Household composition (7 categories)

Description: Households according to the relationships between members. One-family households are classified by: - the number of dependent children - family type (married, civil partnership or cohabiting couple family, or lone parent family)

Other households are classified by: - the number of people - the number of dependent children - whether the household consists only of students or only of people aged 66 and over

Quality information: There are quality considerations around consistency of census data on household and family composition and legal partnership status, and changes in the definition of "other household types" since 2011.

Comparability with 2011: Broadly comparable. This is derived from the legal partnership status derived variable. We have made changes to reflect that people can now marry someone of the same-sex and people of the opposite-sex can be in a civil partnership.

Religion (10 categories)

Definition: The religion people connect or identify with (their religious affiliation), whether or not they practise or have belief in it. This question was voluntary and includes people who identified with one of eight tick-box response options, including "No religion", alongside those who chose not to answer this question.

Comparability with 2011: Broadly comparable. This derived variable can be generally compared with the same variable used in the 2011 Census, but there are some quality issues in the data.
