This dataset provides 2001 Census estimates that classify usual residents in households in England and Wales by shared/unshared dwelling and central heating and occupancy rating by religion. The estimates are as at census day, 29 April 2001.

The occupancy rating provides a measure of under-occupancy and overcrowding. For example a value of -1 implies that there is one room too few and that there is overcrowding in the household. The occupancy rating assumes that every household, including one person households, requires a minimum of two common rooms (excluding bathrooms).

In general, a household's accommodation is defined as an unshared dwelling if all the rooms are behind a door that only that household can use.

Figures have been randomly adjusted to avoid the release of confidential data
