Interpreting News Stories

[Shiv Jey]

I've been reading the news daily on the country's biggest employers to track where they are expanding to.  If company X builds a warehouse and expects to hire 50k people in Y city, how do you approach this information?  Does this typically indicate growth with such a large plan for expansion, or does it simply move people around in the current city and not affect growth reliably?  Thoughts on the matter?
