  • Population Change RevisionBy Diane Stetcu

  • Key words

    Population the people living in an area

    Population distribution how people are spread out in a place

    Population density the number of people per square km (how crowed an area is)

    Densely populated more than 50 people per km (crowed)

    Sparsely populated less than 10 people per km

  • Why are areas DENSLEY populated?

    Flat land (easy to build on)

    Mild climate (easy to live in)

    Fertile soil

    Good education system

    Tourist attractions

    Good health care

    Job opportunities (more money)Easy access to

    river or sea

    Yellow = physical factors Orange = human factors

  • So, why are areas sparsely


  • Why are areas SPARSELY populated?

    Extreme climate; too hot or cold (difficult to live in)

    High relief (hard to access)

    Lack of water

    Poor/no education system

    No tourist attractions

    Poor health care

    No job opportunities


    Yellow = physical factors Orange = human factors

    Infertile soil

  • Factors that determine population change

    Infant mortality the number of babies per 1000 born that die before their first birthday.

    Immigrants a person who moves into an area or country.

    Birth rate the number of births per 1000 people in a year.

    Carrying capacity the maximum number of people that can be supported by the resources and technology of a given area.

    Death rate the number of deaths per 1000 people per year.

    Natural change the birth rate minus the death rate.

    Migration the long-term movement of people.

    Emigrants a person who moves out of an area or country.

  • Example of natural change

    Country Birth rate Death rate Rate of natural change

    Swaziland 27.0 30.4 -3.4

    Cambodia 25.5 8.2 17.3

    Chile 15.0 5.9 9.1

    UK 10.7 10.1 0.6

  • Why do birth and death rates vary as a country develops?Social

    Women are educated about contraception in HICs and would want to focus on their career.

    Also, couples will want smaller families.

    In LICs, they have less knowledge about maternity and women arent as likely to continue their education.


    In HICs, its expensive to bring up a child.

    186,032 to raise a child until theyre 21.

    In LICs, children are considered a financial asset.

    In HICs, children are considered a financial burden.


    HICs continuously have now treatments for diseases.

    LICs struggle, with people dying from simple diseases.


    China have introduced the One Child Policy to reduce the birth rate.

    Other countries have introduced incentives to increase birth rates, such as Singapore.

  • Case study: Poland and the falling birth rates

    Reasons for a declining birth rate

    More young people, especially women, want to continue their education

  • Population and precipitation distribution of China

    Towards the west of China, its sparsely populated. This is because there is less than 50mm of precipitation per year. Kashgar is an example.

    In East and South East China, its densely populated. Areas such as Shanghai have over 520 people per square mile. This is because there is low relief and high precipitation. Additionally, theres easy access to sea.

  • Case study: Ageing population in Japan


    Workforce: businesses are struggling to recruit. Many pensioners are having to continue to work. A solution is to encourage migrant labour.

    Pensions: the Prime Minister has introduced reforms which includes the retirement age being increased from 60 to 65 by 2030 and higher pension contributions from employers, employees and the government.

    Health care: Many pensioners are living in nursing homes or care homes now. This is putting pressure on the health budget, more than half goes towards caring for the elderly.

    In 2006, incentives were introduced to promote independent living at home. A health insurance scheme for over 75s were introduced in 2007. It has been nicknamed the hurry up and die scheme.

    To shorten hospital admissions, a fee a hospital receives after 100 days goes up.

    One care home has hundreds on the waiting list, not enough staff work there for everyone to be admitted.

  • Case study: Ageing population in Japan (continued)


    The greying yen: the elderly saved money. Now, Japanese pensioners are spending; buying luxury goods, travelling and indulging their taste for expensive food. This benefits their economy.

    In the past, their saved money would go to their children to help look after them at an old age.

    Now, children are doing less of the caring.

    Technology: Japan has a range of gadgets to support the ageing population. It allows young relatives to keep in touch with their elderly relatives.

    This includes an online kettle that automatically sends emails to up to three people when its switched on.

    Also, internet-linked sensors that can be attached to fridge doors and bathroom mats.
