Data confidence level:
How many cars does each Australian household own? Australians are car dependent, but do they share their vehicles, or is there more a one car per person policy? This FACT indicates the average number of motor vehicles per household in each Australian capital city for the year 2011. The city with the highest number is tied between Darwin and Perth, at 1.8. The city with the lowest number is Sydney, at 1.6. Compared with the number of people per household (taking into account the number of adolescents or children present, who are unable to drive), this makes for a high number of people who own their own car.
This FACT is also ranked from low to high (low is good) in the Sustainability category.
