2.2 / 2.3 Notes

Consequences of population distribution


Economic/Political/Social

Social services and infrastructure

- the closer people ( more clustered) are together the less social services need to be provided

-cheaper 

Economics

-less clustered less competition, more clustered more competition

-Urbanization because of manufacturing and industrialization

-Uneven distribution equal uneven development

Lower wages→less access to services→overall less development 

               High ag density→low development

Political 

-representation is government 

  • Districts with roughly equal population

  • Determines representation

  • Reditricting after census every 10 years

Natural/Enviromental/Physical

-carrying capacity: maximum population environment can sustain 

  • High population density= pressures on arable land, water, resources, and food supply

  • Air and water pollution, depletion of natural resources, use of large amounts of energy, excessive waste

Population Composition


Population structure 

-Significantly impacts pollitically, socially, and economically

-populations with less children now despretly need more children like china 

-high rates of children is caused by adults having a lot of kids and high rates of old people is caused by people not having children 


Population pyramid:

Women are always right so they are on the right, men are on the left


  • Prereproductive range: 0-14

  • Reproductive range: 15-44

  • Post reproductive range: 44+


-Pyramid with large base means population is growing

-Pyramid that is filled out means population is stable

-Pyramid with large top means population is decreasing 

Why its important 

-more children (large bottom)  need more jobs

-more old people (large top) more old age homes

-track needs of citizens 



Arithmetic -- population/ ki of land


Agriculture -- farmers/ arable land


Physiological -- population/ arable land
