England and Wales Census 2021 - RM006: Age of youngest dependent child by household type

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.

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

Dependent children in household and their age

Classifies the number of dependent children in a household, by the age of the youngest child. The age of youngest dependent children is classified as follows:

  • Aged 0 to 4 years
  • Aged 5 to 9 years
  • Aged 10 to 15 years
  • Aged 16 to 18 years

Household type

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
