These numbers are limited to South Africa, however, they could give engineers around the world a good idea what salaries look like elsewhere in the world and could apply to the industries they are currently working in. It should give an idea of what to expect based on what engineers are making in South Africa. Or the situation could be improved elsewhere in the world, meaning engineers would be happy where they are right now and not considering travelling overseas to find better opportunities.
