The quartile method is the most objective method of comparing change in the mortgage payment profile of a community over time.

A detailed explanation of how Housing Loan Repayment quartiles are calculated and interpreted is available in specific data notes.

Please note, interest rates at the 2021 Census were at a record low in Australia. The first interest rate rises by the Reserve Bank began an upward cycle from May 2022. Please use mortgage payment data with caution as data from the 2021 Census pre-dates all official rate rises in the current cycle.

Derived from the Census questions:

'How much does your household pay for this dwelling?' and 'Is this dwelling (owned outright, owned with a mortgage etc.)'
