The criterion used to place a dwelling or household into the classification is the number of motor vehicles that are available for use by, or on behalf of, the residents or household members.
Number of motor vehicles is a flat classification with four categories – excluding residual categories.
The residual categories are defined in Glossary and references.
The full classification is available in the 'Available files' section on the main page.
If tick boxes are used for collecting data, and more than one response has been given, the greater number of motor vehicles indicated should be captured.
