  1. Analyzing a Population Pyramid:
    • Identify the y-axis (Age Cohorts) and x-axis (population size).
    • Examine the distribution of males and females.
    • Calculate the Sex Ratio to understand gender balance.
    • Determine the age cohort distribution (pre-reproductive, reproductive, post-reproductive) to assess growth potential.
    • Calculate the overall dependency ratio and its components (child and elderly Dependency Ratios) for insights into societal support needs.
  2. Using Population Data:
    • National governments should adjust services in response to demographic changes.
