This topic unpacks the human stories behind the demographic data, exploring why people undertake life-changing journeys and how this movement reshapes the world we live in.

Push vs. Pull Factor Card Sort

In pairs, students receive a set of cards detailing various reasons for moving (e.g., 'war', 'better job opportunities', 'access to university', 'famine'). They must sort these cards into categories: 'Push Factors', 'Pull Factors', or a middle column for factors that could be both, justifying their choices.

Identify the key features of a population pyramid for a country with a youthful population.

Facilitation Tip

Encourage discussion around ambiguous factors, like family, which can act as both a push and a pull.

What to look for

An exit ticket task: Students are given a mini case study of a migrant and must identify one push factor, one pull factor, and one likely impact on the host country's population pyramid.

Population Pyramid Detective

Provide groups with several unlabelled population pyramids from different countries (e.g., UAE, Japan, Mexico). Groups must analyse the shapes to deduce the migration story of each country, looking for evidence like bulges in working-age cohorts or skewed gender ratios.

Compare the population pyramids of Japan (an ageing population) and Nigeria (a youthful population).

Facilitation Tip

Provide a checklist of key features to look for, such as a narrow base, wide top, or specific bulges.

What to look for

Students select a specific migration route (e.g., Mexico to USA) and produce an extended piece of writing or presentation analysing the causes, consequences for people and places, and the evidence seen in population data.

A Tale of Two Journeys

Students read two short, anonymised case studies: one of a refugee and one of an economic migrant. They then complete a Venn diagram to compare and contrast the motivations, journeys, and challenges faced by each individual.

Explain the social and economic challenges a country with a high dependency ratio might face.

Facilitation Tip

Use a think-pair-share activity afterwards to discuss findings and sensitively address the stark differences in choice and circumstance.

What to look for

Provide students with a model annotated population pyramid. They use a traffic light system (red, amber, green) to rate their own confidence in identifying features related to birth rates, death rates, and migration.

Impacts on the UK: A Debate

Divide the class to debate the motion: 'This house believes that international migration has had a net positive impact on the UK'. Students research and prepare arguments focusing on economic, social, and cultural impacts, using specific evidence.

Identify the key features of a population pyramid for a country with a youthful population.

Facilitation Tip

Assign specific roles (e.g., opening speaker, rebuttal, summariser) to ensure broad participation and structured argument.

What to look for

An exit ticket task: Students are given a mini case study of a migrant and must identify one push factor, one pull factor, and one likely impact on the host country's population pyramid.

A few notes on teaching this unit

Start by grounding the abstract concepts of 'push' and 'pull' factors in students' own experiences before scaling up to international examples. Use a variety of case studies to avoid stereotypes and show the diversity of migrant experiences. Consistently link back to population pyramids, asking 'How would this event affect the pyramid?' to reinforce the connection between process and representation.

By the end of this topic, students will be able to confidently explain the causes and consequences of migration and link these processes to the shapes of population pyramids.

Watch Out for These Misconceptions

• All migrants are poor and move for purely economic reasons.

  Migration is a complex process driven by many factors, including education, family, safety, and environmental change, not just economics. Migrants come from all socioeconomic backgrounds.

• Refugees, asylum seekers, and economic migrants are all the same.

  These terms have distinct legal and practical meanings. A refugee is forced to flee due to persecution or violence. An economic migrant chooses to move for work. An asylum seeker is someone awaiting a legal decision on their refugee claim. The key difference is compulsion versus choice.

• When people migrate to a country, it only affects the host country.

  Migration has significant impacts on the source country as well. These can include receiving remittances (money sent home by migrants) but also suffering from 'brain drain', where skilled or educated workers leave.
