AP Human Geography Vocabulary 1

A comprehensive set of vocabulary flashcards covering key geographical concepts, including environmental theories, regional classifications, types of diffusion, population metrics, and migration factors based on the lecture notes.

Environmental Determinism

The theory that the physical environment (climate, terrain) strictly shapes human culture and societal development.

Possibilism

The theory that while the physical environment sets limits, humans have the ability to adapt and choose cultural outcomes.

Formal Region

Functional (Nodal) Region

An area organized around a central focal point or node, connected by transportation or communication lines.

Vernacular (Perceptual) Region

An area that exists in people's minds based on informal cultural identity rather than strict scientific boundaries.

Relocation Diffusion

The spread of an idea or cultural trait through the physical movement of people from one place another.

Contagious Diffusion

The rapid, widespread diffusion of a characteristic throughout a population, like a viral wave.

Hierarchical Diffusion

The spread of an idea from authority figures or urban hubs down to lower-status groups or smaller locations.

Stimulus Diffusion

The spread of an underlying principle even though a specific characteristic fails to diffuse due to cultural barriers.

Distance Decay

The diminishing importance and eventual disappearance of a phenomenon as the distance from its origin increases.

Time-Space Compression

The reduction in time it takes for something to reach another place due to modern technology and transportation.

Arithmetic Density

The total number of people divided by the total land area.

Physiological Density

The total number of people divided by the amount of arable (farmable) land.

Agricultural Density

The ratio of the number of farmers to the total amount of arable land.

Malthusian Theory

The theory that human population grows exponentially while food production grows arithmetically, leading to inevitable starvation.

Rate of Natural Increase (RNI)

The percentage by which a population grows or declines annually, calculated as $\frac{(\text{Crude Birth Rate} - \text{Crude Death Rate})}{10}$.

Pronatalist Policy

Government policies designed to encourage citizens to have more children to increase fertility rates.

Antinatalist Policy

Government policies designed to discourage citizens from having children to limit population growth.

Push Factor

Negative conditions that compel people to leave their home region, such as war, political persecution, or economic collapse.

Pull Factor

Positive conditions that attract migrants to a new destination location, such as abundant job opportunities or political stability.
