A change has been made to the calculation of occupancy rating (bedrooms). This affects the original version of this table that was first published 30 January 2013. In the original versions all households who reported having no bedrooms were reported as over-occupied (i.e. they had fewer bedrooms than required), but this is not necessarily correct as these are usually one-room households and should have been recorded as having one bedroom. The updated versions of these table’s has recalculated the occupancy rating, treating these households as if they have one bedroom. Also the calculation of the average number of bedrooms per household has been similarly changed to be consistent and treat households that recorded zero bedrooms as if they have one bedroom.
