MEXICO CITY AND THE ZMVM The Zona Metropolitana Del Valle de Mexico (ZMVM) includes 16 delegations of the Federal District (D.F.) and 59 surrounding municipalities belonging to the State of Mexico. Because the Urban settlement area has spread over the boundaries of the D.F., a further boundary that encompases the entire urban population of Mexico City is a helpful tool in understanding the extents of this city, the second largest Urban Agglomeration in the world.

METROPOLITAN AREAS SURROUNDING THE ZMVM Housing almost 20% of Mexico s population, Mexico City is the political, economical and cultural heart of the Country. The Zocalo, the historic center of the city is bordered by the Metropolitan Cathedral and the Palacio National, the seat of Mexico s federal government.
TOPOGRAPHY ZMVM The city is located in a Volcanic Upland Basin, 2,240m above sea level. The valley it occupies is surrounded on all sides by mountains and volcanoes rising in places to almost 4000m above sea level. This geographical barrier limits further expansion of the city and traps city smog and pollution within the valley, exacerbating the air-quality problem.

SHRINKAGE OF THE LAKE SYSTEM IN THE VALLEY OF MEXICO The Valley of Mexico is a closed hydrological system. Human intervention taking place throughout the last 500 plus years has artificially drained the lake system. Originally, before the founding of the Aztec city of Tenochtitlan, the lake system covered an area of 1,500 km2. The original Aztec city was built on a marshy island which was enlarged by infilling adjacent land and planting trees to stabilize the edges. Site of Tenochtitlan 1500 1600 Because of its location on an old lake-bed, Mexico City has settlement issues affecting many of its older buildings (image right) and making the construction of larger buildings challenging in many areas of the city. Certain areas of the city are sinking at an alarming rate, due to the continuous extraction of water for drinking purposes from the subterrenean aquifer. 1700 2000 ZMVM 1er edicion, 2000.

URBAN GROWTH Population migration from Mexico s rural areas to Mexico City and a steep increase in the birth-rate have pushed Mexico City from a city of 560,000 in 1910 to the second biggest city in the world, after Tokyo, with a population of 18 million. 1900 1940 1950 Beginning in the 30s, Mexico City saw a surge in population growth. Fuelling this growth was a government push towards import substitution, a strategy aimed at economic growth by encouraging increased national industrial production of items traditionally imported. The resulting industrial growth, especially in larger cities and predominantly in Mexico City, spurred a migration trend from rural areas to the cities. pop. 344,721 27 km² pop. 3,100,000 229 km² pop. 5,400,000 470km² This surge in population that saw Mexico City s population double every 15 years through much of the 20th century was translated into an urban housing problem that persists today. 1970 1980 2000 pop. 9,200,000 682 km² pop. 12,900,000 1056 km² pop. 18,100,000 1,325 km² ZMVM 1er edicion, 2000.
