FILE STRUCTURE AND CONTENT


PRODUCT STRUCTURE

The Motor Vehicle Use, Australia, 2018 TableBuilder product is structured as two separate datasets:

  • Motor Vehicle Use, 2018 (Includes summations of Kilometres travelled, Tonnes carried, Tonne-kilometres travelled, Fuel consumed); and
  • Motor Vehicle Use, 2018 - Number of vehicles (Includes summation of Number of vehicles and the variables of State/territory of registration, Vehicle type and Year of manufacture groups).


FILE STRUCTURE

The format of the Motor Vehicle Use, Australia, 2018 TableBuilder product is structured with two levels, a vehicle level and a use level. The vehicle level contains information such as State/Territory of registration, type of vehicle, fuel type, year of manufacture groups and other vehicle characteristics. The use level covers types of use, including Area of operation, State/territory of operation, business use, and other types of use. A complete data item list can be accessed from the Downloads page.

Mandatory field and totals

The Motor Vehicle Use, Australia, 2018 TableBuilder contains a mandatory field called Total, which is from the Use Type fields contained in the Use level. By default this field will be present in any new table. Due to some Use types being sub totals, the automatic total function in this product has been turned off for Use types, with totals being generated through the mandatory field of Total.


CONTENT

Zero Value Cells

Tables generated from sample surveys will sometimes contain cells with zero values because no respondents that satisfied the parameters of a particular cell in a table were in the survey. This is despite there being vehicles in the general population with those characteristics. This is an example of sampling variability which occurs with all sample surveys. Relative Standard Errors cannot be generated for zero cells.

Due to the rounding of most summations, there will be some instances of cells showing zero values that are a valid response, these are indicated by having a generated Relative Standard Error.
