What percent of Mexico's population is of mixed Spanish and indigenous heritage?

It is about 60%. 30% is all or mostly Aztec or of another indigenous ancestry. 9% are the Criollo descendants of Spaniards or other European descendants. And 1% are other mostly composing of Lebanese.

I heard that its about 95 percent. 3 percent is pure latin white people and 2 percent is mixed with black.

Upwards of 90%
