City Analysis

The current population of Mexico City is 8.85 million. Mexico city is not part of any of the 31 states in Mexico, but is considered a federal entity. This federal entity would be a National Metropolis on the hierarchy of Central Places. There are two large regional cities around Mexico City that contain just over one million people in each: Ecatepec de Morelos (1.6 million) and Nezahualcóyotl (1.11 million). Melchor Ocampo (50,000 people) and Tepotzotlán (88,000 people) are towns around Mexico City. The map shown below, from www.citypopulation.de, is of cities and towns indicated by population. The larger and more pink the symbol is (and if it has a black dot) the more populated the location.

Mexico City is home to 21% of the entire country's GDP. Many of the higher income jobs may be found in Mexico City and larger surround areas than in the towns like Melchor Ocampo. Since Mexico City is largest in the entire country of Mexico (and also the largest in North America), there is not much that can't be found. It may be difficult for people to buy freshly picked crops like those in smaller areas, though it is common to see street vendors.
