We downloaded the2006-2008 ACS county-to-county worker flow for Dane County, Wisconsin from http://ctpp.transportation.org/Pages/3yrdas.aspx.

The question we now have…can that data be compared to the county-to-county 2000 CTPP work trips  to determine any statistically significant increase/decrease?  If so, how would one calculate the margin of error?
