    Waitrose has long been regarded as a supermarket that attracts or targets the upper classes of population classifications. This study sets out to investigate the relationship between Waitrose store catchments and the affluence of their population based on an 'Affluence Index'. The lack of literature concerning Waitrose or studies of affluence was accepted and was seen as adding to the importance of this study. In the process, a GIS was constructed in MapInfo (and partly in ArcMap), which could be queried in order to output various maps and tables to illustrate trends in the data. Thiessen polygons were created around geocoded store points and then clipped to the England coastline in its entirety to define the store catchments by area. In addition, ward boundaries were assigned the affluence data, as well as other statistics including population. The thiessen polygons were then overlaid on to the wards (as an aerial weighting) in order to extract this data, however the computing power of MapInfo was not sufficient and therefore ArcMap was used. This meant each catchment and store had a series of affluence indices assigned to it. Furthermore, population density figures were calculated and the variables were given a weighting based on their significance on the average NSCORE. Maps of the most affluent catchment ranges could then be produced and more specific sites where Waitrose stores could be located were mapped. In summary, it was found that there are still potential sites in England for Waitrose to locate their stores, both in densely populated urban areas and sparsely populated rural areas. It is concluded that the potential for further study is excellent with very few studies focussing on the affluence of catchments or on Waitrose. It also recognises the importance of constructing a fuller affluence index and including other variables if freer access to the Waitrose information was granted. All in all, it is a study that makes good headway in an area that is relatively untouched by other literary work.
