illustrate those differences: https://dl.dropboxusercontent.com/u/39132997/Bike_commuters.pdf The patterns in the first two are not too surprising but help underscore that bike commuters represent a significant share of workers in the near east, near west and downtown neighborhoods.I was glad to see the pattern in the third map (change in bike commuting) indicating an uptick in areas adjacent to the major off-street bike corridors on the east and west sides. Cheers, Dave PS: At these smaller geographic scales, there's a lot of sampling error in the ACS estimates, so please use with caution. -- David Long Applied Population Lab University of Wisconsin Phone: 608.262.3097 http://www.apl.wisc.edu/ -------------- next part -------------- An HTML attachment was scrubbed...

When the ACS data came out in September, I had a look at the aggregate numbers over the past few years for state, county, and city.
