About this dataset

This dataset provides Census 2021 estimates that classify families in England and Wales by family type, by dependent children and by age of the Family Reference Person. The estimates are as at Census Day, 21 March 2021. A concealed family is one that does not include the Household Reference Person.

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

Concealed family type (13 categories)

Description: This categorises the type of concealed family, whether it is a lone parent or couple family, with or without dependent or non-dependent children. A concealed family does not include the Household Reference Person (HRP).

Example: George and Amy live at the same address as their daughter Emily and her husband and daughter. Because Emily is not a dependent child and has her own family, there are two families in this household. * Family one are George and wife Amy. George is the Family Reference Person (FRP). * Family two is daughter Emily, husband Simon and their daughter Eve. Emily is the FRP.

As there is more than one family in the household, The FRPs are prioritised to decide who is the HRP. * In this household, George is the HRP. * This means that Emily's family is a "concealed family". Their HRP is George. They will be included as part of his household in relevant outputs.
