What this dot point is asking
SCSA wants you to know how the abstract idea of globalisation is turned into measurable data, how that data is mapped and ranked, and how to interpret such material in stimulus questions. This is a skills-focused dot point that appears constantly in the external paper.
Measuring globalisation with indices
Because globalisation is made of many flows, it is measured by combining indicators into an index.
Composite indices such as the KOF globalisation index score countries on economic, social and political connection. They reveal that small, open trading economies often rank highly, while large or isolated economies may rank lower despite their size. Such indices make comparison possible, but combining very different flows into one number hides detail and embeds value judgements about weighting.
Mapping flows and networks
Connectivity is most vividly shown through maps and diagrams.
- Flow-line maps use arrows whose width is proportional to the size of a flow, ideal for trade, migration or remittances.
- Network diagrams show nodes (places) and links (connections), capturing the structure of air routes, cables or trade.
- Choropleth maps shade areas by a connectivity value, such as internet penetration.
- Proportional symbol maps size symbols by a quantity, such as foreign investment received.
World cities and network rankings
Connectivity is also measured at the city scale. World-city or global-city rankings classify cities by their role in global finance, services and connectivity, identifying top-tier command centres such as New York, London, Tokyo and Singapore. These rankings show that globalisation concentrates control in a network of dominant cities rather than spreading evenly.
Spatial technologies and critical interpretation
GIS, satellite imagery and digital mapping let geographers layer and analyse connectivity data, for instance overlaying internet access on population. When interpreting any such representation, evaluate the source, the date, the units and what is left out. Informal flows, illegal trade and unrecorded migration are real but hard to measure, so the maps and indices always understate parts of reality.
A strong answer treats measurement as essential but imperfect, using indices, maps and rankings as evidence while acknowledging their limits.
A method for any stimulus
The examination almost always supplies stimulus material, so a reliable routine earns marks. First, orient yourself: read the title, key, units, scale and source date so you know exactly what is shown. Second, describe the spatial pattern using direction, named places and the data values, not vague words like "lots". Third, explain the pattern with geographical concepts such as time-space compression, core and periphery, or push and pull. Fourth, evaluate the representation by stating what it omits, how current it is, and how its design choices shape the impression it gives. Applying this same sequence to a flow-line map, a choropleth, a proportional-symbol map or a globalisation index turns description into the analysis and evaluation that top bands require.
Exam-style practice questions

WACE 202210 marksStudy the supplied flow-line map of international migration to Australia. Describe the patterns shown and explain how flow-line maps represent the size and direction of global flows. Identify two limitations of the data.Show worked answer →
A 10 mark stimulus response needs description, explanation of the technique, and limitations.
Describe the pattern. Read the map systematically: identify the widest arrows (the dominant source regions), describe the spatial pattern using compass and named regions, and quantify using the scale where one is provided. State the source and year.
How the technique works. Explain that flow-line maps use arrows whose width is proportional to the size of a flow and whose direction shows origin to destination, making them ideal for migration, trade or remittance data because they show magnitude and direction at once.
Limitations. Note any two: arrow overlap can obscure smaller flows; the data may be dated or omit informal and unrecorded movement; and combining many years or categories can hide change.
Markers reward systematic description, correct use of the scale, and specific limitations rather than vague comments.
WACE 20236 marksExplain why composite indices such as a globalisation index are useful for comparing places, and one limitation of using them.Show worked answer →
A 6 mark response needs the usefulness and a genuine limitation.
Usefulness. A composite index combines many indicators of economic, social and political connection into a single score, so countries can be ranked and compared on globalisation despite it being made of very different flows. This reveals patterns, such as small open economies ranking highly.
Limitation. Combining different flows into one number embeds weighting choices and hides detail, so two countries with the same score can be connected in completely different ways, and the index reflects the maker's judgements about what matters.
Conclude that indices enable comparison but must be read critically. Markers reward the comparison benefit and a specific limitation about weighting or lost detail.
