Teotichuacan was one of, or was, the largest population in the Basin of Mexico during its occupation.
Teotihuacan was a large pre-historic city that underwent massive population growth and sustained it over most of the city's occupancy.
In the 100 AD the population could be estimated around 60,000-80,000, after 200 years of the city's occupancy, within 20 km² of the city.
The population, eventually, stabilized around 100,000 people around 300 BCE.

The population reached its peak numbers around 400 to 500 AD.
During 400 to 500 AD, the Xolalpan period, the city’s population was estimated to be 100,000 to 200,000 people.
This number was achieved by estimating compound sizes to hold approximately 60 to 100, with 2,000 compounds.
These high numbers continued until the city started to decline between 600 and 700 AD.

One of Teotichuacan’s neighborhood, Teopancazco, was occupied during most of the time Teotichuacan was as well.
It showed that Teotichuacan was a multiethnic city that was broken up into areas of different ethnicities and workers.
This neighborhood was important in two ways; the high infant mortality rate and role of the different ethnicities.
The high infant mortality rate was important within the neighborhood, and the city at large, as there are a large number of perinatal skeletons at Teopancazco.
This suggests that the population of Teotihuacan was sustained and grew due to people coming into the city, rather than the population reproducing.
The influx of people came from surrounding areas, bringing different ethnicities to the city.
