full_context: Document 1: Southampton: Between 1996 and 2004, the population of the city increased by 4.9 per cent—the tenth biggest increase in England. In 2005 the Government Statistics stated that Southampton was the third most densely populated city in the country after London and Portsmouth respectively. Hampshire County Council expects the city's population to grow by around a further two per cent between 2006 and 2013, adding around another 4,200 to the total number of residents. The highest increases are expected among the elderly.
Document 2: Southampton: Southampton is divided into council wards, suburbs, constituencies, ecclesiastical parishes, and other less formal areas. It has a number of parks and green spaces, the largest being the 148 hectare Southampton Common, parts of which are used to host the annual summer festivals, circuses and fun fairs. The Common includes Hawthorns Urban Wildlife Centre on the former site of Southampton Zoo, a paddling pool and several lakes and ponds.
Document 3: Southampton: There are 119,500 males within the city and 117,400 females. The 20–24 age range is the most populous, with an estimated 32,300 people falling in this age range. Next largest is the 25–29 range with 24,700 people and then 30–34 years with 17,800. By population, Southampton is the largest monocentric city in the South East England region and the second largest on the South Coast after Plymouth.
Document 4: Winchester: Winchester is a city and the county town of Hampshire, England. The city lies at the heart of the wider City of Winchester, a local government district, and is located at the western end of the South Downs National Park, along the course of the River Itchen. It is situated 60 miles (97 km) south-west of London and 13.6 miles (21.9 km) from Southampton, its closest city. At the time of the 2011 Census, Winchester had a population of 45,184. The wider City of Winchester district which includes towns such as Alresford and Bishop's Waltham has a population of 116,800.Winchester developed from the Roman town of Venta Belgarum, which in turn developed from an Iron Age oppidum. Winchester's major landmark is Winchester Cathedral, one of the largest cathedrals in Europe, with the distinction of having the longest nave and overall length of all Gothic cathedrals in Europe. The city is home to the University of Winchester and Winchester College, the oldest public school in the United Kingdom still using its original buildings.
Document 5: Southampton: The town experienced major expansion during the Victorian era. The Southampton Docks company had been formed in 1835. In October 1838 the foundation stone of the docks was laid and the first dock opened in 1842. The structural and economic development of docks continued for the next few decades. The railway link to London was fully opened in May 1840. Southampton subsequently became known as The Gateway to the Empire.
Document 6: Southampton Common: Southampton Common is a large open space to the north of the city centre of Southampton, England. It is bounded by the districts of Shirley, Bassett, Highfield and Portswood. The area supports a large variety of wildlife, including the largest recorded population of the internationally rare great crested newt. It is designated a Site of Special Scientific Interest. The Common is used for a wide variety of community events, Flower Festival, Race for life Cancer Research UK and formerly 'Power in the Park' hosted by Power FM.
Document 7: Southampton: Southampton's police service is provided by Hampshire Constabulary. The main base of the Southampton operation is a new, eight storey purpose-built building which cost £30 million to construct. The building, located on Southern Road, opened in 2011 and is near to Southampton Central railway station. Previously, the central Southampton operation was located within the west wing of the Civic Centre, however the ageing facilities and the plans of constructing a new museum in the old police station and magistrates court necessitated the move. There are additional police stations at Portswood, Banister Park, Bitterne, and Shirley as well as a British Transport Police station at Southampton Central railway station.
Document 8: Southampton Terminus railway station: Southampton Terminus railway station served the Port of Southampton and Southampton City Centre, England from 1839 until 1966. The station was authorised on 25 July 1834 and built as the terminus of the London and Southampton Railway, which later changed its name to the London and South Western Railway (LSWR). The station opened as "Southampton" on 10 June 1839, although it was not officially operational until 11 May 1840, due to the track not being fully linked between Winchester and Basingstoke.
Document 9: Southampton: Town Quay is the original public quay, and dates from the 13th century. Today's Eastern Docks were created in the 1830s by land reclamation of the mud flats between the Itchen & Test estuaries. The Western Docks date from the 1930s when the Southern Railway Company commissioned a major land reclamation and dredging programme. Most of the material used for reclamation came from dredging of Southampton Water, to ensure that the port can continue to handle large ships.
Document 10: Somerset: The usefulness of the canals was short-lived, though some have now been restored for recreation. The 19th century also saw the construction of railways to and through Somerset. The county was served by five pre-1923 Grouping railway companies: the Great Western Railway (GWR); a branch of the Midland Railway (MR) to Bath Green Park (and another one to Bristol); the Somerset and Dorset Joint Railway, and the London and South Western Railway (L&SWR). The former main lines of the GWR are still in use today, although many of its branch lines were scrapped under the notorious Beeching Axe. The former lines of the Somerset and Dorset Joint Railway closed completely, as has the branch of the Midland Railway to Bath Green Park (and to Bristol St Philips); however, the L&SWR survived as a part of the present West of England Main Line. None of these lines, in Somerset, are electrified. Two branch lines, the West and East Somerset Railways, were rescued and transferred back to private ownership as "heritage" lines. The fifth railway was a short-lived light railway, the Weston, Clevedon and Portishead Light Railway. The West Somerset Mineral Railway carried the iron ore from the Brendon Hills to Watchet.
Document 11: Southampton: Southampton is also served by the rail network, which is used both by freight services to and from the docks and passenger services as part of the national rail system. The main station in the city is Southampton Central. Rail routes run east towards Portsmouth, north to Winchester, the Midlands and London, and westwards to Bournemouth, Poole, Dorchester, Weymouth, Salisbury, Bristol and Cardiff. The route to London was opened in 1840 by what was to become the London and South Western Railway Company. Both this and its successor the Southern Railway (UK) played a significant role in the creation of the modern port following their purchase and development of the town's docks.
Document 12: Southampton: Local train services operate in the central, southern and eastern sections of the city and are operated by South West Trains, with stations at Swaythling, St Denys, Millbrook, Redbridge, Bitterne, Sholing and Woolston. Plans were announced by Hampshire County Council in July 2009 for the introduction of tram-train running from Hythe (on what is now a freight-only line to Fawley) via Totton to Southampton Central Station and on to Fareham via St. Denys, and Swanwick. The proposal follows a failed plan to bring light rail to the Portsmouth and Gosport areas in 2005.
Document 13: Southampton: Southampton (i/saʊθˈæmptən, -hæmptən/) is the largest city in the ceremonial county of Hampshire on the south coast of England, and is situated 75 miles (121 km) south-west of London and 19 miles (31 km) north-west of Portsmouth. Southampton is a major port and the closest city to the New Forest. It lies at the northernmost point of Southampton Water at the confluence of the River Test and River Itchen, with the River Hamble joining to the south of the urban area. The city, which is a unitary authority, has an estimated population of 253,651. The city's name is sometimes abbreviated in writing to "So'ton" or "Soton", and a resident of Southampton is called a Sotonian.
Document 14: Southampton: In the 2001 census Southampton and Portsmouth were recorded as being parts of separate urban areas, however by the time of the 2011 census they had merged to become the sixth largest built-up area in England with a population of 855,569. This built-up area is part of the metropolitan area known as South Hampshire, which is also known as Solent City, particularly in the media when discussing local governance organisational changes. With a population of over 1.5 million this makes the region one of the United Kingdom's most populous metropolitan areas.
Document 15: Southampton: There are two main termini for bus services. As the biggest operator, First uses stops around Pound Tree Road. This leaves the other terminal of West Quay available for other operators. Uni-link passes West Quay in both directions, and Wilts & Dorset drop passengers off and pick them up there, terminating at a series of bus stands along the road. Certain Bluestar services also do this, while others stop at Bargate and some loop round West Quay, stopping at Hanover Buildings. There was a tram system from 1879 to 1949.
