  3. Benefits of mapping census data • Can be applied to data to add value, reveal patterns, support decisions • Range of types of spatial analysis from simple interpretation of a map to types that require complex software • E.g. queries, measurement, transformations and more…

  4. Serving census related geographical data products to UK academia
