A more detailed breakdown of the Gauteng economy is shown in the tables below, representing official Statistics South Africa (StatsSA) data on Gross Domestic Product for the years 1995 to the end of 2008. The data indicate that mining activity in the province has declined over the last decade and a half. By contrast, growth in secondary sectors such as construction, and tertiary sectors such as finance and business services, and transport and communication, has been robust. All three of these sectors have almost tripled in size between 1995 and the end of 2008.
