Also...
I've made an updated chart that breaks it down into 3 classes: the BM-class Aristocracy, the NPC Aristocracy, and the Peasantry. The wealth of the BM-class aristocracy is predicated upon the "income per player" statistic and the number of nobles; it doesn't change the relative GDP per capita rankings, but it has some significant changes on the income of peasantry and aristocrats; namely, Astrum is richer overall than Madina, but Madina's peasants are richer than Astrum's. Fissoa's NPC aristocrats are slightly wealthier than Iashalur's, and, overall, a bit of the disparity between incomes of peasants went away.
I don't really know how to work tables on forums, sooo..... yeah.
