GEO CT Prep - Settlement Patterns and Demographics

Settlement Patterns

  • Dispersed Settlement Pattern: Buildings, farms, and dwellings are spread out across a large area rather than grouped together.

  • Linear Settlement Pattern: Buildings and structures are built in a line, frequently following a physical feature or transport route such as a road, river, or valley.

  • Nucleated Settlement Pattern: Buildings and houses are clustered together tightly around a central point, such as a crossroads, market square, or freshwater source.

Factors Useful to Establish a New Settlement

  • Water Supply:

    • Sources: A nearby river, lake, or freshwater spring providing clean water.

    • Daily Survival: Essential for drinking and cooking. Humans cannot live for more than a few days without water.

    • Basic Hygiene: Access to water helps people stay clean, which stops diseases from spreading throughout the population.

  • Fertile Land:

    • Food Production: Rich, fertile soil allows settlers to farm crops and feed the entire community.

    • Animal Grazing: Good land provides grass and pasture for livestock and farm animals.

    • Long-term Growth: A reliable and continuous food supply allows the settlement to grow and become permanent.

  • Natural Resources:

    • Building Materials: Nearby forests supply wood, while local rock qualities and quarries provide stone to build strong, durable homes.

    • Fuel and Access to Energy: Wood, coal, or fast-flowing water provide power and fuel for heating, cooking, and running tools.

    • Trade Items: Valuable raw materials like salt, iron ore, or precious metals can be extracted and traded with other towns to build economic wealth.

PQE Analysis Framework

  • P - Pattern: Look for geographical features, spatial arrangements, or data trends that stand out or form identifiable patterns.

  • Q - Quantify: Add specific, accurate numerical information, data, or measurements to help explain and substantiate the observed pattern.

  • E - Exception: Identify and acknowledge anything that does not fit with the main pattern previously identified.

Population Density and Population Distribution

  • Population Density: The specific number of individuals living within a defined unit of area.

  • Population Distribution: The spatial pattern showing where people or organisms are spread out across a specific geographic area.

Population Pyramids and Demographic Stages

  • Population Pyramid Structure:

    • Displays demographic age cohorts divided into male and female populations across specific age bands (e.g., 4−54-5 or 7−87-8).

  • Stage 1:

    • Shape: Features a wide base and a tall, narrow top.

    • Birth Rate: High and steady.

    • Death Rate: High and steady.

  • Stage 2:

    • Birth Rate: High.

    • Death Rate: Lowering / rapidly decreasing.

  • Stage 3:

    • Birth Rate: Low / declining.

    • Death Rate: Low.

  • Stage 4:

    • Birth Rate: Low.

    • Death Rate: Low.

  • Stage 5:

    • Shape: Wide and tall at the top, reflecting an aging population with low birth and death rates.
