Population change Until the late 18th century, Horwich was a small rural community. In 1774, it had a population of 305, comprising 156 females and 149 males. After 1780 the population increased as the Industrial Revolution brought changes to the town but remained constant until 1885 when the locomotive works were built more than trebling the population in ten years. Economy Many of Horwich's traditional industries, Horwich Works and W.T. Taylor's cotton mill closed in the late 20th century. Regeneration was led by the construction of the University of Bolton Stadium for Bolton Wanderers at Middebrook in 1995. The development which stretches into neighbouring Lostock, attracted industrial and commercial users including Hitachi, generating jobs to replace those lost in the old industries and the area is now dominated by small and medium enterprises. E.ON and RBS have set up offices close the University of Bolton stadium. Watson Steel Structures founded in 1933 and BAe's successor company, Matra BAe Dynamics operates from the Middlebrook area. Georgia Pacific has a paper manufacturing plant close to the University of Bolton Stadium. Halbro, manufacturers of sportswear and equipment for both codes of rugby, is based on Chorley New Road. There are Tesco and Asda stores on the outskirts of town and Aldi and Iceland stores closer to the town centre. EU grants have contributed to new "traditional style" shop fronts in the town centre, which has many small specialist shops. The Horwich indoor market
