This mixed-use district also contains large blocks of residential complexes, so as well as strips of small to medium-sized shopping districts. It previously had only an area of 39 km2 (15 sq mi)[69] and a population of 764,419.[70] In May 2002, the Shenyang city government annexed a large area of suburban land from the neighbouring Yuhong District to establish a new state-level development zone—the Shenyang Economic and Technological Development Zone (沈阳经济技术开发区), and transferred its administration to Tiexi District to form the Tiexi New District (铁西新区), thus giving Tiexi District the current "necked" shape on the map. The new Tiexi District now has a population of 907,091 (2014),[3] a total area of 286 km2 (110 sq mi),[4] and enjoys the same administrative rank as a municipality (Administrative Committee of Shenyang).
