For benchmarking purposes, How do I find out who shares the same qualification combination as me in my current location? How do I acquire the stats on how many people in my state/province/country share the same academic qualifications as me? I'm completing a MTech-Marketing and CIMA combination and live in Durban, South Africa. Information on who they are and current positions would also be advantageous.

For benchmarking and job-hunting purposes, the information I'm looking for should read like this- There are 3 people currently working in the Durban area who have a Masters in Marketing + CIMA combination. They are employed by company A, B an C and occupy positions X, Y and Z.
This type of information is not generally systematically tracked, at least not by most current governments or academic organizations.  At a coarse-grained level, you may be able to find out some information from censuses (e.g., these US census tables), but not to a degree of detail necessary for the type of analysis of the competitive landscape that you seem to be looking for.
