Lima is the largest city in Peru, and the country’s capital. The seaport Callao is considered part of the city of Lima and forms the Lima Metropolitan Area. The 2014 projected population for Lima is 9,751,717, which makes Lima the fifth largest city in the Americas. Lima’s metro area is also the 27th most populous in the world.
Lima’s estimated population is 9,751,717, and these almost 10 million people live in 43 districts in Metropolitan Lima. The seaport of Callao also has six additional communities, and each of these districts have their own mayor and municipality. In addition to each district having its own Mayor, there is the Mayor of Lima who is in charge of all of the districts and municipalities. The regions are comprised of 30 districts that are within the city and 13 outer areas - which are still under the authority of the Mayor of Lima. Metropolitan Lima stretches north to south for 80 km along the Pacific Ocean, and from west to east for 40 km from the Pacific to the Andes Mountains. Since the ocean and mountains bind the city, further expansion is difficult.
The city of Lima covers a considerable amount of ground area, with 2,672.3 square kilometers (1,031.8 sq mi) available in the city itself. The population density is around 3000 people per kilometer or more than 7000 people per mile.
