15 million is a reasonable mid range estimate for Mesoamerica alone, and a decent amount of estimates give it 20 million or more, and OP's pic includes not just Mesoamerica, but the rest of Mexico, all of Central America, and the US, Canada, and the West Indies. The AI response here is laughably wrong

For reference, here are the estimates from "The Native Population of the Americas in 1492" by Denevan, the 1976 column it the First Edition print, the 1992 is the Second Edition print. Going by the 2nd edition numbers, what OP pics shows would have had around 29.6 million people

The ~212,000 population estimate people often give for Tenochtitlan is based on agricultural production and what it could support.

I know >plebbit but all the different comments by 400-rabbits here are a good overview of a bunch of different population estimates for Tenochtitlan: https://www.reddit.com/r/AskHistorians/comments/1dp8dfn/was_tenochtitlans_population_really_as_big_as/
