FrançaisUnit 2: Population and Migration Patterns and Processes
Eight lessons covering all 12 College Board CED topics for AP Human Geography Unit 2. Where people live, why birth rates fall, what migration does to sending and receiving countries, and how to read every chart on the AP exam.
The 8 lessons in order
Population Distribution and Density
Where people live and why — physical and human factors driving the four global population concentrations.
Population Composition: Pyramids and Ratios
How to read population pyramids; sex ratio, dependency ratio, and what they tell us about a country's future.
Population Dynamics: Birth, Death, and Growth
CBR, CDR, TFR, IMR, NIR, doubling time — the demographic vocabulary every AP HG student must master.
The Demographic Transition Model
The five stages of the DTM, country examples for each stage, and the controversies of applying a single model to every nation.
Malthus, Population, and the Future
Thomas Malthus, his critics (Boserup, neo-Malthusians, Esther Boserup, Julian Simon), and the modern debate over carrying capacity.
Population Policies, Women's Status, and Aging Societies
Pro-natalist France, anti-natalist China, the link between female education and fertility, and the economic implications of an aging Japan.
Causes of Migration: Push, Pull, and Ravenstein's Laws
Why people leave home — economic, political, environmental, and family-level forces, and the difference between forced and voluntary migration.
Effects of Migration on Origin and Destination Countries
Brain drain, remittances, demographic dilution, cultural backlash — how migration reshapes both ends of the journey.
