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 Wellington (SA) % Wellington (SA) South Australia % South Australia Australia % Australia
Median rent 210 -- 220 -- 285 --
Households where rent payments are less than 30% of household income -- 90.3 -- 90.7 -- 89.6
Households where rent payments are 30%, or greater, of household income -- 9.7 -- 9.3 -- 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).
