Greater Mexico City in the context of "Chapultepec"

Mexico City is the capital and largest city of Mexico, as well as the most populous city in North America. It is one of the most important cultural and financial centers in the world, and is classified as an Alpha world city according to the Globalization and World Cities Research Network (GaWC) 2024 ranking. Mexico City is located in the Valley of Mexico within the high Mexican central plateau, at an altitude of 2,240 meters (7,350 ft). The city has 16 boroughs or demarcaciones territoriales, which are in turn divided into neighborhoods or colonias.

The 2020 population for the city proper was 9,209,944, with a land area of 1,495 square kilometers (577 sq mi), making it the second largest Spanish-speaking city proper in the world. According to the most recent definition agreed upon by the federal and state governments, the population of Greater Mexico City is 21,804,515, which makes it the world's sixth-largest metropolitan area and the second-largest urban agglomeration in the Western Hemisphere (behind São Paulo, Brazil). Greater Mexico City has a GDP of $411 billion in 2011, which makes it one of the most productive urban areas in the world. The city was responsible for generating 15.8% of Mexico's GDP, and the metropolitan area accounted for about 22% of the country's GDP. If it were an independent country in 2013, Mexico City would be the fifth-largest economy in Latin America.

The Bajío (the Lowlands) is a cultural and geographical region within the central Mexican plateau which roughly spans from northwest of Mexico City to the main silver mines in the northern-central part of the country. This includes (from south to north) the states of Querétaro, Guanajuato, parts of Jalisco (Centro, Los Altos de Jalisco), Aguascalientes and parts of Zacatecas, San Luis Potosí and Michoacán.

Located at the border between Mesoamerica and Aridoamerica, El Bajío saw relatively few permanent settlements and big civilizations during Pre-Columbian history, being mostly inhabited by the Otomi and semi-nomadic tribes known to the Aztecs as the "Chichimeca" peoples (poorly attested conglomerate of Uto-Nahua groups, from whom the Toltec and the Aztecs were probably descended). The tribes that inhabited the Bajío proved to be some of the hardest to conquer for the Spanish—peace was ultimately achieved via truce and negotiation—but due to its strategic location in the Silver Route, it also drew prominent attention from Europe, and some of the flagship Mexican colonial cities were built there, such as Zacatecas and Guanajuato. Abundant mineral wealth and favorable farming conditions would soon turn the region into the wealthiest of New Spain. At the beginning of the 19th century, El Bajío was also the place of the ignition of the Mexican War of Independence, and saw most of its battles during the initial phase of the war, including the Cry of Dolores, the storming of the Alhóndiga de Granaditas and the Battle of Calderón Bridge.

The Valley of Mexico (Spanish: Valle de México; Nahuatl languages: Anahuac, lit. 'Land Between the Waters'), sometimes also called Basin of Mexico, is a highlands plateau in central Mexico. Surrounded by mountains and volcanoes, the Valley of Mexico was a centre for several pre-Columbian civilizations including Teotihuacan, the Toltec, and the Aztec Empire. The valley used to contain five interconnected lakes called Lake Zumpango, Lake Xaltocan (Nahuatl languages: Xāltocān), Lake Xochimilco, Lake Chalco and the largest, Lake Texcoco, covering about 1,500 square kilometers (580 sq mi) of the valley floor. When the Spaniards arrived in the Valley of Mexico, it had one of the highest population concentrations in the world with about one million people. After the conquest of the Aztec Empire, the Spaniards rebuilt the largest and most dominant city, Mēxihco Tenōchtitlan, renaming it Ciudad de México (Mexico City) and over time began to drain the lakes' waters to control flooding.

The Valley of Mexico is located in the Trans-Mexican Volcanic Belt. The valley contains most of the Mexico City metropolitan area, as well as parts of the State of Mexico, Hidalgo, Tlaxcala, and Puebla. The Basin of Mexico covers approximately 9,600 km (3,700 sq mi) in the NNE-SSW direction with length to width dimensions of approximately 125 km (78 miles) to 75 km (47 miles) The Valley of Mexico can be subdivided into four basins, but the largest and most-studied is the area that contains Mexico City. This section of the valley in particular is colloquially referred to as the "Valley of Mexico".The valley has a minimum elevation of 2,200 meters (7,200 ft) above sea level and is surrounded by mountains and volcanoes that reach elevations of over 5,000 meters (16,000 ft). It is an enclosed valley with no natural outlet for water to flow to the sea although there is a gap to the north where there is a high mesa but no high mountain peaks. Within this vulnerable watershed all the native fishes were extinct by the end of the 20th century. Hydrologically, the valley has three features. The first feature is the lakebeds of five now-extinct lakes, which are located in the southernmost and largest of the four sub-basins. The other two features are piedmont, and the mountainsides that collect the precipitation that eventually flows to the lake area. These last two are found in all four of the sub-basins of the valley. Today, the Valley drains through a series of artificial canals to the Tula River, and eventually the Páruco River and the Gulf of Mexico. Seismic activity is frequent here, and the valley is an earthquake-prone zone.

Monterrey (MON-tə-RAY; Spanish: [monteˈrej] ) is the capital and largest city of the northeastern Mexican state of Nuevo León. The city anchors the Monterrey metropolitan area, the second-largest metropolitan area in Mexico, after Greater Mexico City with a population of 5,341,171 people as of 2020 and it is also the second-most productive metropolitan area in Mexico with a GDP (PPP) of US$140 billion in 2015. According to the 2020 census, Monterrey itself has a population of 1,142,194.Located at the foothills of the Sierra Madre Oriental, Monterrey is a major business and industrial hub in Mexico and Latin America.

Monterrey is considered one of the most livable cities in Mexico, and a 2018 study ranked the suburb of San Pedro Garza García as the city with the best quality of life in the country. It serves as a commercial center of northern Mexico and is the base of many significant international corporations. Its purchasing power parity-adjusted GDP per capita is considerably higher than the rest of Mexico's at around US$35,500, compared to the country's US$18,800. It is considered a Beta World City, cosmopolitan and competitive. Rich in history and culture, it is one of the most developed cities in Mexico.

The Guadalajara metropolitan area (officially, in Spanish: Zona Metropolitana de Guadalajara) is the most populous metropolitan area of the Mexican state of Jalisco and the third largest in the country after Greater Mexico City and Monterrey. It includes the core municipality of Guadalajara and the surrounding municipalities of Zapopan, Tlaquepaque, Tonalá, Tlajomulco de Zúñiga, El Salto, Ixtlahuacán de los Membrillos and Juanacatlán.

Chapultepec, more commonly called the "Bosque de Chapultepec" (Chapultepec Forest) in Mexico City, is one of the largest Nature Value Areas in Mexico, measuring in total just over 866 hectares (2,140 acres). Centered on a rock formation called Chapultepec Hill, one of the park's main functions is as an ecological space in Greater Mexico City. It is considered the first and most important of Mexico City's "lungs".

The area encompassing modern-day Chapultepec has been inhabited and considered a landmark since the pre-Columbian era, when it became a retreat for Aztec rulers. In the colonial period, Chapultepec Castle was built here, eventually becoming the official residence of Mexico's heads of state. It would remain so until 1934, when Los Pinos, in another area of the forest, became the presidential residence.

Ecatepec (Spanish: [ekateˈpek] ), officially Ecatepec de Morelos, is a municipality in the State of Mexico situated in the north of the Greater Mexico City urban area. The municipal seat is San Cristóbal Ecatepec.

The city of Ecatepec is co-extensive with the municipality, comprising 99% of the total population of 1,645,352. It is Mexico's third most-populous municipality after Tijuana and the 16 boroughs of Mexico City. It is also the most-populous suburb of Greater Mexico City.
