Key Components of Population Composition

Age Structure

• The distribution of a population across different age groups.
• Categories:

  • Working Age (15-59 years): Economically active population.
  • Elderly (60+ years): Dependent population.
• Age-Sex Pyramid:
  • A graphical representation of age and sex distribution.
  • Types of Pyramids:
    1. Expanding Pyramid: Broad base, indicating high birth rates (e.g., Nigeria).
    2. Stable Pyramid: Uniform shape, indicating stable birth and death rates (e.g., USA).
    3. Contracting Pyramid: Narrow base, indicating low birth rates (e.g., Japan).
• Examples:
  • India has a broad-based pyramid, indicating a young population.
  • Japan has a narrow base, indicating an aging population.

Sex Ratio

• The number of females per 1,000 males in a population.
• Global Trends:
