SUMMARY OF DATASET
----------------------------------------------------------------

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 1967. 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.

C. DATA & RELATED FILE OVERVIEW
----------------------------------------------------------------

For the 1967 Truck Inventory and Use Survey, the data is broken up into data for the entire United States and Data for each of the 50 states and the District of Columbia. For each state, there are 6 tables. These tables include:
* Sampling Variability of Data
* Table 1 ALL TRUCKS Percent Distribution of Major Use Classes, by Vehicle and Operational Characteristics 1967
* Table 2 ALL TRUCKS Percent Distribution of Size Classes, by Vehicle and Operational Characteristics 1967
* Table 3 ALL TRUCKS Percent Distribution of Annual Mileage Classes, by Vehicle and Operational Characteristics 1967
* Table 4 TRUCKS EXCEPT PICKUP AND PANEL Percent Distribution of Ranges of Operation, by Vehicle and Operational Characteristics 1967
* Table 5 TRUCKS EXCEPT PICKUP AND PANEL Percent Distribution of Truck Types and Axle Arrangements, by Vehicle and Operational Characteristics 1967

Each state contains each of these 6 tables with the following file naming pattern: 

bts_TIUS_1967_data_[State Name]_[Table Name]

An example of a complete table name is:

bts_TIUS_1967_data_Alabama_SAMPLING VARIABILITY OF DATA

In this example, this file is the TIUS 1967 Sampling Variability of Data table for the state of Alabama.

For the United States data tables, there are 37 individual data tables with their own unique name. To see the complete list of data table file names, please consult the file structure documentation below. In addition to the data tables, there are 8 files that contain the map and figures information from the report. These file names and their location in the zip file are also included below.

	1. Sampling Variability of Data
	2. Table 1 ALL TRUCKS Percent Distribution of Major Use Classes, by Vehicle and Operational Characteristics 1967
	3. Table 2 ALL TRUCKS Percent Distribution of Size Classes, by Vehicle and Operational Characteristics 1967

In addition to the data tables, there are 3 documents that are included to share information about these datasets. One is the README text file, this document. The README.txt file that includes human-readable information about the data, variable definitions, contact information, and other contextual information. The other is the machine-readable JSON file in DCAT US version 1.1 schema that contains the data’s metadata. Lastly, there is a Data Management Plan PDF document that was created for current and future management of the data and associated files. All these files contain significant preservation and creation information about these datasets and provide context to the survey.


----------------------------------------------------------------
D. METHODOLOGICAL INFORMATION
----------------------------------------------------------------

1. Description of methods used for collection/generation of data: 
   Due to limited documentation the methodology behind the Truck Inventory and Use Survey (TIUS) 1967 dataset isn't complete.

2. Instrument- or software-specific information needed to interpret the data:
   The data and documentation files can be opened with any text reader. Some versions of the documentation files may be opened with PDF reading software.


----------------------------------------------------------------
E. DATA-SPECIFIC INFORMATION  
----------------------------------------------------------------

Because of the innumerous amount of data tables created for the year 1967 TIUS, 351, counting the number of rows and columns is too extraneous for this project. Additionally, because these data tables are summaries of the data and not the raw data itself, there are no variables to define, so there is no data dictionary. In the case of null or blank data, this means that the data was either not reported, not applicable, or as reported depending on the question. For these data tables, each null or blank value is explained with footnotes and in the reports.
