Oaxaca is one of the 31 states which, along with the Federal District, comprise the 32 federative entities of Mexico. It is divided into 571 municipalities; of which 418 (almost three quarters) are governed by the system of customs and traditions. Its capital city is Oaxaca de Juárez. The state is best known for its indigenous peoples and cultures. The most numerous and best known are the Zapotecs and the Mixtecs, but there are sixteen that are officially recognized. These cultures have survived better to the present than most others in Mexico due to the state’s rugged and isolating terrain. Most live in the Central Valleys region, which is also an important area for tourism, attracting people for its archeological sites such as Monte Albán, native culture and crafts. Another important tourist area is the coast, which has the major resort of Huatulco. The state also has some of the greatest biodiversity in Mexico.
