Lima is the capital and the largest city of Peru. It is located in the valleys of the Chillón, Rímac and Lurín rivers, in the central coastal part of the country, overlooking the Pacific Ocean. Together with the seaport of Callao, it forms a contiguous urban area known as the Lima Metropolitan Area. With a population of more than 10 million, Lima is the most populous metropolitan area of Peru and the third-largest city in the Americas (as defined by "city proper"), behind São Paulo, and Mexico City. The metropolitan area around Lima has a population of more than 12 million.
Lima is the country's industrial and financial centre and one of Latin America's most important financial centers, home to many national companies and hotels. It accounts for more than two thirds of Peru's industrial production and most of its tertiary sector. Products include textiles, clothing and food. Chemicals, fish, leather and oil derivatives are manufactured and/or processed. The financial district is in San Isidro, while much of the industrial activity takes place west of downtown, extending to the airport in Callao. Lima has the largest export industry in South America and is a regional hub for the cargo industry. The Callao seaport is one of the main fishing and commerce ports in South America
