The Household Size by Vehicles Available table from the 2024 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 households by household size by number of vehicles available. A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/1529030 The Household Size by Vehicles Available tract shapefile can be used within the public, the federal government, rail industry, state DOTs, and academia for routing, mapping and analysis.

Users are advised to read the rest of the metadata record carefully for additional details. The demographic data was downloaded from data.census.gov (table B08201) - ACS 5-year estimates from 2024. These were joined to the 2020 Census Tracts from the 2024 TIGER/Line National Sub-State Geography Geodatabase file for the entire US (excluding the island geometries - State FPs 60, 66, 69, and 78) using a Python script to join the GEOIDs correctly. asNeeded Justyna Goworowska Bureau of Transportation Statistics (BTS) Spatial Transportation Data Analyst 202-570-1865 1200 New Jersey Ave. SE Washington DC 20590 United States j.goworowska@dot.gov custodian
