Since 2004, about 28% of South Africa’s GDP growth outturns have been above 3% in real-time (as published at the time). Revisions to GDP have tended to raise historical GDP estimates slightly, with this proportion rising to 31% in ex-post data from a fattening in the upper tail of the outturn distribution. Codera’s EconData platform makes it easy to assess data revisions and the statistical quality of data.
