However, Chiapas remains one of the poorest states in Mexico. Ninety-four of its 111 municipalities have a large percentage of the population living in poverty. In areas such as Ocosingo, Altamirano and Las Margaritas, the towns where the Zapatistas first came into prominence in 1994, 48% of the adults were illiterate. Chiapas is still considered isolated and distant from the rest of Mexico, both culturally and geographically. It has significantly underdeveloped infrastructure compared to the rest of the country, and its significant indigenous population with isolationist tendencies keep the state distinct culturally. Cultural stratification, neglect and lack of investment by the Mexican federal government has exacerbated this problem.
