Single farmsteads, the many surviving old clachans (clusters or hamlets), and occasional villages and small towns still characterize much of the highland zone. Some nucleated settlement patterns, however, have undergone radical change. In Wales hamlets began to disappear in the late Middle Ages through the related processes of consolidation and enclosure that accompanied the decline in the size of the bond (feudally tied) population. The Black Death of 1349, which spread quickly among poorer inhabitants, reinforced this trend. Many surviving bondsmen fled their servile obligations amid the turmoil of the nationalistic uprising led by Owain Glyn Dŵr. Thus, many Welsh hamlets had fallen into decay by 1410, when the rebellion was crushed. In Scotland great changes accompanied the late 18th-century Highland clearances, in which landlords forcibly evicted tenants and converted their holdings to sheep pastures. As late as the 1880s many clachans disappeared in Northern Ireland as part of a deliberate policy of reallocating land to new dispersed farmsteads. Great changes have also occurred in the lowland zone, where the swing to individual ownership or tenancy from the medieval custom of landholding in common brought about not only dispersion and deserted villages but the enclosure of fields by hedges and walls. Villages remain remarkably stable features of the rural landscape of Britain, however, and linear, round, oval, and ring-shaped villages survive, many with their ancient greens still held in common by the community.
Urban settlement
By any standard the United Kingdom is among the most urbanized of countries, for towns not only typify the national way of life but are unusually significant elements in the geography of the country. The greatest overall change in settlement was, in fact, the massive urbanization that accompanied Britain’s early industrial development. The increasing percentage of employees in offices and service industries ensures continued urban growth. Of every 10 people in the United Kingdom, about eight live in towns—more than three of them in one of the country’s 10 largest metropolitan areas. The Greater London metropolitan area—the greatest port, the largest centre of industry, the most important centre of office employment, and the capital city—is by far the largest of these. The need for accommodating business premises has displaced population from Inner London, and this outward movement, in part, has led to the development of new towns outside the 10-mile- (16-km-) wide Green Belt that surrounds London’s built-up area.
Large metropolitan areas also formed in industrial areas during the 19th and early 20th centuries. Although coalfields or textile manufacture underpinned the initial growth of many of these urban areas, coal mining had virtually ceased in all of them by the end of the 20th century, and the economic predominance of heavy industry and textile production had given way to a more diverse blend of manufacturing and service activities. Birmingham dominates the extensive built-up area of the West Midlands metropolitan area, but the industrial Black Country—named for its formerly polluted skies and grimy buildings—also has several large and flourishing towns. In Greater Manchester, with a similar number of inhabitants, urbanization accompanied the mechanization of the cotton textile industry. Across the Pennines similar mechanization of wool textiles created the West Yorkshire metropolitan area, with Leeds and Bradford as its twin centres. The metropolitan area of Tyne and Wear (centred on Newcastle upon Tyne) and the Greater Glasgow metropolitan area are also located on coalfields. Greater Glasgow houses about one-third of Scotland’s people. Merseyside (centred on Liverpool) has traditionally served as a seaport and distribution centre for Greater Manchester and the rest of Lancashire. Other large metropolitan areas in Great Britain include South Yorkshire (centred on Sheffield), Nottingham, and Bristol. About one-fifth of Northern Ireland’s population live in Belfast. In addition to these large metropolitan areas, there are many other minor urban agglomerations and large towns, several of which line the coast.
