HOW TO FIGURE OUT WHO EMPLOYS MOST OF MARKET

[Jason Malabute]

Hey guys,

I feel like I have a general understanding of largest employers in my prospective markets, but I think what I am truly looking for is WHO EMPLOYS A MAJORITY OF MY MARKET AND KEEPS ECONOMY GOING?

For example, if I am considering about investing in suburb "A" who's largest employer is a grocery store, but in reality most of residents in that town commute to City "B" that is only 2 miles away which has a major university and hospital.

How would I research and figure this out?
