LocationNational Survey for Wales, 2018-2019
UniverseThe National Survey for Wales involves a 45 minute interview with a randomly-selected sample of people aged 16 and over living across Wales. The survey is conducted annually spread over a whole year starting from the beginning of April and ending with end of March the following calendar year, and runs all year round. Each year, a sample of addresses is selected at random from the Royal Mail’s list of addresses. Survey interviews then take place face-to-face (with a small self-completion element for the most sensitive questions), in-home with one randomly-selected adult in each selected household. No replacement of addresses or individuals is allowed. The achieved sample size is over 11,000 respondents each year. The sample in each local authority is broadly in proportion to local authority population size. The results are weighted to be representative of the adult population in Wales. Fieldwork for the National Survey for Wales is carried out by the Office for National Statistics.
