Housing rental quartiles
About this topic
Housing rental quartiles group renting households into four evenly sized rent bands so rental costs can be compared across places and across Census years. They show the relative rent profile of the renting population rather than fixed weekly rent brackets.
This topic is useful for comparing change over time because direct rent amounts are affected by inflation and broader market shifts. It is best read with household income and tenure when assessing rental affordability and housing stress.
Interpretation notes
- This is a derived rent distribution for renting households, so quartiles show relative rent position rather than fixed weekly rent bands.
- Quartiles are more useful than raw rent ranges for comparing rental profiles across areas or years.
Key insight
In 2021, the highest rent quartile held the largest share among households renting their home in Blackwood (SA), accounting for 36.7%.
