What mean location wise?

(A general area); So if I told, a friend, that I was thinking about moving, and they wanted to know where, they might ask me....

"So where are you thinking about moving to, location wise?"

(My Response): "Southern California, maybe Los Angeles."

'Location wise' means as per each location.

It may be the applicability of something against each specific locations. i.e. The location wise stock, location wise population, location wise poverty, etc...
