    Abstract

    This study set out to investigate the patterns of deprivation between Tesco and Waitrose supermarket catchment areas. Deprivation data came in the form of raw numbers from the 2001 Census of Population, this was manipulated into a dataset. The further analysis was carried out in MapInfo Professional 8.0 GIS software, boundary data was downloaded from Edina UKBORDERS. Voronoi (theissen) polygons were created to represent the store catchment areas. The deprivation data was at ST wards level, so was intersected with the catchment areas. The results were mapped in the form of normal scores. The maps showed that Waitrose had more catchment areas in deprived areas but Tesco had the highest individual deprivation scores. A positive relationship was found between population density and average Nscore. Also as population density increased the size of the catchments got smaller. Geodemographics and deprivation are discussed in some detail and a conclusion is reached that deprivation data alone is not enough to fully describe and examine store catchment areas. Also there are much more advanced spatial models available for defining store catchment areas.
