What can you tell me about the different indigenous people of Mexico?

Do you mean currently or like Aztecs in the past? I live on the border of Mexico and I see homeless indigenous women and children begging or selling candy on the streets all the time. What I have never seen is a indigenous man so I have no idea how these women get pregnant. It's not like in the U.S where the native Americans have been Americanised. They still wear clothes that they make themselves and they carry babies in those sling type things. There is a group called Tauramara they have a language but they also speak Spanish. It's rumored that their rich because they make women beg on the streets. This is in the north of Mexico by the way. That's all I know.
