Unit 2: Population And Migration


In this unit, we will explore key concepts such as population growth, demographic transition models, and the impact of migration on societies.


Topic: 2.1 Population Distribution and Density


Demography: The study of population; demographics

Ecumene: The part of the earth where humans have occupied a piece of land.


PHYSICAL factors that affect population distribution

    Climate: Too hot, Too cold

    Landforms: Desert, Rainforest, Mountains

    Bodies of Water


HUMAN factors that affect population distribution

    Culture

    Economics

    History

    Politics

    Migration


Arithmetic/Population Density: The number of people per unit area of land.

    ex: 1000 people living in one area

Physiological Popluation Density: the number of people per unit area of arable (agriculturallly productive) land.

    ex: Egypt does’nt have much arable land which can decrease the population

Agricultural Density: Number of farmers per unit of arable land. Generally lower agriculture densities = more developed countries.

    ex: Core countries like USA can be less agriculturale densities


Population Distribution and regioonal Clusters: These are clusters that represent the population clusters.

        Easter North America

        Easter South America

        East Australia

        Tropical/Subharan Africa

        Europe

        South Asia
