An occupancy survey has been continuously undertaken amongst graded hotel accommodation providers since 1972 to monitor levels of demand for hotel rooms and beds in Wales. To comply with the requirements of the EU Directive on Tourism Statistics, the survey was extended in 1997 to include all serviced accommodation including guest houses and bed and breakfast establishments, as well as non‐graded serviced accommodation.
The self catering survey has been conducted in varying formats since 1987. Since 2003 however, the methodology and software used to analyse the data has been consistent. The survey covers self catering accommodation, caravan holiday homes, touring caravan and camping parks. In addition, in 2008, hostels and bunk houses were also included within the coverage of the survey.
