Provides the basis from which to strategically monitor and track trends in sport in Wales, as well as forming a base from which to shape policy and practice. The Active Adults Survey is a large scale survey of the adult population in Wales using CAPI. Adults (defined as aged 15 and above) living in private households in Wales were eligible to take part in the survey. The survey is done face to face, with an interviewer visiting the person at their home. Households are selected at random, and the interviewer randomly selects someone from the household to take part in the survey, when they visit.
