Each year, the Census Bureau releases mode split information obtained through the American Community Survey. Best Workplaces for Commuters has complied a document containing estimates of total workers, mode shares, and average commute times, and columns showing statistical significance by comparing 2019 with 2015 to 2018.
According to the US Census, “Each metropolitan statistical area must have at least one urbanized area of 50,000 or more inhabitants. Each micropolitan statistical area must have at least one urban cluster of at least 10,000 but less than 50,000 population.” Over 500 MSAs are listed alphabetically and pages are grouped by commute mode share. An asterisk (*) indicates that the estimate is significantly different (at a 90% confidence level) than the estimate from 2019. An ‘N’ entry in the estimate and margin of error columns indicates that data for this geographic area cannot be displayed because the number of sample cases is too small.
Please note that the Census Bureau does not re-tabulate past-year estimates based on the current year’s (2019) geographies; the comparison is with the existing geography of each data year.
