After all, elsewhere in the Americas, it's known that the death rate among native Americans was ordinarily over 90% for smallpox.

Wasn't that very highly dependent upon family structure too?

There were a wide variety of "family" structures among the Indians along the East Coast of what is now the United States back in the 1640s when over 90% of them died of disease.

It's actually pretty easy to find references based on secondary sources to a 95% death rate.

I think the problem isn't with the death rate, it's with the estimates of how many people lived in Mexico and how many died.

Whatever it was, the death rate was sufficient to destroy society and actually bring down Earth's mean temperature because of the loss of agriculture and the methane that goes with it.
