England and Wales Census 2021 - RM009: Concealed family status by family type by dependent children by age of Family Reference Person

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.

Area type

Census 2021 statistics are published for a number of different geographies. These can be large, for example the whole of England, or small, for example an output area (OA), the lowest level of geography for which statistics are produced.

For higher levels of geography, more detailed statistics can be produced. When a lower level of geography is used, such as output areas (which have a minimum of 100 persons), the statistics produced have less detail. This is to protect the confidentiality of people and ensure that individuals or their characteristics cannot be identified.


Census 2021 statistics are published for the whole of England and Wales. Data are also available in these geographic types:

  • country - for example, Wales
  • region - for example, London
  • local authority - for example, Cornwall
  • health area – for example, Clinical Commissioning Group
  • statistical area - for example, MSOA or LSOA

Concealed family type

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).


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.
