Census Mapping

When the information is captured and synchronized via internet to a central database, an electronic inventory list of structures and their use is compiled. This forms the database of an updated list of structures (the Geospatial database), which is sub-divided into workloads called Enumeration Areas. A digital Enumeration Area Map is developed with identifiable boundaries and updated information on structures and other prominent features. This exercise makes the work of Population and Housing Enumeration easier when it begins a few months later. This is because the Enumerator knows how many houses he or she has to cover and where they are located.

The objectives of census mapping are;

  • To compile a frame or list of all Housing Units and other structures within an enumeration area;
  • To determine the size of the enumeration area (number of, households and persons);
  • To enable enumerators during census to find their way within the enumeration area more easily, so that they can actually visit all Housing Units in their enumeration area
  • To identify all residential and non-residential structures including unoccupied, vacant and new housing units under construction;
  • To use the gathered information to update the base maps and the geo-spatial database;
  • To ensure that enumerators have a uniform work load in terms of households to cover during enumeration. Urban enumeration areas will range from 150-200 while rural areas will have 80-120 households; and
  • To provide the basis to estimate resources required at each administrative level e.g. personnel, materials and transport.
