While we spend a lot of our time capturing, analysing and talking about the primary data we collect, secondary data is also key to what we do, often giving us the context that fits around our research results. And, while there were some very well-publicised issues around the most recent census, the Australian Bureau of Statistics (ABS) is definitely still king when it comes to sourcing secondary data in Australia.
One area we've been looking at recently is the number of motor vehicles per household. As shown in the table below, there are some clear differences by state, with almost two thirds of West Australian households having two or more motor vehicles, against just over half of those in New South Wales. While you might expect West Australians (and Queenslanders) to have more cars, given the large distances they might need to travel, do one in five Tasmanians really need three or more vehicles for their household?
At the other end of the scale, one in ten NSW households report being car-free on census night, which would be interesting to line up against their location (e.g. inner-city suburbs), or use of car-sharing (e.g. GoGet) and ride-hailing (e.g. Uber).
For anyone who'd like to do some more digging, the chart below contains the raw data by state, and for those who really want to get into the weeds, further information is available from the ABS.
