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 Stratford % Stratford Victoria % Victoria Australia % Australia

Households where rent payments are 30%, or greater, of household income -- 6.2 -- 9.1 -- 10.4
