Analyse the causes, patterns and consequences of international flows of people

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.

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.

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.

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.
