Examining the economy-wide consequences of South Africa following a similar trajectory of labour market polarization to the rest of the world requires an appropriate database for an economy-wide policy analysis framework. This paper describes how a 2015 South Africa social accounting matrix (SAM) was updated for 2016 and expanded to include labour market disaggregation by occupation and some capital market disaggregation. This extended SAM will provide a basis for the construction of an economy-wide modelling framework to examine the implications of likely future growth and structural and technological changes for skills demand in South Africa.
