The Travel Time to Work table from the 2023 American Community Survey (ACS) 5-year estimates was joined to 2024 tract-level geographies for all 50 States, District of Columbia and Puerto Rico provided by the Census Bureau. A new file was created that combines the demographic variables from the former with the cartographic boundaries of the latter. The national level census tract layer contains data on the number and percentage of commuters (workers 16 years and over who did not work from home) with a range of travel times to work. A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/1529086 The Travel Time to Work tract shapefile can be used within the public, the federal government, rail industry, state DOTs, and academia for routing, mapping and analysis.
