England and Wales Census 2021 - RM150: Ability to speak Welsh by national identity by age

This dataset provides Census 2021 estimates that classify usual residents in Wales aged 3 years and over in Wales by ability to speak Welsh, by national identity, and by age. The estimates are as at Census Day, 21 March 2021.

The increase since the 2011 Census in people identifying as “British” and fall in people identifying as “English” may partly reflect true changes in self-perception. It is also likely to reflect that “British” replaced “English” as the first response option listed on the questionnaire in England. Read more about this quality notice.

Estimates for single year of age between ages 90 and 100+ are less reliable than other ages. Estimation and adjustment at these ages was based on the age range 90+ rather than five-year age bands. Read more about this quality notice.

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.

Coverage

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

Welsh speaking ability

This classifies a person as being able to "Speak Welsh". They may have also ticked one or more of the following:

  • understand spoken Welsh
  • read Welsh
  • write Welsh

In results that classify people by Welsh language skills, a person may appear in more than one category depending on which combination of skills they have.

National identity

Someone’s national identity is a self-determined assessment of their own identity, it could be the country or countries where they feel they belong or think of as home. It is not dependent on ethnic group or citizenship.

Respondents could select more than one national identity.
