Introduction

Lesson Overview

OBJECTIVES

Explain key population concepts: population density, distribution, demographics

Analyze population pyramids and what they reveal about a country's development

Identify push and pull factors that drive migration

Evaluate the impacts of migration on both sending and receiving countries

Apply the Demographic Transition Model to real-world countries

AP Human Geography Standards: Unit 2 — Population and Migration Patterns and Processes (12-17% of AP exam)

Essential Question

Why do people move, and how does population change shape the world?

Part 1 Population Vocabulary (15 min)

Teach key AP Human Geography terms

* Population Density Number of people per square mile/kilometer

* Population Distribution Where people are spread across Earth (clustered vs. dispersed)

* Demography The statistical study of human populations

* Crude Birth Rate (CBR) Live births per 1,000 people per year

* Crude Death Rate (CDR) Deaths per 1,000 people per year

* Rate of Natural Increase (RNI) CBR minus CDR (not including migration)

* Total Fertility Rate (TFR) Average number of children per woman

Part 2 Population Pyramid Analysis (20 min)

Show students three population pyramids

Pyramid 1 (Nigeria) Wide base — lots of young people, high birth rate, rapid growth

Pyramid 2 (United States) More even shape — moderate birth rate, aging population

Pyramid 3 (Japan) Narrow base — low birth rate, many elderly, population decline

Student Task In pairs, answer:

1. Which country has the highest birth rate? Lowest?

2. Which country will have the most working-age adults in 20 years?

3. Which country will have the highest healthcare costs in 20 years?

4. If you were a government leader in Japan, what policies would you suggest to address your country's population decline?

Phase 01

AP-Style Free Response Practice

Exit Ticket / FRQ Practice (10 minutes):

Choose ONE of the following AP-style questions and write a short response:

Option A: Describe TWO push factors that might cause someone to leave their home country and ONE pull factor that might attract them to the United States.

Option B: Explain how a country's population pyramid changes as it goes through the Demographic Transition Model. Use a specific country as an example.

Option C: Explain ONE positive and ONE negative impact of migration on the receiving country.

AP Rubric: A complete response defines the term, provides a specific example, and explains the connection.

Phase 02

Hook: The 7 Billion Question

Display this fact: 'In 1800, the world had 1 billion people. In 2023, we surpassed 8 billion.'

Ask students: If the world population keeps growing, what problems could arise? What solutions can you think of?

Show students a moment of silence representing each billion: 1 second per billion, 8 seconds total. Then explain that it took all of human history to reach 1 billion, but only 12 years to go from 7 to 8 billion.

Think-Pair-Share: Where is population growing the fastest? Where is it shrinking? Why do you think that is?

Phase 03

Migration: Push, Pull, and Everything Between

Student Activity Block

The Migration Decision Game

Give students 10 scenario cards. For each, they decide: Would this cause you to LEAVE a place (push factor) or ATTRACT you to a new place (pull factor)?

Scenarios:

1. War breaks out in your country (push)
2. A factory is hiring with good wages in a neighboring country (pull)
3. Drought destroys your family's farm (push)
4. Your country has free college education (pull)
5. Religious persecution in your community (push)
6. Your family already lives in another country (pull — chain migration)
7. Your country has no healthcare system (push)
8. A new law gives immigrants a path to citizenship (pull)
9. Environmental disaster floods your home (push — environmental refugee)
10. Your skills are needed in another country's economy (pull)

Discussion Question

Class Which push factors are most powerful? Which pull factors? How does this help us understand migration from Central America to the US? From Syria to Europe? From rural areas to cities?

AP Connection: Ravenstein's Laws of Migration — most migrants move short distances, long-distance migrants go to major economic centers, each migration flow produces a counter-flow, women migrate more within their country than internationally.
