What is the population of Mexico City 2012?

The estimated total population of Mexico City in 2012 was around 8.85 million people, making it one of the most populous metropolitan areas in the Western Hemisphere. However, it's important to note that this number only includes the population within the Federal District (Ciudad de México) and does not take into account the population of the wider Mexico City metropolitan area, which includes some suburban municipalities in the neighbouring State of Mexico. When considering the entire metropolitan area, the population is significantly larger.
