Some Amnian population figures, courtesy of the Lands of Intrigue sourcebook:
Total population of Amn = 3,600,000
84% human (3,024,000)
15% halfling (540,000)
1% other (36,000)
Of this 36,000, dwarves and elves are uncommon, half-orcs and half-elves are almost unheard of (although the city of Purskul has a 20% half-orc population), and gnomes are so rare that most Amnish citizens have never even met one.
Sorry to nitpick but that's not quite right.
- Of the 3,600,000 Dwarves and Elves are uncommon.
- Of the 36,000 Dwarves and Elves are the most common.
Otherwise what group makes up the majority of the 1%?
