A ready-to-teach IB Geography lesson exploring Population Distribution and Economic Development at the National Scale, designed to help students understand why population, wealth, investment and opportunities become concentrated in particular regions of a country.

This engaging lesson develops students’ understanding of the core–periphery model, showing how physical advantages, economic investment, infrastructure and migration can create powerful national cores while other regions experience lower investment, population decline and increasing inequality.

Students explore the links between physical geography, path dependency, multiplier effects, internal migration, urbanisation, agglomeration and megacity growth, moving beyond simple description to analyse the processes that create uneven development.

The lesson uses a range of contrasting examples, including China, Nigeria, France, Italy, the UK and Poland, helping students apply geographical concepts across different national contexts. Contemporary statistics and case-study evidence are incorporated throughout, including data relating to China’s internal migrant workforce, regional GDP differences, urbanisation and global megacity growth.

Designed specifically with IB Geography skills and assessment expectations in mind, the resource encourages students to:

• Interpret and analyse geographical data
• Apply the core–periphery model to real-world examples
• Explain cause–process–consequence relationships
• Analyse internal migration and urbanisation
• Consider the role of physical and human factors in development
• Evaluate whether economic growth reduces or reinforces regional inequality
• Use appropriate geographical terminology and evaluation language
• Develop stronger IB exam responses

The lesson includes a combination of visual interpretation, discussion, collaborative decision-making, case-study analysis, data interpretation, geographical modelling and exam-style application, keeping students actively involved while progressively building towards higher-level evaluation.

Students are also encouraged to consider important geographical debates, including whether migration helps peripheral regions or drains them of young workers, whether GDP alone can define an economic core, and whether megacity growth acts as an engine of national development or reinforces inequality.

The resource concludes with IB-style 6-mark and 10-mark exam practice, clear success criteria and structured guidance to help students develop well-supported, evaluative answers.

Ideal for teachers looking for a modern, visually engaging and academically rigorous IB Geography lesson that combines strong geographical knowledge with the analytical, evaluative and data-handling skills required for success in the IB Diploma.
