  2. Cities have been ‘invented’ several times In the ‘Fertile Crescent’, the Valley of the Tigris and Euphrates in what is now Iraq during the 4th millennium BC

  3. In the Nile Valley ca. 3000 BC

  4. In the Indus Valley of Pakistan ca 2500 BC

  5. Other Places of Urban ‘Invention’ • The Yangtze Valley, ca 2000 BC • The Americas: Inca ca 800 AD Aztec ca 600 AD

  16. Cities have always served more of less the same functions, providing sites of Defense Places of worship Education Fostering of culture Administration Shelter Production and Consumption Processes/Properties of the City (manual, p. 89) Production Reproduction Proximity Capitalization Sense of Place Governance Multiple urban origins, similar functions

  17. Four Ways of DefiningThe City • Social - Demographic • Functional or Economic • Legal or Administrative • Statistical

  18. Definition 1: Social - Demographic • A city can is a human settlement that is: • Large • Densely populated • Permanent • Socially heterogeneous, housing non agricultural specialists and a literate elite (Louis Wirth, 1938)

  19. The Importance of Density(Manual, p. 94)How dense is dense?(persons/km2)

  20. Downtown St. John’s 4,000

  21. Chinatown, Toronto9,000

  22. St. Jamestown, Toronto80,000

  23. Mumbai43,000

  24. Definition 2:Functional or Economic The function of a city is to provide goods and services to its own people and (usually) to a surrounding population (local, regional, national or global) as well

  25. Defining a city • Functional or Economic • Only a small proportion of the population is engaged in primary activities such as fishing, farming or forestry • Most of the population is engaged in ‘secondary’, ‘tertiary’ or ‘quaternary’ activities • Manufacturing • Trade (wholesale, retail) • Finance • Administration • Education • Religion

  26. Definition 3:Legal or Administrative A city usually has a legal existence, incorporated as a city or town under some appropriate legislation, and with a defined territory.

  27. St. John’s was incorporated in 1888 St. John’s, 1859

  28. Prior to that it did not exist legally. • But it did exist as a large, densely populated, permanent, socially heterogeneous settlement (Definition 1), and it performed urban economic functions (Definition 2) for the country. St. John’s, 1859

  29. Definition 4:Statistical Statistical agencies like Statistics Canada make their own definitions of cities. Usually the purpose is to define a metropolitan area that approximates the area thatfunctions as a single urban settlement. The Census Metropolitan Area (CMA) is the most common of these statistical areas.

  30. This map shows the two cities of St. John’s and Mount Pearl, and ten of the towns on the Avalon Peninsula.

  31. The goal is to define a metropolitan area that approximates the area that functions as a single urban settlement – in Canada we attempt to delineate the area defined by the daily labourshed. • The Census Metropolitan Area (CMA) is the most common of these statistical areas.

  32. Diagram of CMA

  33. The Census Metropolitan Area (CMA) according to StatsCan • The CMA is an area consisting of an urban core plus one or more adjacent municipalities situated around the core. To form a census metropolitan area, the urban core must have a population of at least 100,000. To be included in the CMA, other adjacent municipalities must have a high degree of integration with the central urban area, as measured by commuting flows.
