Mortgage & rent

Proportions are calculated using all tenure types for occupied private dwellings. This excludes visitor only and other non-classifiable households.

Rent weekly payments Airds % Airds New South Wales % New South Wales Australia % Australia
Median rent 144 -- 300 -- 285 --
Households where rent payments are less than 30% of household income -- 74.4 -- 88.4 -- 89.6
Households where rent payments are 30%, or greater, of household income -- 25.6 -- 11.6 -- 10.4

Proportions in this table are calculated by taking the number of households whose rent payments were 30% or more of an imputed income measure and expressing this number as a proportion of the total number of households in an area, including those households which are not renting their dwelling (excluding the small proportion of visitor only and other non-classifiable households). The nature of the income imputation means that the reported proportion may significantly overstate the true proportion. Further information on the method to impute income is available in the income fact sheet.
