Far fewer people realize that, in addition to Spanish, another 62 indigenous languages are also spoken in Mexico. According to the recent census, about 11 million Mexicans are "indigenous". However, about 4 million of the indigenous population no longer speak their native tribal language. The 62 living indigenous languages still in use in Mexico make the country one of the most liguistically diverse in the world, in terms of the number of languages spoken, behind Papua New Guinea, Indonesia and India but well ahead of China, Brazil and just about anywhere else. The largest indigenous groups (with their approximate numbers in 1997 in parentheses) are those speaking Nahuatl (2,563,000), Maya (1,490,000), Zapotec (785,000) and Mixtec (764,000), followed by those using Otomí (566,000), Tzeltal (547,000) and Tzotzil (514,000). Other well known groups include the 204,000 having Purépecha (or Tarasco) as their first language and the 122,000 speaking Tarahumara.
