Accessibility of supermarkets in London (within 1 km), 1961–2005. Source: Statictics Canada, 1961, 2001; Vernon's City Directory, 1961, 2005. Census tracts within the City of London are shaded to indicate urban versus suburban neighbourhoods for 2005 and the City of London for 1961. The locations of supermarkets in London are indicated as points, and are surrounded by 'service areas' that represent areas that are accessible within 1000 metres from a given supermarket along the street network.
