The northern section of the state, containing most of the Valley of Mexico (part of the Anáhuac plateau), has broad, shallow lakes and is broken by low mountains. There are steeper mountains and valleys in the east, and the southern and western areas are dominated by the rugged volcanic belt extending across the center of the country. On the state's southeastern border are the Popocatépetl and Iztaccíhuatl volcanoes. The principal river is the Lerma. Except on the south, the state encircles the Federal District, and most of the eastern part lies within the Mexico City metropolitan zone. Suburbs of Mexico City that lie within Mexico state include Ciudad Nezahualcóyotl, a huge (more than 2 million) working-class city, and the major industrial centers of Naucalpan, Tlalnepantla, Ecatepec, Tultitlán, and Cuautitlán. The state is highly industrialized and is a leading producer of automobiles, paper, chemicals, textiles and clothing, other light manufactures, iron, and steel.
