Geographical Factor in AP Human Geography

First came farming: climate and land set the options

The oldest geographical factors are physical ones. Topic 5.1 (Introduction to Agriculture) asks you to explain how a place's physical geography connects to the farming practiced there. Mediterranean climates have hot, dry summers and mild, wet winters, which suit crops like grapes and olives. Tropical climates support plantation agriculture and shifting cultivation.

The trap here is environmental determinism, the discredited idea that the environment dictates what a society becomes. AP Human Geography uses possibilism instead. The environment creates limits and opportunities, and people choose how to respond with technology and culture. Irrigation in a desert is a human response to a physical factor.

So write "the dry summers influence which crops farmers grow." Avoid writing "the climate forced this society to be agricultural." Don't use environmental determinism as an explanation of a cultural pattern, but recognize it if a question asks you to identify the theory.

Then came cities: site and situation pick the spot

The term does its main work in Unit 6, Topic 6.1 (The Origin and Influences of Urbanization), which asks what starts urbanization and what keeps it going. The first explanation the course gives is that a city's site and situation shape where it began, what it does, and how it grows.

Site factors are the physical traits of the spot itself, like a natural harbor, flat land, or a river crossing. Early cities in Mesopotamia grew on farmland between the Tigris and Euphrates rivers. Situation factors describe a place's connections to other places. Chicago grew because it sat where Great Lakes shipping met the rail network.

This is where a Question 2 (one-stimulus) or Question 3 (two-stimuli) answer earns or loses points. If a map shows a city on a coast, saying "its geography was good" is too vague to earn credit. Name the factor, such as access to coastal trade (or a deepwater harbor, if the stimulus actually identifies one). Then link it to the outcome with a because-statement (it let the city become a port for trade, which drew jobs and migrants). Only claim features the stimulus supports. Know whether your factor is site or situation, since a prompt may ask for one specifically.

Next came industry: coal, iron, and the hunt for more

Topic 7.1 (The Industrial Revolution) adds resources to the list. Industrialization started with new technologies, and Britain's coal and iron deposits helped it industrialize first. Factories clustered near those resources, and workers left farms for industrial jobs in cities. That links back to Unit 6, since industry pulled urbanization forward.

Resources can run out or fall short, and that changes the factors in play. Industrial investors went looking for more raw materials and new markets, which helped drive colonialism and imperialism. Topic 3.5 (Historical Causes of Diffusion) picks up the consequences. Colonial trade routes spread languages and religions, and they produced new cultural forms like creolization and lingua francas. A human factor (empire and trade) ended up shaping cultural patterns you can still map today.

Now: policy, migration, and growth in the periphery

Modern patterns often depend more on human factors than physical ones. Topic 6.1 lists transportation and communication changes, population growth, migration, economic development, and government policy as forces behind urbanization. Topic 2.7 (Population Policies) shows a government acting as a factor. Pronatalist, antinatalist, and immigration policies change a population's size and makeup.

Topic 6.2 (Cities Across the World) notes that megacities (over 10 million people) and metacities (over 20 million) are increasingly found in periphery and semiperiphery countries. Rapid population growth and rural-to-urban migration are the factors behind that shift. In the core, highways and cars help explain sprawl, edge cities, and boomburbs.

Factors also help draw regions in Topic 1.7 (Regional Analysis). A formal region can be defined by a shared physical trait like climate or a human one like a dominant crop. On a stimulus-based multiple-choice question, read the map or data first and decide whether the pattern traces back to a physical cause or a human one before picking an answer.
