Although most indigenous language speakers are bilingual, especially in the younger generations, many of these languages have shown resilience. 4 of Chiapas' indigenous languages Tzeltal, Tzotzil, Tojolabal and Chol are high-vitality languages, meaning that a high percentage of these ethnicities speak the language and that there is a high rate of monolingualism in it. It is used in over 80% of homes. Zoque is considered to be of medium-vitality with a rate of bilingualism of over 70% and home use somewhere between 65% and 80%. Maya is considered to be of low-vitality with almost all of its speakers bilingual with Spanish. The most spoken indigenous languages as of 2010 are Tzeltal with 461,236 speakers, Tzotzil with 417,462, Ch’ol with 191,947 and Zoque with 53,839. In total, there are 1,141,499 who speak an indigenous language or 27% of the total population. Of these 14% do not speak Spanish. Studies done between 1930 and 2000 have indicated that Spanish is not dramatically displacing these languages. In raw number, speakers of these languages are increasing, especially among groups with a long history of resistance to Spanish/Mexican domination. Language maintenance has been strongest in areas related to where the Zapatista uprising took place such as the municipalities of Altamirano, Chamula, Chanal, Larráinzar, Las Margaritas, Ocosingo, Palenque, Sabanilla, San Cristóbal de Las Casas and Simojovel.
