Master AP® Human Geography from first principles
AP Human Geography exam preparation — 7 CED units, MCQ + FRQ practice modeled after the official exam format.
Unit 1.1 — The Five Themes of Geography
The five-theme framework (location, place, human-environment interaction, movement, region) that every later unit builds on — with the precise distinctions the exam tests.
Unit 1.2 — Location, Place, and Types of Regions
Site vs. situation, toponyms, and the three region types — formal, functional, and vernacular — with the evidence test the exam uses to tell them apart.
Unit 1.3 — Spatial Patterns, Distance Decay, and Diffusion
Clustered vs. dispersed patterns, distance decay, and the four diffusion types — relocation, contagious, hierarchical, and stimulus — with the scenario cues that identify each.
Unit 1.4 — Scale of Analysis and the Modifiable Areal Unit Problem
Why the same data can support different conclusions depending on the scale and boundaries used to group it, and the two components of MAUP the exam names directly.
Unit 1.5 — Human-Environment Interaction: Determinism vs. Possibilism
Why environmental determinism was discredited and how possibilism replaced it as the field's working model of environment, culture, and choice.
Unit 1.6 — Maps, Map Projections, and Geospatial Technology
How every flat map distorts the globe on purpose, the standard thematic map types, and how GPS, remote sensing, and GIS work together as the unit's closing lesson.
Unit 2.1 — Population Distribution and Density
Learn how geographers map where people live and measure crowding with arithmetic, physiological, and agricultural density — plus carrying capacity and the ecumene.
Unit 2.2 — Population Composition and Age-Sex Pyramids
Read age-sex pyramids like a geographer: expansive, stationary, and constrictive shapes, sex ratio, dependency ratio, and the demographic dividend.
Unit 2.3 — The Demographic Transition Model and the Epidemiological Transition
Walk through all five DTM stages and the paired epidemiological transition, with the CBR/CDR/RNI/doubling-time math the exam expects you to calculate.
Unit 2.4 — Malthusian Theory and Its Critiques
Malthus's 1798 warning, why it didn't play out as predicted, and the Boserup, Neo-Malthusian, and Cornucopian arguments that still shape this debate.
Unit 2.5 — Migration Causes and Types
Push-pull factors, Ravenstein's laws, and the forced/voluntary and internal/international distinctions that classify every migration scenario the exam gives you.
Unit 2.6 — Consequences of Migration for Origin and Destination
The Unit 2 closer: brain drain and remittances at home, labor-force gains and ethnic enclaves abroad, and how migration ties every earlier Unit 2 concept together.
Unit 3.1 — Culture, Cultural Landscapes, and Culture Regions
What culture actually means to a geographer, how it shows up as a visible cultural landscape, and the trait/complex/region toolkit used to map and compare it.
Unit 3.2 — Cultural Diffusion: Relocation, Contagious, Hierarchical, and Stimulus
How cultural traits actually spread across space, from migrants carrying an idea with them to a concept reinvented locally as it diffuses.
Unit 3.3 — Language Geography: Families, Dialects, and Lingua Francas
How languages are classified into families and branches, why the line between a dialect and a separate language is often political, and how trade languages and empires spread a language worldwide.
Unit 3.4 — Religion Geography: Universalizing and Ethnic Religions
Where the major world religions originated, the specific historical pathways each spread through, and how universalizing and ethnic religions differ in reach and diffusion.
Unit 3.5 — Ethnicity, Gender, and Identity in Geographic Perspective
How ethnicity differs from race and nationality, how ethnic enclaves and ghettos form, and how gender roles and layered identity show up as measurable spatial patterns.
Unit 3.6 — Popular vs. Folk Culture and the Effects of Globalization
The unit closer: how folk culture differs from mass-produced popular culture, and how globalization both erodes and, through glocalization, helps preserve local cultural distinctiveness.
Unit 4.1 — State, Nation, Nation-State, and Sovereignty
Political geography starts with precise vocabulary: what makes a territory a state, what a nation is, why nation-states are rare, and what sovereignty actually means.
Unit 4.2 — Boundary Types and Boundary Disputes
How political boundaries are drawn — physical, geometric, antecedent, superimposed, relic — and the four kinds of disputes that can break out once they exist.
Unit 4.3 — Unitary and Federal Governance, and Devolution
Why some states centralize power in one capital while others divide it constitutionally among regions, and how devolution lets a state redistribute power without breaking apart.
Unit 4.4 — Supranationalism: the EU, the UN, and NATO
Why sovereign states voluntarily pool authority into shared organizations, and how the EU, UN, NATO, and other bodies differ in depth and scope of shared power.
Unit 4.5 — Electoral Geography: Packing, Cracking, and Gerrymandering
How redrawing voting-district lines around the same voters can flip an election, and the packing and cracking techniques political geographers use to detect it.
Unit 4.6 — Geopolitics, Territoriality, and Centripetal/Centrifugal Forces
Unit 4 closer: the spatial logic of territorial control, classic geopolitical theories of state power, and the forces that hold states together or pull them apart.
Unit 5.1 — Origins and Diffusion of Agriculture; the First and Second Agricultural Revolutions
Where farming began, why it began in several places at once rather than one, and how two later revolutions in Britain reshaped how food reaches everyone else.
Unit 5.2 — Von Thünen's Model of Agricultural Land Use
A nineteenth-century German landowner's ring diagram still explains why dairy farms cluster near cities while cattle ranching sprawls across the far countryside.
Unit 5.3 — The Green Revolution and Its Consequences
How a mid-twentieth-century package of seeds, fertilizer, and irrigation nearly tripled global grain yields — and the costs that came with it.
Unit 5.4 — Agricultural Production Systems and Agribusiness
From swidden plots that feed one family to vertically integrated corporations that supply a continent — how geographers classify the world's farms and who profits from them.
Unit 5.5 — Rural Settlement Patterns and Land Survey Systems
Why some farm villages huddle together while others scatter across the land — and how three different land-survey systems still shape the shape of American farmland from above.
Unit 5.6 — Sustainability Challenges in Agriculture
Desertification, vanishing aquifers, and the GMO debate — how the unit's farming systems collide with environmental limits, and what it all adds up to for the exam.
Unit 6.1 — Urbanization: Processes and Patterns Worldwide
How geographers measure urbanization, why cities form and grow, and how the timing of industrialization produces very different urban growth stories across the world today.
Unit 6.2 — Models of Internal City Structure
The concentric zone, sector, and multiple nuclei models — who proposed each, when, and the mechanism each uses to explain where land use and wealth land inside a city.
Unit 6.3 — Urban Hierarchy, Central Place Theory, and Rank-Size vs. Primate Cities
How settlements sort by the services they offer, Christaller’s hexagon logic of threshold and range, and why some countries’ cities follow the rank-size rule while others develop a primate city.
Unit 6.4 — Urban Sustainability Challenges: Sprawl, Gentrification, Food Deserts, and Housing
Four recurring urban problems and the policy tools tied to each, from urban growth boundaries and New Urbanism to redlining’s legacy, grocery-threshold economics, and exclusionary zoning.
Unit 6.5 — World Cities and Globalization’s Effect on Urban Systems
What makes a city a world city, the GaWC alpha/beta/gamma ranking, and how globalization splits manufacturing and command functions across the global urban system.
Unit 6.6 — Synthesis: Comparing and Applying the City Structure Models
This unit closer lines up Burgess, Hoyt, and Harris/Ullman side by side, adds the regional variants that extend them, and walks through how to argue a model choice with evidence.
Unit 7.1 — Measuring Development: GDP/GNI, HDI, and the Gender Inequality Index
How geographers measure development — GDP vs. GNI per capita, PPP adjustment, the Human Development Index, and the Gender Inequality Index — and what each measure hides.
Unit 7.2 — Explaining Development: Rostow's Stages and Wallerstein's World Systems Theory
Two competing theories of why countries develop differently: Rostow's five-stage growth ladder and Wallerstein's core-periphery world systems model.
Unit 7.3 — The Industrial Revolution's Origins, Diffusion, and Weber's Least-Cost Location Theory
Why the Industrial Revolution began in Britain, how it diffused to Europe, the U.S., and Japan, and Weber's model for where factories locate.
Unit 7.4 — Deindustrialization, Outsourcing, Offshoring, and the Globalization of Production
The Rust Belt, the new international division of labor, special economic zones and maquiladoras, and the costs and benefits of globalized manufacturing.
Unit 7.5 — Sustainable Development: Resource Use, Pollution, E-Waste, and Microfinance
Renewable vs. nonrenewable resource depletion, industrial and consumption pollution, the global e-waste trade, and microfinance as a grassroots alternative.
Unit 7.6 — Course Synthesis: How Economic Development Connects Every Unit
The unit and course closer: how development theory ties back to population, migration, culture, political geography, agriculture, and urban patterns from Units 1–6.
