Faisalabad is the third largest city of Pakistan.
Faisalabad was restructured into city district status; a devolution promulgated by the 2001 local government ordinance (LGO). The total area of Faisalabad District is 5,856 km2 (2,261 sq mi) while the area controlled by the Faisalabad Development Authority (FDA) is 1,280 km2 (490 sq mi). Faisalabad has grown to become a major industrial and distribution centre because of its central location in the region and connecting roads, rails, and air transportation. It has been referred to as the "Manchester of Pakistan". Faisalabad contributes over 20 percent of Punjab's GDP, and has an average annual GDP of $20. 5 billion. Agriculture and industry remain its hallmark. The surrounding countryside, irrigated by the lower Chenab River, produces cotton, wheat, sugarcane, maize, vegetables and fruits. The city is an industrial centre with major railway repair yards, engineering works, and mills that process sugar, flour, and oil seed. Faisalabad is a major producer of superphosphates, cotton and silk textiles, hosiery, dyes, industrial chemicals, beverages, clothing, pulp and paper, printing, agricultural equipment, and ghee (clarified butter).
