Hey - hope this goes through. I'm Mark Evans and I developed the commuter map. Ed Christopher told me about this listserv. I'm happy to answer any questions that you may have.
I calculated a CV using the estimate and the MOE. I've seen some warnings about the high level of error in some of the ACS data with recommendations to include only data with CV < 30-40%. Unfortunately, this removes almost all the data, so the default setting I used is 80%. Even at this high level, it excludes a portion of the estimated commuters at the tract level. In addition, anyone who works and lives in the same tract would not be included.
Thanks for taking a look!
