In recent years, the topic of migration in IB Geography— especially forced migration and human trafficking — has appeared more frequently in exams. What used to be a sub-topic is now a common feature.
Everything sub topic I’m covering below you can find in the full population revision pack available. It cuts out unnecessary theory and focuses tightly on the syllabus points, real case studies, and writing structures you need to understand to get your 7s in IB Geography.
Voluntary vs Forced Migration: Know the Difference
Voluntary migration happens when people choose to move for reasons such as job opportunities, education, or improved quality of life. These are known as pull factors.
On the other hand, forced migration is driven by push factors, including war, persecution, environmental disasters, or trafficking. It’s important in IB answers to define the type of migration clearly and link it to relevant drivers and obstacles.
For example, war refugees are considered forced migrants due to armed conflict and political instability in their home country. In contrast, Indian IT professionals moving to the United States are voluntary migrants, driven by employment opportunities and higher wages.

Impacts of Migration on Host and Home Countries
Migration produces both positive and negative outcomes for host and origin countries.
For host countries, the positive impacts often include an increase in workforce, economic stimulation, and greater cultural diversity. However, these benefits can be offset by added pressure on public services, increased housing demand, and rising social tensions.
In the origin country, one major benefit is remittances sent home by migrants, which support families and boost local economies. Migration can also ease unemployment. But negative effects include the loss of skilled labour (commonly referred to as brain drain) and an ageing population that lacks enough working-age adults to support economic growth.
A clear example of this is the movement of Polish workers to the UK during the period of open EU migration. Poland experienced a shortage of young skilled workers, while the UK gained economically but saw increased pressure on housing and public infrastructure.
Barriers to Leaving: Not Everyone Can Migrate
While many discussions around migration focus on why people move, it’s equally important to understand why some people can’t. Migration decisions are often constrained by physical, economic, legal, and social barriers.
Physical barriers include geographic obstacles like mountains, oceans, or militarized borders. While of course, economic limitations involve the inability to afford travel, legal documents, or smuggling fees.
Legal barriers are also crucial. Countries may have strict visa laws, caps on asylum claims, or detention policies that prevent entry. Just this September 2025, Bloomberg reported that “the US will use this year’s gathering of the United Nations General Assembly to push other countries to adopt more restrictions on asylum.”
Social and psychological barriers — like family ties, fear of the unknown, or lack of migrant networks — also play a significant role in limiting mobility. These are all factors affecting mobility, directly mentioned in the IB syllabus and commonly tested.
Human Trafficking: A Form of Forced Migration
Human trafficking is a severe form of forced migration, often involving deception, coercion, and abuse. Victims are typically moved across borders or within countries and exploited for purposes such as forced labour (Vietnamese to the UK’s cannabis fields), sexual exploitation (African women trafficked to Europe), promised jobs but found themselves trapped in brothels. This issue is increasingly appearing in IB exams, especially in Paper 1 for HL students.
Prevention strategies include international cooperation led by organisations with the INTERPOL, tougher national laws and penalties, and support services for victims. Notes include these examples.
Recent Anti-Migration Movements
In 2025, migration isn’t just a geographic or economic issue — it’s a major political flashpoint, seen in how the United States plans to use the United Nations General Assembly to push for tougher asylum laws. This move signals growing international resistance to open-border policies.
At the same time, over 100,000 people marched in London and (fewer) in Sydney to protest new anti-migration laws and detention practices. These examples are highly useful in your Paper 1 conclusion or evaluation sections. They demonstrate real-world tensions and show that you’re aware of the dynamic nature of migration policies, a key IB expectation.
If I have the time I may do up a bit about the recent anti-migration waves (100,000 taking to the streets in London, with the same happening in Australia).
Ways to Reduce Tension Between Migrants and Host Communities
As migration increases, so does the risk of cultural and political tension. However, there are some methods governments can use to promote social cohesion. These include language and cultural integration programs, anti-discrimination laws, and community outreach. Public education campaigns can also help reduce xenophobia and misinformation.
Final Writing Tips for IB Geography Students
To reach a level 7, structure your answers clearly. Start with clear definitions. Use real-life, specific case studies. Refer directly to the IB syllabus terms like migration, push/pull factors, forced migration, trafficking, remittances, mobility, and barriers. Use evaluative phrases where appropriate, and always connect the case study back to the question asked.
