Abstract
English: Migration is critical for policy agendas and government planning as it changes the
demographic composition of towns, cities and regions – this requires adjustments to
service and infrastructure provision. To develop suitable policy responses, reliable,
comparable and timely information is required. Obvious sources of migration data are
the national census and household and labour surveys. Socio-economic data have
not dealt well with migration. A recent CSIR research project, Spatial and Temporal
Evidence for Planning in South Africa1 (StepSA), explored the use of voter registration
information as an alternative source of migration data. Anonymised voter registration
data were provided by the Independent Electoral Commission of South Africa for
several consecutive elections covering a 12-year period. The data, once spatialised
(and related to a single set of voting districts), could then be processed to extract
movement trends between different election periods. This article describes the process
applied and the initial analyses conducted.
Afrikaans: Migrasie is krities belangrik vir beleidsformulering en ruimtelike beplanning gegewe die demografiese samestelling van dorpe en stede wat daardeur geraak word. Bykomend beïnvloed dit ook infrastruktuur- en diensteverskaffing. Die bekendste bron van sodanige inligting is Statistieke Suid-Afrika wat migrasiedata publiseer wat versamel is deur die tien-jaarlikse sensus asook deur die arbeid- en gesinsopnames. Sosioekonomise data bevat in die algemeen nie veel migrasiedata nie. ’n Onlangse projek genaamd “Spatial and Temporal Evidence for Planning in South Africa2 (StepSA)” het die moontlikheid verken om kiesersregistrasiedata as ’n alternatiewe bron van migrasiedata te benut. Geanonimiseerde kiesersdata is verskaf deur die Onafhanklike Verkiesingskommissie (OVK) van Suid-Afrika vir verskeie verkiesings wat oor ’n periode van 12 jaar gestrek het. Die data is ruimtelik verwerk en geprosesseer om die bewegings van persone tussen verskillende verkiesings te onttrek. Hierdie artikel beskryf die proses kortliks en ook die aanvanklike bevindinge.
