Greater London.

Greater London, composed of 14 inner boroughs and 19 outer ones, covers 1,579 square kilometers and has a population density of 77.9 persons per hectare. From 1971-1981, Greater London decreased in population by 10%, declining from 7.45 million to 6.71 million. All outer boroughs and 13 inner boroughs lost population in the 1970s; only the historic financial and business center--the City of London--showed a population increase. 48% of the population is male and somewhat over 60% of the total population is between 16 and pensionable age. Inner London includes more 25-44 year olds than Outer London. In Greater London 18% of the population was born in foreign countries, with almost a quarter of Inner London's residents being foreign born. Men (15%) and women (16%) in Inner London and men (16%) and women (13%) in Outer London are likely to have more education than other Britons. Somewhat more working women are found in Greater London than in the rest of Great Britain, with the highest percentage in the City of London. 34% of British households include children under age 16, but only 29% of Greater London's households include children. Only 10% of the City of London's households have children, and 1/4 of mothers work, as compared to 13% for all of Britain. A majority of Greater London households have either no car or only 1 car since public transportation and walking to work are convenient. Greater London households declined by 5% to 2.5 million in 1981, with average household size declining from 2.8 to 2.6 persons; 26% are single-person households (55% of these are pensioners). As in the rest of Britain, more people are buying homes and renting them from local authorities. 1/3 of Greater London residents live in publicly owned housing. Some lifestyle variations exist between Greater London residents and other Britons in terms of household consumption, but these differences are not as great as geographic differences in the US, and Greater London demographic data may be used to determine potential markets for each of its boroughs.
