Metadata

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 2024

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

The data item has been revised since previously published in StatsWales.

Statistical quality

These estimates were previously classed as accredited official statistics. The Annual Population Survey (APS) has seen a fall in sample sizes over recent years. Given this, and the fact that the survey has not been reweighted to latest population estimates, the Office for Statistics Regulation has agreed that this accreditation should be temporarily suspended and that the estimates should be re-designated as official statistics.

It is still appropriate to use these statistics, however, please note the increased uncertainty around estimates derived from the APS. Estimates for smaller geographies or population sub-groups, however, are less reliable.

Users should consider trends presented in this release alongside other data on Welsh speakers, such as from the National Survey for Wales. The Welsh Government considers the census of population to be the key source of information to measure the number of Welsh speakers in Wales.

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.
