What is a general description of Mexico city?

Answer 1

Mexico is so extensive with varying climates, geography and city layouts that the only general description would be that most cities have a central plaza or zocalo, around which you can find a church or cathedral as well as most of the government buildings. Layout is square for most of the downtown, while more modern parts of the city follow an organic pattern; cities with enough size and income can afford to have better infrastructure such as freeways, subways or other large-scale public transportation.

Answer 2

It is the political, cultural and economic capital of Mexico. One of the largest cities in the world in terms of population, it is inhabited by more than 21 million people (2012), highly-concentrated in an area roughly half the size of New York City. It is also a city with high contrasts, as you can find tall skyscrapers and huge McMansions not too far from decaying slums.
