The city is practically coextensive with the municipality. The census of 2005 reported a population of 524,223 for the city and 525,389 for the municipality as a whole.[3]
Chimalhuacán was founded 1259 by three chiefs or tlatoani named Huauxomatl, Chalchiutlatonac and Tlatzcantecuhtli. These chiefs and their people originated from Tula and Culhuacán. They spoke Chichimeca and Mexica languages but with time their customs merged and Náhuatl became the dominant language. It became subject to Texcoco, and through that belonged to the Aztec Triple Alliance in 1431. The Spanish town of Chimalhuacán was founded in 1529 and the Dominicans built a church and monastery here in 1563.[3]
The municipality
Although the city takes up almost all of the municipality, Chimalhuacán, as the municipal seat, has governing jurisdiction over the following communities: Colonia Nueva de Guadalupe la Palma, La Pista de los Corredores, Pista Aérea, Tlatel San Juan Xochiaca Parte Alta, and Zapotla.
Chimalhuacan has a new park in the center of the municipality, Plaza Estado de Mexico Chimalhuacan, with a library, theater and other places for entertainment.
The entry of the municipality has a monument to Chimalhucán, called Guerrero Chimalli, a 60-meter tall steel statue.
During September 2015, a series of attacks on the citizens of Chimalhuacan began. The attacker was nicknamed "La Degolladora" ("The Throat-Slitter", "The Slasher") by local and international press due to the use of knives to injure and kill people randomly.[4]

Six members of the ″Loca Tristeza Mexicana″ band were arrested in March 2021 for two murders in 2020. Band members were heavily armed and in possession of drugs. They were also implicated in a kidnapping and murder of a local firefighter in 2018.[5]
