Planning for Census 2021 has commenced and this creates an opportunity to evaluate and redesign the output geographies if needed. Statistics South Africa is researching the creation of a specific designed output (spatial) layer to disseminate the Census 2021 data. Since a census is expensive, such a layer ought to be such that it is useful to as wide an audience as possible: especially to governmental departments, municipalities, various planners and researchers, private businesses, NGOs, etc., to support better planning and decision-making.

The current Small Areas (SAs) layer is the lowest level in the geographic hierarchy for which census data is available. The enumeration areas (EAs) were used in the creation of these small areas since the census questionnaires were geocoded to the EA and not to individual addresses or locality coordinates. The EA specifications are such that they enable the execution of the census, in other words: it is an operational layer – it is not designed for dissemination.

The aim with this presentation is to look at some design elements that have been used by the United Kingdom, Australia, New Zealand and Canada for their output areas and to initiate a conversation on how the characteristics of ideal output areas for South Africa should look like.
