Abstract
The Development of a Geographical Entity for Census Data Dissemination Track: Census and Geodemographics Author(s): Nicolaas Grobbelaar Data collected during the national population census of 1996 was published at the enumerator area spatial level. This allowed all users of the data to aggregate the data based on their specific spatial entities of choice. Due to constraints regarding confidentiality, the lowest level on which the Census 2001 data was released was the second tier of the spatial hierarchy, namely, the sub place, which relates to suburbs, wards, villages, farms or informal settlements. To respond to user demand, an additional spatial layer was developed for the purpose of disseminating data for certain census variables at a level lower than the sub place and as spatially similar to the enumerator area as permitted by confidentiality. The paper will address the development of an automated spatial process to create a small area layer based on existing spatial and attribute data within Statistics South Africa's geographical hierarchy.
