Accommodation type (7 categories)

Description: The type of building or structure used or available by an individual or household This could be: * the whole house or bungalow * a flat, maisonette or apartment * a temporary or mobile structure, such as a caravan

More information about accommodation types: * Whole house or bungalow: This property type is not divided into flats or other living accommodation. There are three types of whole houses or bungalows. * Detached: None of the living accommodation is attached to another property but can be attached to a garage. * Semi-detached: The living accommodation is joined to another house or bungalow by a common wall that they share. * Terraced: A mid-terraced house is located between two other houses and shares two common walls. An end-of-terrace house is part of a terraced development but only shares one common wall. * Flats (Apartments) and maisonettes: An apartment is another word for a flat. A maisonette is a 2-storey flat.

Quality information: We have made changes to housing definitions since the 2011 Census. Take care if you compare Census 2021 results for this topic with those from the 2011 Census.

Comparability with 2011: Broadly comparable. We have added a category called "part of another converted building (for example, former school, church or warehouse)". This means that there are some changes to the way people who lived in flats answered the question when comparing this variable with the one in the 2011 Census.

Ethnic group (9 categories)

Description: The ethnic group that the person completing the census feels they belong to. This could be based on their culture, family background, identity or physical appearance. Respondents could choose one out of 19 tick-box response categories, including write-in response options.

Comparability with 2011: Broadly comparable. The question about the ethnic group people feel they belong to is self-identified and is subjectively meaningful to the person answering the question. This means that how a person chooses to identify can change over time. We have included a new Roma category next to the Gypsy or Irish Traveller tick-box within the White category. We have also added a write-in option for those selecting African within the Black, Caribbean or Black British category. This means that a more specific ethnic background could be recorded.
