Mexico is the most populous Spanish-speaking country in the world and the second most-populous country in Latin America after Portuguese-speaking [[Brazil]]. About 70% of the people live in urban areas. Many Mexicans emigrate from rural areas that lack job opportunities--such as the underdeveloped southern states and the crowded central plateau--to the industrialized urban centers and the developing areas along the U.S.-Mexico border. The Mexico City region has 18 million people and is the largest concentration of population in the Western Hemisphere. Cities bordering on the United States--such as Tijuana and Ciudad Juarez--and cities in the interior--such as [[Guadalajara]], Monterrey, and [[Puebla]]--have undergone sharp rises in population and income in recent years. | Mexico is the most populous Spanish-speaking country in the world and the second most-populous country in Latin America after Portuguese-speaking [[Brazil]].
