. In addition to Spanish, Mexico officially recognizes 68 national languages, 63 of which are indigenous languages such as Nahuatl and Yucatec Maya

. Indigenous languages are spoken by about 6% of the population, with Nahuatl being the most widely spoken indigenous language with around 1.7 million speakers, followed by Yucatec Maya with about 850,000 speakers
