Mexico is the fifth largest country in the Americas, covering almost 2 million square kilometers with a population of 111 million people. It is comprised of 31 states and a federal district containing the capital city. While Spanish is the official language, many indigenous languages are still spoken. The majority of Mexicans are Roman Catholic, with one of the highest rates of church attendance in the world. Popular sports include soccer and bullfighting, and music genres vary regionally but include corridos, polka, and banda. Traditional dances showcase Mexico's cultural diversity, and typical foods go beyond tacos to include dishes like ceviche and chicken pibil. The Aztecs founded what is now Mexico City over 700 years ago.
