Number of cars per household

About this topic

Number of cars per household shows how many registered motor vehicles are available to people living in a household. It is a measure of access to private transport rather than total travel activity.

This topic is useful for understanding mobility, transport choice, and access to jobs and services. It should be read with public transport availability, household type, income, and travel to work, because high or low car ownership can reflect very different local conditions.

Interpretation notes

  • This measures registered motor vehicles owned or used by residents that were garaged or parked at or near the dwelling on Census night.
  • Vehicle counts are a household access measure, not a direct measure of how often people drive or commute.
