Flows of people and migration: WACE Year 12 Geography
“Analyse the causes, patterns and consequences of international flows of people”
International migration is the movement of people across national borders, driven by push factors in source places and pull factors in destination places; it reshapes both ends of the flow demographically, economically, socially and politically, producing benefits such as remittances and labour, alongside costs such as brain drain and social tension.
What this dot point is asking
SCSA wants you to classify the different types of human movement, explain why people move using push and pull factors, describe the global patterns these movements form, and evaluate the consequences for both source (origin) and destination places. A strong answer separates voluntary from forced migration and supports every point with current, named examples.
Types of international movement
Not all flows of people are the same, and the distinctions matter for marks.
- Permanent migration: people who settle in a new country, such as Australia's skilled and family migration intake.
- Temporary migration: workers on fixed visas, seasonal labourers and working-holiday makers.
- Forced migration: refugees and asylum seekers fleeing persecution, conflict or disaster, who do not move freely.
- International students: a large education-driven flow that is temporary but economically significant.
- Tourism: short-term movement that is not migration but is a major flow of people.
A migrant chooses to move, usually for work or family. A refugee has fled their country and been recognised as needing protection under the 1951 Refugee Convention. An asylum seeker has applied for protection but has not yet had their claim decided. Using these terms accurately is essential in WACE responses.
Push and pull factors
Migration is usually explained as the interaction of push factors (conditions driving people away from a source) and pull factors (conditions attracting them to a destination), filtered by intervening obstacles such as cost, distance, border controls and visa rules.
- Push factors: unemployment, low wages, conflict and persecution, environmental hazards and drought, lack of services, political instability.
- Pull factors: job opportunities, higher wages, safety and political stability, family reunion, better healthcare and education, established diaspora communities.
Established communities create chain migration, where earlier migrants attract relatives and others from the same source area, reinforcing existing flows.
Global patterns
Around 281 million people, roughly 3.6 percent of the world population, lived outside their country of birth in 2020 according to UN estimates. Major patterns include:
- South to North labour flows, for example Mexico and Central America to the United States, and North Africa and the Middle East to Europe.
- Regional flows to oil-rich Gulf states, where temporary migrant workers from South and Southeast Asia make up most of the workforce in countries such as the United Arab Emirates and Qatar.
- Forced displacement, with tens of millions displaced by conflicts including Syria, Ukraine and Afghanistan.
- Skilled migration to high-income countries including Australia, Canada and the United Kingdom.
Remittances are money sent home by migrants to their families. The World Bank estimated remittance flows to low and middle-income countries at over 600 billion US dollars in recent years, exceeding total foreign aid. For countries such as the Philippines, Nepal and parts of the Pacific, remittances are a major share of national income.
Consequences for source places
Source (origin) places experience both gains and losses.
- Benefits: remittance income, reduced pressure on local jobs, skills and capital brought home by returning migrants.
- Costs: brain drain, the loss of skilled workers such as doctors and engineers; an ageing population if young adults leave; family separation and social disruption.
Consequences for destination places
Destination places also see mixed effects.
- Benefits: filling labour and skill shortages, a younger workforce supporting ageing populations, cultural diversity, entrepreneurship and population growth.
- Costs: pressure on housing and services, potential downward pressure on some wages, and social or political tension where integration is poor.
The Syrian civil war from 2011 pushed millions from their homes (conflict and persecution as push factors). By 2015 large numbers sought safety in Europe, pulled by stability and economic opportunity. Germany accepted around one million asylum seekers, gaining a younger labour supply but facing short-term costs in housing, integration and political division. Neighbouring Turkey, Lebanon and Jordan hosted the largest numbers, placing severe strain on their services. This single flow shows forced migration, push and pull factors, intervening obstacles such as borders and sea crossings, and uneven consequences across many places.
A balanced answer notes that the same flow can benefit one group and disadvantage another, and that effects differ between source and destination, and between the short and long term.
Using "refugee", "migrant" and "asylum seeker" interchangeably. They have distinct legal meanings; mixing them loses marks.
- Listing factors without classifying them
- Always label factors as push or pull and link them to a named example.
- Ignoring the source country
- Many answers only discuss the destination. Consequences for the origin, especially brain drain and remittances, are equally examinable.
- Forgetting intervening obstacles
- Distance, cost, border policy and visas shape who actually moves, not just the push and pull factors.

WACE 2021-style12 marksAnalyse the causes and consequences of international migration for both source and destination places. Use a specific example.Show worked answer →
A 12 mark response needs classified causes, two-sided consequences, and a developed example.
Causes. Explain migration as the interaction of push factors in the source (unemployment, conflict, persecution, environmental hazard) and pull factors in the destination (jobs, higher wages, safety, family reunion), filtered by intervening obstacles such as cost, distance and visa rules.
Consequences for source places. Benefits include remittance income and skills brought home; costs include brain drain, an ageing population and family separation.
Consequences for destination places. Benefits include filled labour shortages, a younger workforce and diversity; costs include pressure on housing and services and potential social tension.
Example. Develop one flow, such as the Syrian refugee movement into Europe and neighbouring states, to show push and pull factors and uneven consequences. Markers reward classified factors, both ends of the flow, and accurate terminology.
WACE 2023-style6 marksDistinguish between a migrant, a refugee and an asylum seeker, and explain why the distinction matters in geography.Show worked answer →
A 6 mark response needs accurate definitions and the significance of the distinction.
Definitions. A migrant generally chooses to move, usually for work or family. A refugee has fled their country and been recognised as needing protection under the 1951 Refugee Convention. An asylum seeker has applied for protection but has not yet had their claim decided.
Why it matters. The terms carry different legal rights and obligations: refugees are entitled to protection, asylum seekers to have claims assessed, while voluntary migrants are subject to ordinary immigration rules. Confusing them distorts analysis of forced versus voluntary movement and the responsibilities of destination states.
Markers reward the three precise definitions and a clear statement of why the legal distinction shapes geographical and policy analysis.
