I teach IGCSE Geography at an international school in Southeast Asia. World population growth was one of my best-selling lessons, but the headline story genuinely changed: the growth rate peaked in 1963 and the UN now expects the total to peak this century. So I rebuilt it from scratch for 2026, with the curve redrawn to 2100 and every indicator re-verified. If you bought the original, the update is free, just re-download.

What’s in it:
A complete, ready-to-teach lesson answering one big question: how did humanity grow so fast, and what happens next? You get a full PowerPoint presentation with answers included throughout (a big population quiz, a 1750 to 2100 curve-plotting task, exponential growth and doubling time, a kinaesthetic “Human Graph” activity, the ten-indicator demographer’s toolbox using Japan and The Gambia, the population equation, three true-or-false data graphs, a “baby bust” case study, and Tic Tac Toe review games), a Word workbook in three versions (Full colour, printer-friendly black and white, 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:

• How world population has grown from 1750, with projections to 2100
• Exponential growth and doubling time
• The difference between the growth rate and the total, and why both matter
• The key population indicators, including birth and death rate
• Natural increase, migration and the population equation
• How to interpret population data graphs and describe trends

Every figure is re-verified for 2026 against UN data, including a projected peak of about 10.3 billion. Also suitable for AP Human Geography, World Geography, and any population, demography 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: /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.
