It is difficult to conclusively determine the size of South Africa's informal sector, though it contributes a great deal to the economy.
Dr Tashmia Ismail, market expert at the Gordon Institute of Business Science (GIBS), says that there is no consensus on the estimated statistics of the sector.
There are a lot of numbers. There are three wildly different numbers around the size of it. StatSA talks about 120 billion, UCT Unilever Institute is over double that and there's an Adcorp number which seems rather inflated.— Dr Tashmia Ismail, Head of the Inclusive Markets Programme at GIBS
She says researchers are cautious about figures in the informal sector, as the nature of the business suggests that it cannot be properly measured.
Ismail explains that the informal sector moves money in spaces that cannot be calculated because the sector is a cash economy.
It's not flowing through the financial services system, so we've got to be a little wary.— Dr Tashmia Ismail, Head of the Inclusive Markets Programme at GIBS
She says the informal sector thrives most in township spaces, where unemployment is the highest.
