Population structures

Developed country

A population pyramid showing the percentages of the people living in the UK

The population pyramid of the UK shows low birth and low death rates, and high life expectancy.

The effects of this population structure are as follows:

  • Too many elderly people, puts an added strain on services e.g. health care.
  • Extra money is required to build more care homes to accommodate elderly people.
  • The Government has to spend more money on pensions and less money elsewhere e.g. education.
  • Fewer children born means that less maternity hospitals and schools are needed.
  • Teachers and midwives are made redundant as they are surplus to requirements.
  • In the future, not enough people of working age are available to fill job vacancies.
  • The Government has to spend money recruiting foreign skilled workers to fill jobs.
  • People have to work longer as the age of retirement is raised.

Developing country

A population pyramid showing the percentages of the people living in India

The population pyramid of India shows high birth and death rates and low life expectancy.

The effects of this population structure are as follows:

  • Too many young people, puts an added strain on services e.g. health care.
  • Extra money is required to build more schools to accommodate children.
  • The Government has to spend more money on education and less money elsewhere e.g. industrial development.
  • More children born means that more maternity hospitals and schools are needed.
  • More teachers and midwives are required to be trained.
  • In the future, too many people of working age to fill job vacancies.
  • Unemployment and poverty increase.
  • Not enough homes, so shanty towns increase.
