among other rights. Also, the Law of Linguistic Rights of the Indigenous Languages recognizes 89 indigenous languages as "national languages", which have the same validity as Spanish in all territories where they are spoken. According to the National Institute of Statistics, Geography and Data Processing (INEGI), approximately 5.4% of the population speaks an indigenous language – that is, approximately half of those identified as indigenous. The recognition of indigenous languages and the protection of indigenous cultures is granted not only to the ethnic groups indigenous to modern-day Mexican territory but also to other North American indigenous groups that migrated to Mexico from the United States in the nineteenth century and those who immigrated from Guatemala in the 1980s.
