A country rich in history, tradition and culture, Mexico is made up of 31 states and one federal district. It is the third largest country in Latin America and has one of the largest populations—more than 100 million—making it the home of more Spanish speakers than any other nation in the world. Despite the political and social changes that have occurred over the centuries, evidence of past cultures and events are apparent everywhere in Mexico. Many of Mexico’s rural areas are still inhabited by indigenous people whose lifestyles are quite similar to those of their ancestors. In addition, many pre-Columbian ruins still exist throughout Mexico, including the ancient city of Teotihuacán and the Mayan pyramids at Chichén Itzá and Tulum. Reminders of the colonial past are evident in the architecture of towns like Taxco and Querétaro.
