  • Population Pyramids What They Mean

  • Population Pyramids What is it?

    Graphical illustration that shows the amount of people per age group within a country, and is usually in pyramid form when the population is growing.

  • Rapid Growth Populations

    1. Broad Base

    2. Basically even distribution between male and female

    3. High fertility rates

    4. Low average life expectancy

    5. Usually found in Less Developed or Newly Industrialized nations

  • Rapid Growth Populations

    Haiti 2016

  • Slow Growth Populations 1. Pyramid shape, with a smaller

    base

    2. Can easily fall back into rapid growth

    3. Declining fertility and mortality rates

    4. Beginnings of better education, medical, and working condition

    *Newly Industrialized

  • Bolivia-2016

  • Zero Population Growth 1. Shape is almost column like

    2. Population that is unchanging (not growing or shrinking)

    3. Birth Rate and Death Rate are equal

    4. Most commonly found in areas that have stable education, health care and government.

    5. Most often a More Developed country

  • Uruguay 2016

  • Negative Population Growth 1. Often an inverted triangle

    2. More deaths than births

    3. Caring for the elderly is hard

    4. Often ‘self imposed’ by high costs of living

    5. Can be due to natural events like famine or war

    6. Can cause long term problems for countries

  • Cuba- 2016

  • Stages of Population Change 1. 2.

    Rapid Growth Slow Growth

    3. 4.

    Stable Growth Negative Growth

  • Stages of Population Change

    1. As countries develop, they go from one stage to the next, or even back a step.

    2. Not all countries want a negative population, so they actively seek ways to maintain their healthy populations while not overpopulating.
