Mortgage & rent

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

Households where rent payments are 30%, or greater, of household income -- 9.3 -- 9.5 -- 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).
