About this dataset

This dataset provides Census 2021 estimates that classify households in England and Wales by age of youngest dependent child and by household type. 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

Dependent children in household and their age (7 categories)

Description: Classifies the number of dependent children in a household, by the age of the youngest child.

Comparability with 2011: Highly comparable


Household type (6 categories)

Description: Classifies households in an alternative way to the "household composition" classification used in most standard census results. The type of family present classifies a household. However, households with more than one family are categorised using this priority order: * married couple family * civil partnership couple family * cohabiting couple family * lone parent family

Within a family type, a family with dependent children takes priority.

The alternative definitions used in tables that use this classification are: * married couple household * same-sex civil partnership couple household * cohabiting couple household * lone parent household

Comparability with 2011: Broadly comparable We have added opposite-sex civil partnership and same-sex marriage categories into the variable that have come available since 2011. These can be collapsed to civil partnership and marriage, the same as the 2011 variable. Cohabiting couples (adults not in a marriage or civil partnership) include both same-sex and opposite-sex couples in both 2011 and 2021.
