    • LDC’s
      What will the population of a country like this look like in the future?

      What will the population of a country like this look like in the future? This profile will continue but the bottom will be wider.
    • A country with this “pyramid-shaped population profile is in Phase II of Demographic Transition (Transitional Phase).
