How can goblins have higher populations than Hain if they live in a smaller area and have less mentions of them having farming? Just curious, in case I am missing something.

Rovaick do have farming (that was part of what Toun gave them) and goblins breed like rats. However, I do agree that hain should probably have a higher population, simply due to their global presence. (Goblins also have a higher mortality rate than hain, which is balanced by their excessive breeding.)
