Population (Geography) By: Dimaz Julian Pratama Grade: XI Social
Population…• Population is the all of the people who have stayed more than six months in an area when census is conducted.• Population also can be defined as all the inhabitants of a particular place.
Dynamic Demography• Demography is the statistical and mathematical study of magnitude, composition, distribution, and the changes that occur from time to time.
Population Composition• Population composition is the population grouping based on particular characteristics.• The Functions of Population Composition:• To describe population condition in an area• To describe human resources by age and gender• To provide input for demographic policy formulation• To set up national planning based on the population needed.
Population Distribution and Density• Supply of Water• Fertile Soils• Raw Materials
Population Growth In Indonesia• Natural Population Growth = The growth is resulted from the birth rate subtracted from mortality rate. T(N) = B – D• Total Population Growth = Resulted by adding natural population growth and immigration rate and subtracted from emigration rate. T(N) = (B – D) + (I – E)
Pro and Anti Natal factors to fertilityPro:• Young age marriage• Depressed for not having children• The philosophy of children to bring fortune• The philosophy of children to help parents to earn more moneyAnti:• Marriage Postpone• Limitation of incentives for civil servant• Too much children trauma• Increasing number of carrier women
• Crude Birth Rate = The ration of total live birth to population in a specified community or area over a specified period of time (6 months period) CBR = (N x P) x k• Age Specific Fertility = the annual number of births to women in a particular age group per 1000 women in that age group. ASFR = (Nx : Px) x K• General Fertility Rate = the number of live births per 1,000 women of reproductive age in a population per year. GFR = (N : P) x K
Mortality Rate• Mortality Rate is the ration of the number of the death person in area/country.• Mortality rate is divide into two types:• Pro Mortality:• Lack of health of disability, insecure healthy environment• Insufficient nutrients• Anti Mortality:• Peaceful country• Religious philosophy• Kill others• Community important of wealthy lifestyle (Higher education)
Mortality Rate Formula• CDR = D/P x K• CBR = BN/P x K• ASFR = N/P x K• ASDR = D/P x K• IMR = Do/B x k
Migration• Migration is people movement form one place to another place either temporary or permanent, individual, or group.
Immigration and Emigration• Immigration = more or less tightly controlled by host countries, who may be concerned about the effects of a large population influx or wish to achieve some kind of mix of incoming residents, or alternatively, provide a haven for a people or group suffering some kind of intense need.• Emigration = prompted by a variety of factors, as people leave their country in order to flee a war, find education or job opportunities, or join their family in another land.
Factors of Migration• There are two factors which is Push factors and pull factors of migration.Push Factors:Conditions that drive people to leave their homesExamples:• Land scarce in home country• Political and/or religious persecution• Revolutions• PovertyPull Factors:Conditions that attract people to a new areaExamples:• Promise of freedom (religious and political)• Hope for a new life• Industry• Jobs• Land
