To the south, the ward of Barton is the third most densely populated in Salford with little population change between 1991 and 2001. It has proportionally more over-85-year-olds than the city as a whole, with low adult and primary school education standards, but significant improvements in GCSE results of late. Some parts of Barton are amongst the worst 20% of areas in the country for child poverty, with below-city-average childcare provision. Unemployment is higher than average for Salford. Almost half the homes in the ward are terraced housing, with an extra 300 properties built between 1994 and 2004. Economy To the east of the town centre, the West One retail park was opened in November 2001 at a cost of £53m. It is in competition with the nearby Trafford Centre and Lowry Outlet Mall, and as a result has suffered a loss of trade. Most of its units were abandoned but following the decision by Tesco to scrap plans for a £30m Tesco Extra store in 2013 a number of new openings have improved the retail offering; The Range, Home Bargains, Smyths Toys Superstores., PureGym and Jollyes Petfood Superstore. A Morrisons supermarket is near the town centre. One of the UK's largest online lighting retailers Value lights, is also located in an 80,000 square foot distribution centre in the centre of Eccles. Until shortly after its closure was announced on 9 May 2006, the Great Universal Stores group used the former Eccles Spinning and Manufacturing Company building in Winton. Operations have since been transferred to a site in Shaw and Crompton. The town still has a manufacturing industry. Valtris Speciality Chemicals (Ackros Chemicals prior to April 2016), a leading chemical additive supplier and its predecessors have occupied a site on Lankro Way since 1937, the site in Eccles employs more than 100 people working in manufacturing, research, administrative and business management roles. Americhem Europe manufactures colouring for plastics and nylon fibres, employing 75 staff with a turnover of £10m. The Eccles-based insurance broker and financial services specialist CBG Group, which worldwide employs 180 people, has its head office near the town centre.
