AP Human Geography concepts & vocabulary — the master hub
AP Human Geography is a vocabulary exam at heart, and the models are where students gain or lose the most points. This hub indexes the highest-yield AP Human Geography vocabulary, from settlement models to population theory, each with a one-line definition and a link to a fuller guide.
How to use this hub
Skim the grouped terms below to find the models you cannot yet explain in a sentence. AP Human Geography rewards naming a model and applying it to a scenario, so each definition is written to be usable, not just memorized.
When a model is fuzzy, open its guide for the assumptions, the diagram, and the traps that cost students points on the exam.
Settlement & economic models
The models that explain where people, services, and farms locate.
Population & development
How population changes as a country develops.
Culture & diffusion
How ideas, people, and innovations spread across space.
How AP Human Geography tests models
Multiple-choice questions usually hand you a scenario, a map, or a graph and ask which model or term it demonstrates. Knowing a flashcard definition is not enough; you have to recognize the model in an unfamiliar setting.
The free-response questions reward applying a model to a specific place or situation. Practice writing one tight sentence that names the model and ties it to a concrete example.
Frequently asked questions
Quick answers, written by humans.
How much vocabulary does AP Human Geography have?
A lot. The course is built around models and terms, and most multiple-choice questions test whether you can recognize a concept in a scenario. Learning each term with an example is the highest-leverage thing you can do.
Which AP HuG models show up most?
Central place theory, the Von Thunen model, the demographic transition model, and the types of diffusion are among the most frequently tested. The migration and population units lean on them heavily.
What is the best way to memorize AP HuG models?
Pair each model with a real example and a quick sketch of its diagram. Recognizing the model in an unfamiliar place, which is what the exam asks, comes from examples, not bare definitions.
