With the help of trained engineers, builders, and traders, the Aztec capital city of Tenochtitlan became a great city. It had huge temples, beautiful open plazas, and a huge bustling central marketplace. By the mid-1400’s, Tenochtitlan had a population of about 300,000 people, which made it the largest city in the world at that time!
No one used money. Goods were bartered and small differences in value were evened up using cocoa beans!
Government was a kingdom.
All that is left are small pockets of water, and underground waterways.
Today, with over 8,836,045 inhabitants in 2008. Mexico City is also the Federal District (Distrito Federal in Spanish). Mexico City is one of the most important economic hubs in Latin America. The city proper (Federal District) produces 21.8% of the country's gross domestic product.
Mexico City is served by the Sistema de Transporte Colectivo Metro, an extensive metro system (207 km), which is the largest in Latin America.
The city government also operates a network of large buses, in contrast with the privately operated microbuses, with fares barely exceeding that of the metro. Electric transport other than the metro also exists, in the form of trolleybuses and the Xochimilco Light Rail line. Mexico City is served by Mexico City International Airport (IATA Airport Code: MEX).
