Teotihuacan had one of the largest, or perhaps had the largest, population of any city 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 100 CE, the population could be estimated at around 60,000-80,000, after 200 years of the city's occupancy, within of the city. The population, eventually, stabilized around 100,000 people around 300 CE.
