Londonās complicated topography can be made simple by means of three basic patterns. First, there is the undulating line of the Thames separating northern from southern London. For historical reasons, most important destinations lie north of the river. The south is essentially an intricate patchwork of residential districts joined by miles of conventional through streets. It has no fast through roads.

In addition, London differs from east to west. The waters of the Thames and the prevailing winds flow eastward. Therefore, shipping, heavy haulage, manufacturing, and laboring districts developed downstream in the East End, while the affluent and leisured classes built their homes and pursued their pleasures in the West End. This social gradient was reinforced by the location of the royal palaces at Westminster, Kensington, Richmond, and (beyond Londonās boundary) Windsor. Partly in consequence, the western sector has a series of tranquil and elegant open spaces on either side of the river, from St. Jamesās Park, by the prime ministerās house at No. 10 Downing Street, through Hyde Park, Kensington Gardens, Battersea Park, Wimbledon Common, Richmond Park, the Royal Botanic Gardens at Kew, the Richmond riverbank, Hampton Court Park, and Bushey Park. Their landscapes soften the effect of noise pollution under the flight path of Heathrow Airport, on the western border. Proximity to one of the worldās busiest international airports has itself reinforced the favored position of western London.
The east-west divide is entrenched equally in the physical fabric of London and in the psychology of Londoners. Its significance, however, began to diminish in the later years of the 20th century as port and manufacturing activity declined and was replaced by white-collar work and residents. This process was accelerated in 1981ā98 when the London Docklands Development Corporation undertook the regeneration of a vast tract of derelict docklands at the eastern end of the cityāan area that included Wapping, Limehouse, the Isle of Dogs, the Royal Docks, Beckton, Surrey Docks, and Bermondsey Riverside. (See also London Docklands.)
Finally, overlying the north-south and east-west distinctions is a simple concentric ring pattern that reflects the historical phases of Londonās growth. At the center is the area familiar to visitorsāthe City of London, a 1.1-square-mile (2.8-square-km) municipal corporation and borough of London, with its offices, shops, and public buildings. The first ring surrounding that area, the suburban beltāknown for statistical purposes as Inner Londonādeveloped from the late 18th century until the beginning of World War I. There terraced houses predominate, and the building scale is domestic and intimate, except where the original units were replaced by higher-density rental housing built by local councils in areas of World War II bomb damage or postwar clearance. The third zoneāOuter Londonāconsists of 20th-century suburban housing, chiefly created in a short, intensive building boom in 1925ā39. The most common building type is the semidetached unit, a distinctively British compromise between row housing and the freestanding homestead. The Metropolitan Green Belt forms a final concentric ring, defining the shape of the whole capital.

Demographic trends
From a total population of 5.6 million in 1891, London grew by 3 million to its peak magnitude at the outbreak of World War II. For several decades after the war, its population shrank by approximately 2 million, to some 6.6 million in the mid-1980s. The decline occurred for reasons common to all large cities of its type. Increasing leisure and holiday time, shorter working hours, and access to the automobile freed people from the ties of proximity to their place of work. Families moved out of town in search of a better quality of life. Firms moved for similar reasons, seeking more spacious and accessible sites. As the remaining population spread itself more comfortably in the dwelling stock, the three-generation household became a rarity except among ethnic minorities. Mass housing initiatives and individual āgentrificationā of terraced houses tended equally to reduce population density.
The steepest fall occurred in the densest areas. Inner London boroughs lost more than one-third of their population in the postwar decades. In the 1980s the slump was eased by a fall in the rate of out-migration and a rise in the birth rates of new immigrant families. Londonās population began slowly growing again in the 1990s, and by 2000 it had surpassed seven million; it is thus comparable in size to New York City, though the latter metropolis sits in a wider urban region with approximately three times the population of Greater London.
