POPULATION PREDICTION PROBLEMS

  • Issue 1- compounding
  • Issue 2- emigration and immigration
  • Issue 3- culture consideration
  • Issue 4- chronic disease
  • All of these issues affect the population
2.

ISSUE 1-COMPOUNDING

  • Fertility rate affects population
  • Example: China because only one baby per woman
  • Example: Uganda because eight babies per woman
  • The amount of babies born per woman continues for generations
  • This can affect the population positively or negatively: too little or too many babies
3.

ISSUE 2- EMIGRATION & IMMIGRATION

  • Emigrate- to move from a place
  • Immigrate- to move to a place
  • Most people migrate for mainly economic reasons
  • Refugees- people who must leave an area because they are in danger
  • War is a common reason for people to be pushed out of an area
4.

ISSUE 3- CULTURE CONSIDERATION

  • The spread of a culture affects population
  • Some cultures don't care about what stage an area is in, they still make many babies
  • Example: people in India have many kids even though having them in their stage is bad
  • Government can also affect population. Ex: one child law in China
  • Culture is a large influence on population
5.

ISSUE 4-CHRONIC DISEASE, NATURAL DISASTERS, WAR

  • Natural disasters and war take out CHUNKS of the population
  • Chronic disease is more apart of the modern era
  • These factors greatly affect the population growth rate
  • Ex: WWII...populations were wiped out by Hitler and his army. He killed 2/3 of a cultural group!!
  • Ex: AIDS in Uganda had killed many and put many in jeopardy
6.

"HOW MANY AND WHERE?" CONNECTION

  • Culture is a huge influence on population in a certain area
  • Ex: In Uganda, their culture is to have many babies, therefore they do!!
  • The amount of people in an area can be too little or too many
  • If too little, then there won't be enough people working, thus causing decrease in economic success
  • If too many, then there could be overpopulation, which leads to famines and other issues
