For benchmarking purposes, How do I find out who shares the same qualification combination as me in my current location?
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.
