Three Common Factor That Make Local Economies Different Are:

-The Environment. There are places super fancy and places super beat down, you can't escape it that fact is everywhere.

-The Location. Locations are never the same to be honest.

All of these factors help marketers to see what they should be selling, in case of style or natural disasters known to happen in that town, city, state, etc. They also help relief come and aid when necessary. Hope this helps!
