Data collected in the latest Census shows the home ownership rate of people aged 30 to 34-years-old sat at 50 per cent in 2021, a drop of 14 per cent since 1971.

For those aged 25 to 29, the decrease was also 14 per cent over the same period, dropping to 36 per cent in 2021.

Some of those people aged below 30 who owned their own home in the 1970s are among the Aussies with the highest rate of ownership in 2021.

Baby Boomers - those born between 1946 and 1964 - make up the highest rate (82 per cent) of home owners in 2021.

The data released on Tuesday by the Australian Institute of Health and Welfare was drawn from information gathered in the latest Census, including that there were nearly 9.8 million households in 2021.

Of those, 67 per cent were occupied by "owners", with roughly half of those subject to mortgage.

About a third of households, or 2.9 million, are occupied by renters.

"There has been a sharper increase in the proportion of young Australians renting compared with older Australians," the institute said as part of its data release.
