In mid-September, the Census Bureau released the results of the 2013 American Community Survey.  We have extracted the mode split and average commute time information for 373 metropolitan statistical areas (MSAs). The summary shows the 2013 estimates but also compares changes between 2013 vs. 2012, 2013 vs. 2011, 2013 vs. 2010 and 2013 vs. 2009; noting whether the change between those periods was statistically significant.  Download the pdf copy of 2013 American Community Survey mode split summary for all MSAs. An * indicates that the estimate is significantly different (at a 90% confidence level) than the estimate from the most current year.
