Although the total number of households in social housing (i.e. public, community and SOMIH housing) has increased over the last 10 years (from 375,038 in 2006 to 394,289 in 2016) the proportion of Australian households living in social housing has been falling.
If the proportion of households in social housing (4.8% in 2006) had been maintained through to 2016 (when 4.3% of all households lived in social housing) then an extra 49,302 households would have been living in social housing.
