General description

This dataset provides information on how often people aged 3 or older say that they speak Welsh, by local authority. These percentages sum to the total percentage who report being able to speak Welsh.

Frequency of publication

Quarterly

Data reference periods

2007 to 2021

Rounding applied

Figures are rounded to the nearest 100 and so there may be some apparent slight discrepancies between the sum of constituent items and the totals as shown.

Revisions information

Since the end of March 2020, the APS has been conducted through telephone interviews instead of face-to-face interviews as a result of the COVID-19 pandemic. The ONS has been monitoring the impact this change has had on the survey and as a result have re-weighted the estimates accordingly. More information about the reasons and methodology can be found on the ONS website (link).

The Office for National Statistics has now reweighted the Survey data to new populations derived using growth rates from HM Revenue and Customs (HMRC) Real Time Information (RTI) for January to December 2020 (i.e. quarters 1, 2, 3 and 4 of 2020) to adjust the estimates as a result of these changes. The new estimates about the ability of the population aged three or over to speak Welsh are very similar to the original estimates, varying by between 0 and 0.2 percentage points (or between -600 and 4,800) from the original estimates, at a Wales level. This varies at a local authority level and for the other Welsh language skills (including frequency of speaking Welsh).
Revised data is marked with an (r).

Statistical quality

As the data come from a survey, the results are sample-based estimates and therefore subject to differing degrees of sampling variability, i.e. the true value for any measure lies in a differing range about the estimated value. This range or sampling variability increases as the detail in the data increases, for example local authority data are subject to higher variability than regional data.
