APPENDIX 2RSGB OMNIBUS RANDOM LOCATION SAMPLING METHODA unique sampling system has been developed by TNS for its own use. Utilising UK Census small area statistics and the PostOffice Address File (PAF), GB South of the Caledonian Canal has been divided into 600 areas of equal population. From these600 areas a master sampling frame of 300 sample points has been selected to reflect the country’s geographical and socioeconomicprofile. The areas within each Standard Region were stratified into population density bands, and within band indescending order by percentage of population in socio-economic Grade’s I and II.To maximise the statistical accuracy of <strong>Omnibus</strong> sampling, sequential waves of fieldwork are allocated systematically across thesampling frame so as to ensure maximum geographical dispersion. The 300 primary sampling units are allocated to 12 subsamplesof 25 points each, with each sub-sample in itself being a representative drawing from the frame. For each wave of<strong>Omnibus</strong> fieldwork a set of sub-samples is selected so as to provide the number of sample points required (typically c. 139 for2,000 interviews). Across sequential waves of fieldwork all sub-samples are systematically worked, thereby reducing the clusteringeffects on questionnaires asked for two or more consecutive weeks.Each primary sampling unit is divided into two geographically distinct segments, each containing as far as possible, equalpopulations. The segments comprise aggregations of complete postcode sectors. Within each half (known as the A and B halves)postcode sectors have been sorted by the percentage of the population in socio-economic gro<strong>up</strong>s I and II. One postcode sectorfrom each primary sampling unit is selected for each <strong>Omnibus</strong>, alternating on successive selections between the A and B halves ofthe primary sampling unit, again to reduce clustering effects. For each wave of interviewing each interviewer is s<strong>up</strong>plied with twoblocks of 70 addresses, drawn from different parts of the sector. Addresses are contacted systematically with three doors being leftafter each successful interview.To ensure a balanced sample of adults within effective contacted addresses, a quota is set by sex (male, female housewife, femalenon-housewife); within female housewife, presence of children and working status and within men, working status.1 of 1
