I would start by saying that the information on the industry is scarce. The NOCs haven't been updated in ages, the national classification system for occupation. It's very hard for me to tell you, for example, how many engineers there are, and all the positions. Since they haven't been updated, it's very hard to track the labour pool right now. It's even harder to track that labour pool based on where they were before.
