Truck Inventory and Use Survey (TIUS) 1967 [supporting datasets]

The census of transportation, together with the censuses of business, manufactures, and mineral industries, comprise the economic census program of the Bureau of the Census. This program is required by law under Title 13 of the United States Code, sections 131 and 224. The present economic census collects statistics for the year 1967. Future censuses are scheduled by law for 5-year intervals. A large segment of transportation data is available from regulatory and other government agencies, and private organizations. For that reason, the statutory provisions concerning the census of transportation directed the Bureau to collect the kinds of data that were not publicly available from other sources. The objective was to avoid duplication and fill important gaps in transportation information. The census of transportation was undertaken for the first time on a National basis in 1963. The 1967 census was taken under three separate surveys-National Travel, Truck Inventory and Use, and Commodity Transportation, each on a sample basis. The surveys are independent of each other, and the results are published in three distinct series of reports.
