Urban Geography Glossary

Amenities: These may be within the home, in which case they refer to baths, toilets (w.c.'s), hot water etc., or outside people's homes in which case they would include parks, shops, public transport provision, etc..

Break of Bulk Point: the place where goods have to be unloaded e.g. a port.

Bridging Point: a settlement site where a river is narrow or shallow enough to be bridged. The bridge becomes a route centre and trading centre, the natural location for a market. It is also a good defensive site. The lowest bridging point on a river is the bridge nearest to the sea; this site is ideal for a river port settlement.

Brownfield land: urban land that has previously been developed, such as a the site of a demolished building or factory.

Burgess Model: an urban land use model showing five concentric zones, based upon age of houses and wealth of their inhabitants. (See concentric ring model).

By-pass: A road built around a busy urban area to avoid traffic jams.

CBD: Central Business District or city centre; the commercial and business centre ot a town or city where land values are at the highest. This is the most accessible part of the town or city. High land values lead to intensive use of the land and buildings are built as high as possible to maximise office space and therefore rental income.

Central Place: any settlement that provides goods and services for smaller neighbouring settlements.

City: cities are urban places. They are usually large (more than 20,000 people) and are economically self- sufficient (unlike a large dormitory or suburban town).

Clustered Settlement Pattern: a settlement where buildings are clustered around a particular point.

Commuting: the process by which people living in one place, travel to another place to work.

Comparison Goods/Services: these are high-order (usually expensive) goods such as antiques, jewellery, and some clothing and electrical equipment. They are called comparison goods because people like to compare prices, quality and other features before buying them. Comparison goods are usually sold in shops in city centres or large out-of-town shopping centres. People visit comparison shops only occasionally so they need a large market area.

Comprehensive Redevelopment: an area, usually in the inner city, where the whole urban landscape was demolished before being rebuilt on a planned basis by the council or city government.

Concentric Ring Model: see Burgess model.

Congestion: overcrowding on roads causing traffic jams.

Consumer: these are people. As trade in goods and services increases, the power of the consumer increases. Industries must create what people want (or think they need).

Conurbation: a large urban settlement which is the result of towns and cities spreading out and merging together.

Convenience Goods/Services: these are low/order goods - inexpensive things that vary little in price, quality or other features that we need to buy regularly e.g. newspapers, cigarettes and bread. Convenience shops are found on most street corners where they have a small market area of people who visit the shop on most days.

Corner Shop a shop typical of the inner city zone (but also common in all zones except the CBD) found on every street corner, selling a range of every-day needs. (See convenience goods and low-order goods/services).

Counterurbanisation: The movement of people from the MEDC cities to the countryside seeking a better quality of life. Many still commute into the city to work, but increasing numbers are moving to completely change their lifestyle and work in the rural area, often by teleworking.

Cycle of Deprivation: a sequence of events experienced by disadvantaged people in which one problem e.g. lack of work, leads to other problems and so makes things worse.

Defensive Site: a settlement which usually grew at or around a fort or castle on top of a hill, although river meander bends, bridges, dry-point sites and coastal sites with cliffs were also good for defence.

Demand: the willingness and ability of consumers to pay for a particular good or service; As long as the supply of goods and services meets the demand, prices remain the same (stable). High demand for land in the CBD from businesses wishing to locate there results in very high land values because supply cannot be increased to meet the demand.

Dependant person: This is either a dependant child, or a person with long-term sickness preventing him/her from working.

Deprivation: The degree to which an individual or an area is deprived of services and amenities. There are many different types and levels of deprivation included poor and overcrowded housing, inadequate diet, inadequate income and lack of opportunity for employment.

Formal Sector: the employment sector comprising 'proper' jobs that are usually permanent, with set hours of work, agreed levels of pay, and sometimes pensions and social security rights.

Function of a Settlement: what the settlement does to 'earn its living' e.g. market town, mining town, administrative centre, tourist resort etc..

Gap Town: a town located at a gap between hills, providing a good defensive site and route centre that led to a trade and market function.

Gentrification: a process by which run-down houses in an inner city or other neglected area are improved by better off (affluent) people who move there in order to have easier access to the jobs and services of the city centre. The 'improving' social group changes attract more people of the similar wealthier social group.

Green Belt: An area around a city, composed mostly of parkland and farmland, in which development is strictly controlled. Its purpose is to prevent the outward growth of the city, preserve countryside for farming, wildlife and recreation, and, often to prevent two or more cities from merging to form one huge urban area.

Hypermarket: a giant shopping centre containing a very large supermarkets and other smaller shops found in an out-of-city location, close to a motorway junction. It benefits from cheap land and the new trend to shopping by car, with large carparks to cater for this. Prices are kept low by the supermarket buying in bulk which enables it to negotiate the lowest possible prices from its suppliers.

Primate City: some countries have one city - the primate city - which, in terms of its population size and functions, dominates all other urban places.

Professional Occupations: these comprise employers, managers and professional workers whose occupations normally require a university degree or other highly selective qualification such as doctors, civil engineers, etc..

Quality of Life: an idea which is difficult to define because it means different things to different people. Things which make for a good quality of life might include high income, good health, good housing, basic home amenities, pleasant surroundings, recreational open space, good local shops, a secure job, etc..

Range of a Good: the maximum distance that people are prepared to travel for a specific service.

Ribbon development: when housing grows out from a town along a main road.

Ring-road: a by-pass that provides a route around the CBD.

Route Centre: a settlement located at the meeting point of several roads/railways; the meeting point of two or more river valleys (which provide good road and rail routes through high land), is often the location of a route-centre settlement. Bridging points, ports and gap towns are also natural route centres.

Rural-Urban Fringe: a zone of transition between the built-up area and the countryside, where there is often competition for land use. It is a zone of mixed land uses, from shopping malls and golf courses to farmland and motorways.

Second Homes: homes purchased by city dwellers in country villages or areas of usually great natural beauty for holiday or weekend use only. These create problems for local communities since house prices in the area of second homes rise out of the reach of young people, and shops, schools and bus services are forced to close due to lack of customers. The newcomers also bring unwanted social changes to the villages.

Sector Model: see Hoyt model.

Local people can then obtain a plot in the scheme for a low rent and build their own houses.

Situation: the location of a settlement in relation to places (physical and human) surrounding it e.g. roads, rivers, land use etc. A settlement with a good situation is likely to grow to become a market town for the surrounding region.
