About this dataset
This dataset provides Census 2021 estimates that classify all household spaces with at least one usual resident in England and Wales by number of rooms. The estimates are as at Census Day, 21 March 2021.
National Park data are created by plotting unique properties as identified by their Unique Property Reference Number or postcodes into National Park boundaries current at December 2022. This differs from the OA best fit methodology used for other geographic level data.
Protecting personal data
Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we:
- Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority.
- Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.
About the variables
Number of rooms (VOA) (10 categories)
Description: A room can be any room in a dwelling apart from bathrooms, toilets, halls or landings, kitchens, conservatories or utility rooms. All other rooms, for example, living rooms, studies, bedrooms, separate dining rooms and rooms that can only be used for storage are included. If two rooms have been converted into one, they are counted as one room.
The number of rooms is recorded by address, this means that for households living in a shared dwelling the number of rooms are counted for the whole dwelling and not the individual household.
This definition is based on the Valuation Office Agency's (VOA) definition.
Quality information: It is inappropriate to measure change in number of rooms from 2011 to 2021, as Census 2021 used Valuation Office Agency data for this variable. Instead use Census 2021 estimates for number of bedrooms for comparisons over time.
Comparability with 2011: Not comparable. This variable cannot be compared with the variable used in the 2011 Census. This is because in Census 2021 the data are collected using administrative data instead of data from Census 2021.Read more...
