Following feedback from the 2021 Census topic consultation, we committed to collecting information on all housing topics. However, we noted that the user need for information on rooms and bedrooms was very similar, so we committed to reviewing the need for two separate questions and to explore the potential to use Valuation Office Agency data to produce estimates instead.

Information on the user need for visitors and communal establishments was not discussed in the topic consultation. We use information on visitors (those staying at an address overnight on census night that have no usual address in the UK) operationally to minimise the number of people missed from the census in England and Wales. Communal establishments refer to managed residential accommodation, for example, nursing homes and military barracks.

Each piece of research is part of a wider programme of testing and question development. Conclusions on our final recommendations should not be made by looking at any individual report. Further question development work is being carried out before our recommendations inform a government White Paper in 2018.

28 June 2017, Estimating the number of rooms and bedrooms in the 2021 Census: An alternative approach using Valuation Office Agency data

Following the 2021 Census topic consultation, we made a commitment to explore the use of administrative data from Valuation Office Agency (VOA) to produce estimates for number of rooms. This commitment has been updated to include producing estimates for number of bedrooms. We published a report on an alternative approach for producing estimates on rooms and bedrooms using VOA data and held a consultation to help us understand the impact of this change. A Welsh translated version of the consultation is also available.
