Background
What is the population?
The official population count for Australia is the Estimated Resident Population (ERP), which is published quarterly in Australian Demographic Statistics (cat. no. 3101.0), Births, deaths and migration statistics are used to determine the Estimated Resident Population. The Census of Population and Housing is conducted every five years and provides a detailed snapshot of Australia’s population at that moment in time. It also serves as a benchmark for population estimates.
Changes to the Method of Collection
Census data may be returned in two ways, namely Place of Usual Residence and Place of Enumeration. Prior to 2006, a person was counted according to their location on Census night (Place of Enumeration). However, from 2006 onwards, data are primarily shown according to where they usually live (Place of Usual Residence).
Care should be exercised when making comparisons of Census data over time and the method of data collection should be clarified.
Geographic Units
In the Census, the smallest geographic area is a Collection District. It consists of approximately 225 households and generally represents the work of one Census collector. Collection Districts are aggregated to form larger geographic areas as part of the Australian Standard Geographic Classification (ASGC), (cat. no. 1216.0). A Statistical Local Area (SLA) is one of these larger geographic units and for this activity is the most appropriate way of representing the inner city area of Australia’s capital cities.
6.1 Where is the inner city?
Ask students to complete the following activities for a city of their choice.
1. Provide a map of the central area of the chosen city. Ask students to use the Australian Bureau of Statistics website for Census information www.abs.gov.au/census. Select ‘Census Data Online’ and the product 2006QuickStats. Use the ‘Search’ tab to locate the area of study. For all capital cities (except Brisbane, Canberra and Darwin) type in the name of the capital city and press ‘Search’. Select 'Statistical Local Areas' shown in Table 1. A new map is generated showing the boundaries of this area. To view statistics on the area click ‘View QuickStats’
To find the Statistical Local Area for inner Brisbane, Canberra and Darwin use the ‘Browse’ tab and search for the location ‘Statistical Local Area’. Brisbane is found within the Inner Brisbane Statistical Subdivision, Canberra within the North Canberra Statistical Subdivision and Darwin within the Darwin City Statistical Subdivision.
Ask students to shade their own map to show the boundaries of the Statistical Local Area covering the centre of the chosen capital city.
2. Identify the boundaries which form the northern, eastern, southern and western sides of the Statistical Local Area.
Does this area conform to your idea of the central part of the capital city? Discuss.
6.2 How many people live in the centre of our capital cities?
Activities in Section 6.2 should be completed in conjunction with the background information provided at the beginning of this section.
The Census of Population and Housing provides a snapshot of the population at a point in time. The Census is held in August during the school term.

Study Table 1 and for a chosen city answer the following questions:
1. Does the number of persons usually resident in the inner city outnumber the persons enumerated?
2. For the chosen city, calculate the difference between the two count methods. Account for the difference in populations recorded.
The Estimated Resident Population (ERP), which is based on the Census Place of Usual Residence count adjusted for births, deaths and migration is the official population count. Estimates are made annually for Statistical Local areas and they are published in Regional Population Growth (cat. no. 3218.0), see Table 2.
3. Using the official population count, the ERP (Table 2), rank Australia’s capital cities according to the population of the innermost Statistical Local Areas in 2007. Is the ranking one that was expected?

4. Are there persons in the inner city who may not have been counted on Census night?(answer provided)
6.3 Have the inner parts of our capital cities changed over time?
1. For a city of your choice and using Table 3, make a graph to show the growth in the number of people resident in the inner city between 1996 and 2006. (answer provided)
The average annual growth rate is calculated as a percentage using the formula below, where P0 is the population at the start of the period, Pn is the population at the end of the period and n is the length of the period between Pn and P0 in years.
2. Use the average annual growth rates provided in Table 3 to compare growth of your chosen city with that of other Australian cities in the period 1996- 2006.
3. In groups, ask students to discuss the changes taking place in the city to accommodate a growing population.

6.4 What is the population density of our inner cities?
1. Use Table 2, Estimated Resident Population at 30 June 2007, to identify the population density of your chosen city.
2. How is population density calculated?
3. How would population density change during a 24 hour period in the inner city areas?
4. Ask students to research how the population density of Australian inner city areas compares with the world’s major cities. Whilst completing this task ask the questions
(1) What is the source of the data?
(2) How was the data collected?
6.5 What are the characteristics of dwelling units in the inner city?
There has been a significant increase in apartment living in the inner cities due to population growth, changes in the composition of households, lifestyle choices and the high value of land. The Census of Population and Housing gathers data about dwelling types. A number of activities are provided below. Choose one or more activities to suit the student group.
1. For the city of your choice, use Table 4 and create a graph to show the change in the number of flats, units or apartments between 1996 – 2006.
2. Calculate the percentage increase in flats, units or apartments for the ten years from 1996 – 2006 for your chosen city.(answer provided)
3. For the city of your choice and with reference to the statistics calculated above and provided in Table 4, briefly describe the changes which have taken place in this type of private dwelling between 1996 and 2006 and provide reasons for the change identified.
4. Locate an image of a high rise apartment block (Google Maps satellite/Streetview may be helpful) and ask students to annotate it to show the advantages and disadvantages of living in this type of accommodation.

5. Debate the topic:
“Apartment living is the only sustainable way for Australians to live.”
6. Imagine that a two storey heritage precinct in the inner part of your chosen capital city is to be redeveloped into a 40 storey office and residential tower.
6.1 Create a role play to simulate the arguments which will be advanced by different members of the community to this proposal. Roles may include: A local council representative, a council officer responsible for granting the planning permission, a resident adjacent to the development who will be overlooked by the tower, a young person seeking accommodation in the city, an elderly citizen, a public transport activist, a local retailer, an environmentalist, an architect, a service provider (e.g. water, gas or electricity) and a historian.
6.2 The building is to be designed with ‘green’ credentials. Research methods of construction that are being implemented to make high rise city developments more environmentally sustainable.
7. Imagine the year is 2040 and there is a great deal of urban renewal taking place in the centre of your chosen city. The office and apartment blocks built at the end of the last century and the start of this century are being replaced by much higher towers. Following a visit (either real or virtual) to the inner city area to study the nature and distribution of the high rise towers, identify the towers that you would recommend for heritage status as classic examples of late twentieth century architecture. These towers will become heritage buildings and will therefore be protected against future urban renewal. With the aid of annotated photographs illustrate why the chosen high rise building should be preserved.
6.6 Who lives in the inner city?
1. The Estimated Resident Population (ERP) provides the most accurate count of the population. Use the statistics provided in Table 5a-c and the template or interactive age sex pyramid provided (see .xls file provided at the bottom of this page), to create an age sex pyramid for the capital city of choice. The age sex pyramids are also provided for comparison in the answer section of this activity.
2. Describe the pyramid by choosing the correct words in the spaces below.
The age sex pyramid presents males to the right/left and females to the left/right. The base of the pyramid is wider/narrower than the middle section and there were approximately …..………..children aged less than 15 years old. The top of the pyramid is wide/narrow, with approximately …………people over the age of 75 years. The sides of the pyramid representing the ages above 15 years are concave/ convex and the most prominent bulge occurs at ……………years. There are approximately ………….. people in this age category. The sides of the pyramid above 15 years of age slope evenly/unevenly. Males and females occur in similar/very different numbers throughout the age groups although there are more males than females in the following age groups ………… and more females than males in these age groups…………………………………..
3. Explain the shape of the pyramid by answering the following questions;
a) Why is the base narrow?
b) Why is the top narrow?
c) What reasons explain the large bulge in numbers?
d) What reasons explain variations between the sexes in the different age groups?
4. Ask students to brainstorm the advantages and the disadvantages of living in the inner city for people of different age groups e.g. very young children, young adults, working population and the elderly. In addition, discuss if they would like to live there?
