Data on people’s ability in Welsh and how often they speak the language for April 2019 to March 2020.
This is not the latest release in the series: Welsh language data from the Annual Population Survey
The Census of Population is the key source used to measure the number of Welsh speakers in Wales. However, as the Annual Population Survey (APS) provides quarterly results, it is useful to use the APS to look at trends in the Welsh language between censuses.
- For the year ending 31 March 2020 the APS reported that 28.3% of people aged three and over were able to speak Welsh. This figure equates to 855,200 people
- This is 1.5 percentage points lower than the same quarter in the previous year (year ending 31 March 2019), equating to 41,700 fewer people.
- The chart shows how these figures have been gradually increasing each year since March 2010 (25.2%, 731,000), after they had been gradually declining from 2001 to 2007. However, the number of people reporting to be able to speak Welsh has declined each quarter from December 2018 to March 2020.
- The highest numbers of Welsh speakers continue to be found in Carmarthenshire (90,900) and Gwynedd (88,600).
- The lowest numbers of Welsh speakers are in Merthyr Tydfil (11,700) and Blaenau Gwent (11,500).
- The highest percentages of Welsh speakers can be found in Gwynedd (75%) and the Isle of Anglesey (66%).
- The lowest percentages of Welsh speakers are in Blaenau Gwent (17%) and Monmouthshire (17%).
- 16.1% (486,100) of people aged three and over reported that they spoke Welsh daily, 4.8% (144,600) weekly and 5.9% (178,300) less often. 1.5% (46,600) reported that they never spoke Welsh despite being able to speak it, with the remaining 71.7% not able to speak Welsh.
- 32.7% (987,800) reported that they could understand spoken Welsh, 25.4% (767,700) could read and 23.2% (702,500) could write Welsh.
The Census results and APS results for 2001 and 2011 have also been plotted on the chart above to indicate the large discrepancy between the two sources at the same time periods. There are a number of possible explanations for why Census results would be lower than survey results. For example, the Census is a statutory self-completion questionnaire, the APS is a voluntary survey, which uses face-to-face interviews.
The APS results should not be compared against Census results, nor used to measure progress towards the Welsh Government target of a million Welsh speakers by 2050. The Welsh language strategy Cymraeg 2050, clearly states that this target was based on census data and that progress towards this target will be monitored using future census data.
A blog published by the Chief Statistician last year, gave a brief discussion on how to interpret the Welsh language data in the APS. More information about the differences between the APS and the Census can be found in a bulletin presenting more detailed results on the Welsh language from the APS from 2001 to 2018.
The APS is carried out by the Office for National Statistics (ONS). Details about how the survey is developed and carried out can be found on the Office for National Statistics website.
Following the government advice regarding coronavirus (COVID-19), the Annual Population Survey as well as all other ONS face-to-face studies about people, families and households have been suspended. From mid-March 2020, the APS survey has been carried out by telephone. A change in how a survey is administered can affect survey results. This set of results cover the period from April 2019 to March 2020, and therefore the results are unlikely to be significantly affected. There may however be some disruption to the APS time series for the next quarter’s results, which may affect the timing, availability and/or quality of data for the first half of 2020-21.
