spoken in rural areas by an impoverished class of indigenous subsistence agriculturists. According to the Mexican national statistics institute, INEGI, 51% of Nahuatl speakers are involved in the farming sector and 6 in 10 receive no wages or less than the minimum wage. From the early 20th century to at least the mid-1980s, educational policies in Mexico focused on the Hispanicization () of indigenous communities, teaching only Spanish and discouraging the use of indigenous languages. As a result, today there is no group of Nahuatl speakers having attained general literacy in Nahuatl, while their literacy rate in Spanish also remains much lower than the national average. Even so, Nahuatl is still spoken by well over a million people, of whom around 10% are monolingual. The survival of Nahuatl as a whole is not imminently endangered, but the survival of certain dialects is, and some dialects have already become extinct within the last few decades of the 20th century. The 1990s saw the onset of a radical change in official Mexican government policies towards indigenous and linguistic rights. Developments of accords in the international rights arena combined with domestic pressures (such as social and political agitation by the Zapatista Army of National Liberation and indigenous social movements) led to legislative reforms and the creation of decentralized government agencies like the National Commission for the Development of Indigenous Peoples (CDI) and the Instituto Nacional de Lenguas Indígenas (INALI) with responsibilities for the promotion and protection of indigenous communities and languages. In particular, the federal Ley General de Derechos Lingüísticos de los Pueblos Indígenas ['General Law on the Language Rights of the Indigenous Peoples', promulgated 13 March 2003] recognizes all the country's indigenous languages, including Nahuatl, as national languages and gives indigenous people the right to use them in all spheres of public and private life. In Article 11, it grants access to compulsory, bilingual and intercultural education. Nonetheless, progress towards institutionalizing Nahuatl and securing linguistic rights for its speakers has been slow. Demography and distribution Today, a spectrum of Nahuan languages are spoken in scattered areas stretching from the northern state of Durango to Tabasco in the southeast. Pipil, the southernmost Nahuan language, is spoken in El Salvador by a small number of speakers. According to IRIN-International, the Nawat Language Recovery Initiative project, there are no reliable figures for the contemporary numbers of speakers of Pipil. Numbers may range anywhere from "perhaps
