The National Survey for Wales is a large-scale, random sample household survey of adults (ages 16-years and above) across Wales. This survey is implemented by Welsh Government on behalf of public bodies in Wales.
Due to methodological changes to the 2021-22 survey, comparisons between 2021-22 figures and figures from previous iterations of the survey should be limited and treated with discretion.
For more information on methodology, please refer to the Introduction.
