ASSALAMUALAIKUM WR. WB.Now we want topresentation

about PopulationDensity


3/20

Do you knowpopulationdensity ?What is it?


4/20

Populationdensity is thenumber ofpopulation perunit area

It is frequently applied toliving organism, andparticularly to humans. Itis a key geographic term


5/20

FIRSTLYWe will discuss about Citizen People who are legally entitled tolive in the area. In other wordspeople who have a formal letter to

live there.

People who live in the area

Demography is science of population problem


6/20

Cause of PopulationDensity High growth rate, A narrow area Reasons for marriage and employment. Absence of family planning Population is not comparable with area Birth rates are not comparablewith the mortality rate. Urbanization mortality, birthrate (natality),Immigration, emigration Increasingly difficult to obtain from localagricultural products A lots of natural disasters many people who believe in the saying too manychildren much good fortune

EXAMPLE OFPOPULATIONDENSITY

In year Cadbury district the area of which is 3km was occupied by 100.000 persons, then theoccupant density in that district in year 2007was 100.000 persons / km = 33.33 persons perkm, which means every area of 1 km is inaverage occupied by 33 persons

Result of PopulationDensity Income per capita decreases and thereforepurchasing power decreases decreasing public saving capabilities thatfunds for the development of reduced state Reduced employment and increasedunemployment The need for more clean air, increase crime Increase the country's economic burden,especially if the quality is low The loss of productive land, such as rice fieldsand plantations because the land is used for

settlements.


16/20

Result of PopulationDensity The reduction in the availability of cleanwater. People need clean water for life.Population will lead to increased need for cleanwater. This causes the decreased supply of

clean water. Population growth also led to increased mobilityflows. As a result, the need for increasedtransportation equipment and energyrequirements such as oil increased as well. Thisc an cause air pollution and create more oil suppliesrunning low.

population growth also led to increased householdwaste, such as waste and others. This can causeenvironmental ollution

Other methods of measurementWhile arithmetic density is the most common way of measuring

population density, several other methods have been developed whichaim to provide a more accurate measure of population density over aspecific area.Arithmetic density: The total number of people / area of land(measured in km or sq miles).Physiological density: The total population / area of arable land.Agricultural density: The total rural population / area ofagricultural land.Residential density : The number of people living in an urban area/ area of residential land.Urban density : The number of people inhabiting an urban area /total area of urban land.Ecological optimum: The density of population which can besupported by the natural resources.

Ranking in the worldbased on population1.Republik of China (1,306,313,812 inhabitants)2.India (1,103,600,000 inhabitants)3.Amerika States (298,186,698 inhabitants)4.Indonesia (241,973,879 inhabitants)5.Brasil (186,112,794 inhabitants)6.Pakistan (162,419,946 inhabitants)7.Bangladesh (144,319,628 inhabitants)

8.Rusia (143,420,309 inhabitants)9.Nigeria (128,771,988 inhabitants)10.Jepang (127,417,244 inhabitants)


19/20

Prevent ofPopulation Density Promote the program or family planning tolimit the number of children Delaying the marriage in order to reduce thenumber of high birth rate Addition and job creationWith the increasing standard of living of thepeople it is expected that loss of confidence inmany children much good fortune Increasing awareness and education on population Reducing the density of the transmigrationprogram Increasing production and sourcing of food

We think thatsenough. We apologize,if there are any unwiseword. Thanks for yourattention. Wabilahitaufik walhidayah
