Welsh Health Survey
The Welsh Health Survey (WHS) collects information about the health of people living in Wales, the way they use health services, and the factors that can affect their health. The current WHS series was conducted for the first time in 2003-2004. It is commissioned by the Welsh Assembly Government (WAG), and carried out by the National Centre for Social Research. The new WHS replaces two previous study series: the previous WHS, conducted in 1995 and 1998, and the Health in Wales Survey which was conducted five times in 1985, 1988, 1990, 1993 and 1996. Users should note that results from the new WHS survey are not comparable with those from the previous surveys, because of differences in the questionnaires and survey methodology.
In 2003, the survey methodology changed substantially and it became a continuous survey. The current survey involves an interview to collect household data from one member of the household, followed by a self-completion questionnaire from each household member (a parent completes the questionnaire on behalf of young children). The achieved sample size is around 15,000 adults and 3,000 children each year.
