The Welsh Language Commissioner undertakes research into many different aspects of the Welsh language in order to:
  • support our work in influencing policy
  • produce policy notes and respond to consultations in a meaningful way
  • produce assurance reports that show how organisations are performing and reports on the user experience
  • produce resources to assist and encourage organisations, charities and businesses of all kinds to use the Welsh language
  • produce a statutory report every 5 years on the position of the Welsh language.
This research is mainly done by collecting data from organisations, conducting focus groups, conducting surveys and through desktop research. A collection of our latest research reports can be seen on the right hand side of the page.
Statistics on the number of speakers and use of Welsh
The census is the main authoritative source for information on the numbers of Welsh speakers in Wales.
Statistics on the use of the Welsh language can be found in the results of the Welsh Language Use Survey that we conducted jointly with the Welsh Government and published in 2015. The results of the next Welsh Language Use Survey will be published by the Welsh Government in 2021.
The Welsh Government also collects statistical information on the Welsh language and useful analysis based on annual national surveys on the StatsWales website. There is also a section that brings together other data sources on the Welsh language and links to useful external websites such as InfoBaseCymru which is maintained by Data Cymru.
Official Statistics
The Welsh Language Commissioner was named as an Official Statistics producer in April 2013.
When producing official statistics, we will act in accordance with the principles set within the UK Statistics Authority Code of Practice for Official Statistics.
Further information on Official Statistics, the Code of Practice and the UK Statistics Authority can be found here.
