I think you're right. AND a big part of it INITIALLY is the presence of natural resources. Villages - towns - cities - they all need water and food. So they start where those are available.
The weird part of TFA is how exact their numbers are.
"15 percent"
"about 83 percent"
I suspect that a LOT of averaging went on there. And more than a little bit of "toss out the 'data scatter'". Which gives them the "mathematical rule".
And what about suburbs? Do the poor people live further from the city center because they cannot afford to live there? Or do the wealthier citizens live in the suburbs because they can afford larger villas?
