Lower customer density probably also correlates with harder to get to.

If your local farmers market is convenient to get to, maybe you go there for small orders, and if it's convenient for you, it's likely convenient for many. If your local market is hard to get to, you probably don't go as often, but when you do, you get more stuff.

If the market is near dense residential, it probably gets more customer density and more small orders; if it's out in the sticks, it probably gets less customer density and larger orders. You're not driving 30 minutes round trip to get one pepper that you need right now, but you might walk a 5 minute round trip for that.
