Are the Mexicans more Aztec or Spanish?

Well Mexicans are a mix of Spanish and other indians not just Aztec, and because they are a mix of white and indian they are called mestizo. There are also some who have french ancestry and even some african ancestry in them, even tough most Mexicans don't think they do. Most Mexicans look a lot more indian than Spanish, but there are some that look more white. Those that look more white have more Spanish ancestry than they do indian, but most likely they still have some indian ancestry in them. So to answer your question Mexicans are a mix of both Spanish and indian and there is really no way to figure out what there are more of.
