Census Mapping

The 2020 Census Mapping exercise seeks to update the 2010 Census enumeration areas. This exercise is basically a geographic listing process where a frame of all housing units including vacant ones, all non-residential buildings, buildings under construction, schools, health facilities, municipal water systems, wastewater treatment facilities public transit stations, warehouses and boreholes, other structures and prominent features in an area will be compiled.
In this Mapping Census, Map Data Collectors (MDCs)/Enumerators move from one house to another and from one building to the next. The questions asked relate to the use of a building and in case of a house, occupants are asked the name of the head of a household and the number of males and females residing in a given house. Apart from houses, buildings such as shops, schools and offices are also covered.

Traditionally, census workers performed the exercise using pencil and paper and created sketch maps for use during the full population and housing enumeration. Nevertheless, the Central Statistical Office (CSO) is undergoing a digital transformation and is moving away from paper. In this regard, MDCs engaged to conduct the Mapping will be using tablets instead of paper maps.

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.
