This topic explores the relationship between population and the environment, including the concept of carrying capacity and the different perspectives on the population-resource debate (e.g., Malthus and Boserup). It investigates the factors affecting population change, such as fertility, mortality, and migration, and the social, economic, and environmental consequences of population growth. The topic also examines the different policies that have been used to manage population change.
Board notes: A key topic for AQA, Edexcel, and OCR. AQA has a focus on the concept of environmental refugees. Edexcel requires students to have a detailed understanding of the causes and consequences of forced migration. OCR often includes questions on the relationship between population, health, and development.
Step-by-step explanationWorked example
When asked to 'compare the population policies of two countries', a student should choose two countries with contrasting policies, for example China's one-child policy and France's pro-natalist policy. They should describe the aims and methods of each policy, and evaluate their social, economic, and demographic impacts. The answer should conclude with a justified judgement on the overall success of each policy.
