What this dot point is asking
Edexcel wants you to know why people migrate to the UK, the different types of migrant, the social and economic effects of immigration, and the main sources of migration from 1945 to the present. This Theme A topic (Paper 1 Section A, and often the source-based debates in Section D) is tested through "Explain" tasks on reasons and effects and through 12-mark, source-based "evaluate" questions on whether immigration is more of a benefit or a challenge. The examiner rewards accurate categories of migrant, a balanced grasp of effects, and the ability to use a source to support a reasoned, neutral judgement.
Types of migrant and why people migrate
People migrate for "push" and "pull" reasons. Push factors drive people away from where they live, such as war, persecution, poverty or lack of opportunity. Pull factors attract people to the UK, such as jobs, higher wages, safety, education, the English language and existing family or community links. Edexcel expects you to distinguish the categories clearly: an economic migrant who chooses to come for work is in a different legal and moral position from a refugee who has no safe choice but to flee. Confusing these categories is a common and costly error.
Sources of migration since 1945
After the Second World War the UK needed workers to help rebuild the economy and staff new services such as the NHS, and people were invited from Commonwealth countries; the arrival of the ship Empire Windrush in 1948 is often used to mark the start of large-scale post-war Caribbean migration. Later decades saw migration from South Asia and elsewhere. When several Central and Eastern European countries joined the EU in 2004, free movement brought significant migration from countries such as Poland. Since Brexit, EU citizens no longer have an automatic right to come to live and work in the UK, and migration is governed by a points-based immigration system. Knowing this rough timeline lets you ground answers in real history rather than generalisations.
The effects of immigration
The economic benefits are substantial: migrants often fill shortages in sectors such as health, social care, agriculture and construction, and as workers and consumers they contribute to growth and to tax revenue. Culturally, migration has shaped food, music, language, religion and everyday life, making the UK a diverse, multicultural society. The challenges are mostly about pace and place: a rapid rise in population in a particular area can strain housing, GP surgeries and school places in the short term, and there are genuine debates about integration and community cohesion. Edexcel's source-based questions ask you to weigh these benefits and challenges fairly, using evidence rather than assertion, and to remain politically neutral.
Exam-style practice questions
Practice questions written in the style of Pearson Edexcel exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
Edexcel 20184 marksExplain one reason why people migrate to the UK and one reason why migration can be seen as a benefit.Show worked answer →
A Paper 1 Section A "Explain" task (AO1 and AO2). Develop one reason for migrating and one benefit.
Reason to migrate: many people come for economic reasons, to take up work and earn a better living than they could at home; others come as refugees fleeing war or persecution, or to join family.
Benefit: migration can be a benefit because migrants fill skills shortages, for example in the NHS and social care, pay taxes and contribute to the economy and to cultural life.
Markers reward a developed reason and a developed benefit, each explained rather than just named.
Edexcel 202212 marksSource-based: using the source and your own knowledge, evaluate the view that immigration brings more benefits than challenges to the UK. (12)Show worked answer →
A Paper 1 Section D 12-mark evaluation (AO3, source-based). Use the source plus your own knowledge to argue both sides and judge.
For benefits: migrants fill skills shortages (for example in health and care), pay tax, start businesses and enrich culture; the source may show evidence of economic contribution.
For challenges: rapid migration can put short-term pressure on housing, school places and public services in some areas, and raises concerns about integration and competition for jobs.
Judgement: weigh the evidence, refer to the source explicitly, and reach a supported conclusion, for example that the long-term economic and cultural benefits are significant but that pressures are real and need managing through investment in services. Markers reward use of the source, balance and a substantiated judgement.
