The Demographic Transition Model | Complete Geography Lesson | Slides & Workbook

I teach IGCSE Geography at an international school in Southeast Asia. This was one of my best-selling lessons, but a model lesson lives or dies by its data - so I rebuilt it from scratch for 2026: the model redrawn, the real-country data refreshed, and Stage 5 covered for the countries now shrinking. If you bought the original, the update is free, just re-download.

What’s in it:
A complete, ready-to-teach lesson on the Demographic Transition Model, built around one big question: why do populations stop growing as countries get richer? You get a full PowerPoint presentation with answers included throughout (a “four countries, four stories” data starter with natural-increase calculations and The Gambia paradox, the five-stage model read line by line, a hinge question that kills the “stage 2 explodes because birth rates rise” misconception, a whiteboard showdown, The Living Graph stage-sorting task, a birth-rate/death-rate card sort, a case-for-and-against evaluation, and a real three-century dataset tested against the model), a Word workbook in four versions (Student-guided and Teacher-guided scaffolding, each in full colour and printer-friendly black and white, plus a ready-to-print PDF), and a 30-question Blooket quiz file for instant retrieval practice. Bonus access to free lesson-support activities and daily games on the Geography Oasis website.

What students learn:

• What the DTM shows and why demographers use it
• How birth rate, death rate and total population move through all five stages
• Why death rates fall first, then birth rates follow as a country develops
• How to calculate natural increase and read real population data
• How to evaluate the model - where it fits real countries and where it does not
• Why Stage 5 matters and some countries are now shrinking

The model is redrawn for 2026 and the real-world data section is refreshed to the latest available figures. Also suitable for AP Human Geography, World Geography, and any population, development or human geography unit at ages 11-16.

Format:
Delivered as fully editable PowerPoint (.pptx) and Word (.docx) files, plus PDF. Diagrams and visuals are not editable.

TEACHING CAMBRIDGE IGCSE GEOGRAPHY (0460)?
I have also rebuilt this whole topic as a complete Population & Migration unit for the 2027 syllabus: 7 modules with lesson slides, student workbooks, full answer keys and bonus interactive website access. Start with the free sample: https://www.tes.com/teaching-resource/resource-13453951

This is one of a growing collection of fully rebuilt 2026 geography lessons; more are on the way in my shop. If you find this useful, a review would mean a lot. It’s how other teachers discover these resources, and it helps me keep creating.
