Census data are being delivered in a number of new formats which are free online. Articles in Education News (cat.no 1330.0) for 2007 illustrate how to search for Census data.
The activity uses three of the Census products, namely QuickStats, Census Tables and MapStats. QuickStats provides summary data in tabular form, MapStats creates thematic maps from census data, and Census Tables provide detailed data as an Excel spreadsheet on a particular Census topic. For a very detailed investigation of an area a Community Profile may be of more use. All of these products are available for areas as large as Australia or as small as a Collection District (about 230 households) and a range of geographic units in between. All are free on the web.
The activity could be completed in small groups or individually. The activity develops a range of graphing styles, such as column, pie, compound column or bar graphs and population pyramids.
6.1 Create a Community Profile: What Does the Area Look Like?
Create a profile of a chosen suburb or locality. The profile should include the location and physical characteristics of the area in addition to its demographic and socio-economic characteristics.
1. Select a suitable area. Use a street directory, a topographic map, or the maps created from Census data to describe the location of the area, using appropriate geographic language and conventions.
2. Use a topographic map, or images from Google Earth to describe the natural or physical characteristics of the chosen area.
6.2 Using 2006 Census QuickStats: How Does the Area Compare with Benchmark Australian Values?
Go to www.abs.gov.au\census to access QuickStats for the chosen area. From the QuickStats table choose statistics about persons, families and dwellings to provide a picture of the area. Note the benchmark Australian values for comparison. Some statistics are provided in Table 1 as an example.
1. A map of the chosen district is generated when accessing Census data. Use the line scale on this map to estimate the area of the district being studied.
2. Obtain the population of the chosen area from the QuickStats table. Use the population and the area in km2 to calculate the approximate population density of the locality in persons per square kilometre. The following formula will be useful:
Population density = Number of People / Area of land (square kilometres)
3. Australia’s population density at 30 June 2006 was 2.7 people per square kilometre (Yearbook Australia, 2008, cat. no. 1301.0). How does the population density of the chosen area compare with that of Australia?
4. Use the summary data provided in QuickStats (see example in Table 1) to create graphs to represent the selected statistics about persons, families and dwellings. Make comparisons with Australian statistics by creating similar graphs for the benchmark Australian values provided. Explore a range of presentation options such as tables, column graphs or bar charts.

5. Explore the concept of median income by asking students to define the term median and explain why median income is used in preference to mean income in the QuickStats tables.
6. Develop the range of graphing types by asking students to present the labour force statistics for the chosen area as either a pie graph or as a compound column graph as shown in Figure 1.

6.3 Using 2006 Census Tables: What does a Population Profile of the Area Look Like?
Census Tables provide detailed statistics for a location which may be downloaded as an Excel spreadsheet. Download the Census Table showing the age and sex of the population in the chosen local area.
1. Simplify the table to present the age and sex of the population in 5 year intervals, as shown in Table 2. Represent these statistics as a percentage of the total population of the area as shown in Table 2, (not required if completing an interactive population pyramid).
2. Construct a population pyramid for the locality. This may be done using the interactive population pyramid provided with this activity or the paper version (See Geo_10 attachment) The vertical axis represents the percentage of the population in each 5 year age group and on the horizontal axis males are represented to the left and females to the right
3. Describe the shape of the population pyramid for the chosen location. Use the following guidelines to structure the description: width of base, width of top, shape of the sides, height of the graph, proportion of males and females. Accompany the description with statistics taken from the population pyramid.
4. What explanations may be given for the shape of the population pyramid in Peppermint Grove?

6.4 Using 2006 Census MapStats: What Spatial Patterns Exist within the Area?
The Census product MapStats provides thematic maps of a district. Topics include age and population distribution, ancestry, birthplace, childcare, children, cultural and language diversity, educational attainment, employment, family formation and dissolution, hours worked, household characteristics, housing costs, income, indigenous population size and distribution, labour force participation, language, living arrangements, migrants, migration, occupation, people with a disability, school education, transport access and use, unpaid household work and voluntary work.
Go to <www.abs.gov.au\census> and select the MapStats product for Census 2006.
1. Select two MapStats topics which enhance the information about the demographic and socio-economic characteristics of the locality and create maps using MapStats.
2. Create two maps of the community using MapStats. Obtain as much detail by downloading a map showing the smallest geographic area e.g. Collection District.
3. For each map describe the distribution of the characteristics chosen. This should be done by using the following guidelines and supporting the description with statistics extracted from the map.
· Is the pattern even or uneven?
· Where are most?
· Where are least?
· Are there exceptions?
4. Compare the distributions shown by the two maps generated above.
6.5 Putting the Profile Together
Use the Quickstats, Census Tables and MapStats to describe the characteristics of the area.
1. Describe the demographic and socio-economic characteristics of the area to develop a profile of the community.
2. This activity could be extended so that students share their written descriptions with another student. Ask students to review their peer’s work and ask them to answer these questions: Is the account well organised? How well does it create a picture of the locality? Does the account include sufficient statistics? How would you improve this piece of writing?
3. Working in groups, create a digital video to represent the local area and community. Integrate visual images of the district with graphic material to provide a picture of the local area.
