Hello there,
Individual wealth is not taken into account, so it's a poor indication of prosperity in general. They are doing this to measure quality.
Hope this helps.

Maybe it means that there’s a difference between how much land they own or something. It says there was a difference between the amount of land they occupied and the amount of land they couldn’t control. So maybe they didn’t own/have a lot of land but there was a lot of land they couldn’t get to/take over etc. or maybe this situation could be vice versa so they have a ton of land but only a little isn’t “controlled” let me know if this helps sorry if it’s confusing I’m just guessing based on the context clues :)
I think the answer is the Silk Road but I'm not sure.
