AP Human Geography: The 12 Models You'll See on Every Exam

# AP Human Geography: The 12 Models You'll See on Every Exam

AP Human Geography has a 5-rate around 12-15%. It's often a student's first AP, taken in 9th or 10th grade. The exam tests your ability to apply geographic models to real-world situations — not just recall them.

Exam Structure

2 hours 15 minutes: 60 MCQs (60 min) and 3 FRQs (75 min). The FRQs typically ask you to define a concept, provide a real-world example, and explain a spatial pattern or geographic process.

The 12 Essential Models

Population & Migration:

**Demographic Transition Model (DTM)** — 4 stages from high birth/death rates to low both. Know which countries are in each stage and WHY.

**Epidemiological Transition Model** — Disease patterns shift from infectious to degenerative as countries develop.

**Ravenstein's Laws of Migration** — Most migrants move short distances, long-distance migrants go to major cities, every migration stream produces a counterstream.

Agriculture & Development:

**Von Thünen Model** — Concentric rings of agricultural land use around a central market. Perishable goods closest, extensive farming farthest.

**Rostow's Stages of Economic Growth** — 5 stages from traditional society to high mass consumption. Criticized as Western-centric.

**Wallerstein's World-Systems Theory** — Core, semi-periphery, periphery. Explains global economic inequality as structural, not just developmental.

Urban Geography:

**Burgess Concentric Zone Model** — City grows outward in rings from CBD.

**Hoyt Sector Model** — Growth follows transportation corridors in wedge-shaped sectors.

**Harris-Ullman Multiple Nuclei Model** — City has multiple centers of activity, not just one CBD.

**Galactic/Edge City Model** — Suburban growth around highway interchanges, far from traditional CBD.

Cultural Geography:

**Zelinsky's Migration Transition** — Migration patterns change with stages of demographic transition.

**Hagerstrand's Diffusion Theory** — Innovations spread from hearths through hierarchical, contagious, stimulus, and relocation diffusion.

The Application Strategy

Every FRQ asks you to APPLY models, not just recite them. For each model, prepare:

One real-world example that fits the model

One real-world example that DOESN'T fit (limitations)

Why the model might not apply in a specific context

**Drill**: Pick a city you know (your hometown works). Apply all four urban models to it. Which one best explains its spatial layout? Why do the others fall short? This type of critical analysis is exactly what the FRQ rewards.
