People of the Planet
This topic explores the uneven nature of global development, the causes of this disparity, and the factors influencing economic development in LIDCs and EDCs. It also covers the trends, causes, and consequences of rapid urbanisation, and the distinct challenges faced by cities in these contexts.

Quick Revision Summary (Key Takeaway)
People of the Planet explores global population distribution, growth, and migration, examining how physical and human factors shape where people live and the challenges of rapid urbanisation. It covers demographic transition, population policies, and sustainable development, linking to broader themes of global inequality and resource management.
Topic Overview
People of the Planet is a key topic in OCR GCSE Geography that explores the dynamic relationship between human populations and the environment. It covers where people live (distribution and density), why populations grow or decline (birth rates, death rates, migration), and the consequences of these changes. Understanding this topic is essential for grasping global issues like urbanisation, resource pressure, and sustainable development.
The topic is structured around three main themes: population dynamics (including the Demographic Transition Model and population pyramids), migration (types, causes, and impacts), and population policies (e.g., China's One-Child Policy, Singapore's pro-natalist policies). Case studies from different continents are used to illustrate concepts, such as the rapid growth in Nigeria and the aging population in Japan.
This topic connects to other parts of the GCSE course, such as 'Urban Futures' (urbanisation) and 'Resource Reliance' (food, water, energy). It also links to global citizenship and sustainability, helping students understand contemporary issues like refugee crises and the UN's Sustainable Development Goals. Mastering this topic requires memorising key terms, applying models to real-world data, and evaluating policies critically.
Key Concepts
Core ideas you must understand for this topic
- →Population distribution and density: how people are spread across the Earth and the number of people per unit area.
- →Demographic Transition Model (DTM): a model showing how population changes over time from high birth/death rates to low birth/death rates.
- →Population pyramids: graphical representations of age-sex structure used to analyse population characteristics.
- →Migration: movement of people, including push/pull factors, and types such as rural-urban, international, and forced migration.
- →Population policies: government strategies to influence population growth, such as anti-natalist (e.g., China) or pro-natalist (e.g., France).

Examiner Tips
Expert advice for maximising your marks
- 💡Ensure case studies are from the 21st century
- 💡Use specific examples to support arguments about development indicators
- 💡When discussing urbanisation, clearly distinguish between social, economic, and environmental consequences
- 💡Practice applying Rostow's model to your chosen LIDC/EDC case study to ensure you can justify its current stage
- 💡Use the glossary definitions provided in the specification to ensure accurate use of terminology
- 💡Ensure you can explain both the positive and negative impacts of aid on development.
- 💡Be prepared to link historical context, such as colonialism, to current patterns of uneven development.
- 💡Ensure the case study is a specific LIDC or EDC and that you have contextual knowledge of it.
- 💡Use specific examples of imports/exports and aid projects to support your arguments.
- 💡Practice linking social factors (education/healthcare) to economic outcomes.
- 💡Be prepared to evaluate the success or limitations of aid projects.
- 💡Ensure you can distinguish between push factors (e.g., lack of jobs, poor services) and pull factors (e.g., employment opportunities, better healthcare/education).
- 💡Remember that urbanisation is driven by both migration and natural increase (birth rate exceeding death rate).
- 💡Be prepared to discuss both positive and negative impacts across social, economic, and environmental dimensions.
- 💡Ensure the chosen city case study is from an LIDC or EDC as specified in the curriculum.
- 💡Link the city's growth and character explicitly to migration patterns.
- 💡When discussing sustainable strategies, evaluate their success rather than just describing them.
- 💡Use specific examples of ways of life (e.g., specific cultural practices or housing types) to support arguments.
- 💡Always use specific case study details (country names, dates, data) to support your points. Generic answers lose marks.
- 💡When evaluating, give both strengths and weaknesses before reaching a conclusion. Use phrases like 'on one hand... on the other hand...'.
- 💡Label diagrams clearly (e.g., population pyramids) and annotate them to show understanding of trends.
Common Mistakes
Pitfalls to avoid in your exam answers
- Confusing the definitions of AC, EDC, and LIDC
- Failing to evaluate the advantages and disadvantages of development indicators
- Over-generalising the causes of uneven development without specific reference to colonialism or trade
- Misapplying Rostow’s model to a country that does not fit the stages
- Confusing push and pull factors in the context of urbanisation
- Failing to link the chosen case study to the specific factors listed in the specification.
- Misapplying stages of Rostow's model to the chosen country.
- Describing factors in isolation rather than explaining their interrelationships.
- Using outdated case study data (must be 21st century).
- Misconception: 'Population density is the same as population distribution.' Correction: Density is a measure (people per km²), while distribution is the pattern (e.g., clustered).
- Misconception: 'The DTM applies to all countries equally.' Correction: The DTM is a generalised model; some countries skip stages or experience different rates of change due to unique factors.
- Misconception: 'All migration is from poor to rich countries.' Correction: Migration also occurs between developing countries (e.g., rural to urban) and between developed countries (e.g., EU freedom of movement).
