About this dataset

This dataset provides Census 2021 estimates that classify usual residents in England and Wales by religion. The estimates are as at Census Day, 21 March 2021.

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

Religion (detailed) (60 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 the variable includes people who answered the question, including "No Religion", alongside those who chose not to answer this question.

This variable classifies responses into the eight tick-box response options. Write-in responses are classified by their "parent" religious affiliation, including "No Religion", where applicable.

Comparability with 2011: Broadly comparable. We have added the categories "Other religion: Alevi", "Other religion: Valmiki" and "Other religion: Yazidi" to this derived variable. The two categories "No religion: Jedi Knight" and "No religion: Heavy Metal" have been included in the parent "No religion" category.
