  • Overpopulation, underpopulation and optimum population
    • Population Density
      • Number of people in an area.
      • Density of a population = total population of a country (or area) / total area of that country (or area.)
    • Overpopulation
      • Too many people in an area relative to the amount of resources and technology available to maintain a high standard of living.
      • Implies that with no change in the level of resources, if population reduced, living standards would increase.
      • The density of people need not be high if the level of technology or natural resources is low.
      • Characterised by low GDP per Capita, high unemployment, high underemployment and out migration.
    • Underpopulation
      • Too few people in an area to use the resources effectively for a given level of technology.
      • An increase in population would mean a more effective use of resources and an increased living standard for all people
      • Characterised by high (but not maximum) per capita incomes, low unemployment and inward migration.
    • Optimum population
      • Theoretical population which, working with all available resources, will provide the highest standard of living for the people.
      • A dynamic concept: When technology improves, new resources become available which means even more people can be supported.
