    • This causes problems for the UK government:
          • some local councils have high numbers of elderly people, because many people move to England’s warm southerly coasts when they retire (e.g. Bournemouth)
          • the high cost of providing long term, expensive healthcare for some elderly people
          • the elderly are retired and unlikely to work again, so they will be a permanent and increasing financial strain on the economically active
          • there is an increasing demand for certain facilities such as public transport and sheltered housing
          • The UK’s population could stop growing or decline which makes the problem worse because there will be fewer and fewer economically active people
          • the burden of these extra costs will fall on the economically active population who will pay higher taxes and higher pension contributions
    AN AGING POPULATION
  • 10.
    • This causes problems for the Indian government:
          • the high cost of providing basic healthcare and education for so many young people.
          • a population explosion will happen when this youthful population matures and have their own families .
          • there is an increasing demand for basics such as housing, food etc.
          • the burden of these extra costs will fall on the economically active population.
    A YOUTHFUL POPULATION
  • 11. Model 2: The PPM (Population Pyramid Model) The PPM - 'Population Pyramid Model' shows how dynamic (subject to change) population is. The model is structured to show 'snapshots' of a population at four points during its development, which are shown as Stages 1 - 4 (A - D). A country will progress through the stages.
