In 2002 one in seven was an entrepreneur.
"That's a huge increase. Partly it's survival, partly it's entrepreneurship. I think more and more people realise that they are not going to get rich working for someone else," he said, presenting his fifth South African unemployment report which was commissioned by trade union UASA (United Association of SA).
Most in informal sector
While there are currently an estimated 2.1m businesses in South Africa, only 600 000 were in the formal sector.
"The biggest challenge is how to bring people from the informal into the formal sector, so that they can not only pay tax but also be on a more even footing and get access to finance..." he said.
As far as workers were concerned, Schussler said the number of black men working for someone else had increased from 35% to 40% between 2002 and 2006.
All other race groups and sexes had seen a decline in the number of workers.
On education, Schussler said while 1.2m children started Grade one only 500 000 of them got to matric.
Most of these children dropped out at the end of Grade 11 and the unemployment rate in this group was 36.3%.
"Ironically, they have a higher rate of unemployment than those who didn't go any further than primary school."
