The city of Ciudad Juárez is in which Mexican state?

Ciudad Juárez is the most populous city in the Mexican state of Chihuahua. It is commonly referred to as Juárez and was known as El Paso del Norte (The Pass of the North) until 1888.

Juárez is the seat of the Juárez Municipality with an estimated population of 1.5 million people. It lies on the Rio Grande river, south of El Paso, Texas, United States. Together with the surrounding areas, the cities form El Paso–Juárez, the second largest binational metropolitan area on the Mexico–U.S. border (after San Diego–Tijuana), with a combined population of over 2.7 million people.

Juárez has grown substantially in recent decades due to a large influx of people moving into the city in search of jobs with the maquiladoras. A maquiladora, is a company that allows factories to be largely duty free and tariff-free. These factories take raw materials and assemble, manufacture, or process them and export the finished product. As of 2014 more technological firms have moved to the city, such as the Delphi Corporation Technical Center, the largest in the Western Hemisphere, which employs over 2,000 engineers. Large slum housing communities called colonias have become extensive.

Juárez has a long, notorious history of drug trafficking and the intense related violence. Mexico's first homegrown cartel, run by Ignacia Jasso, was seated in the city, and for a time controlled much of the border drug trade. Today the Juárez Cartel controls the routes in Juarez.
