AP Human Geography: Population Distribution, Density, and Demographics

Vocabulary flashcards covering human population distribution, density measures, population pyramid analysis, DTM stages, and demographic calculations.

Physical Factors of Population Distribution

Four environmental conditions that determine where humans settle: climate, landforms, soil quality, and water availability.

Arithmetic Density

A population measure calculated as total population divided by total land area.

Physiological Density

A population measure calculated as total population divided by arable land area.

Agricultural Density

A population measure calculated as total farmers divided by arable land area.

Egypt's Physiological Density

A high population concentration relative to arable land resulting from a large population living along the Nile River.

Agricultural Density in More Developed Countries

A lower agricultural density found in developed nations due to technological advances reducing the number of farmers needed for arable land.

Carrying Capacity

The maximum population an environment can sustain.

Country A (Population Pyramid)

A population pyramid profile corresponding to Stage $3$ of the Demographic Transition Model (DTM).

Country B (Population Pyramid)

A population pyramid profile corresponding to Stage $4$ of the Demographic Transition Model (DTM), characterized by not having enough workers.

Country C (Population Pyramid)

A population pyramid profile corresponding to Stage $5$ of the Demographic Transition Model (DTM), which exhibits the lowest Total Fertility Rate (TFR).

Country D (Population Pyramid)

A population pyramid profile corresponding to Stage $2$ of the Demographic Transition Model (DTM), which faces heavy strain on care for youth in the future.

Natural Increase Rate (NIR)

The percentage growth rate of a population, calculated as crude birth rate minus crude death rate divided by $10$ ($\frac{\text{CBR} - \text{CDR}}{10}$).
