26
Q

Crude Death Rate

A

the number od deaths in pouplation

27
Q

causes and effects of CDR

A

A high CDR is a result from a high number of natural deaths among old people when that segment is a large % of the Population
A high CDR can result from unclean water, inadequate health care, and poor housing
The CDR can spike due to natural disasters or increase for longer periods due to disease or war.

28
Q

Demographic Transtion model

A

represents the shifts in growth that he world’s populations have undergone over time
Each stage of The DTM is characterized by the relationship between birth rates and death rates
Geographers use the DTM to better understand the relative stability of population and the factors that have contributed to population growth.
According to the model, all regions, countries, and societies go through the first 4 stages and they rarely return to an earlier stage.

29
Q

DTM stage one

A
  • there is never a stage one coutnry
  • pre - industrial age, early times, Dark Ages
    -Less food no health
    -agrarian society ( agricultural society)
    -High birth rate, no birth control
    -High death rate because of low standard of living and no medical care
30
Q

Stage 2 DTM

A

Industrial Revolution/new inventions
Warming period : more food = more people = not everybody needed to farm = Industrial Revolution = Agricultural revolution = Urban revolutio : THESE LED TO STAGE 3
Farming and Medicine starting to emerge
Death rates begin to fall because of higher food supply and medical advancements
Birth rates are still high
Life expect each begins to increase due to agricultural production
CBR = High
CDR= Rapidly decreasing
Population increase
Secondary economic sector

31
Q

stage 3 DTM

A

India, Mexico, China
mature industrial economy
both rates droptor
fertility begins to fall as more children live to begin adults
Higher standards of living makes having kids expensive
small families
population growth slows
more people living in cities/ less babies
tertiary sector
CBR = decreasing
CDR = Decreasing

32
Q

stage 4 DTM

A

U.S, Canada
post industrial economy more recent
birth and death rates and very low
population grows slowly or can even begin decrease
Birth and Death rates are stable
CBR, CDR, Population : Stable
ZPG : zero Pouplation growth

33
Q

stage 5 DTM

A

taly, Germany, Japan in stage 5
Countries that are deindustrializing
Going from manufacturing to service and information based on industries
Countries facing negative birth rates, people not replacing themselves
Death rate stays the same
CDR = stable
CBR = has potential to fall below the death rate
Population has potential to drop

34
Q

DTM overall overveiw of countires

A

stage 1 and 2 - developing periphery
stage 3 - Newly Industrail countries, Semi periphery
stage 4 and 5 - More developloed countries, core counties

35
Q

Epidemilogic trasition model

A

Describes changes in fertility, mortality, life expectancy, and population age distribution - largely as the result of changes causes death.

explains causes of changing death rates

36
Q

ETM stage 1

A

famine

death rate high life expectecy low

37
Q

ETM stage 2

A

Receding pandemic Disease

medice lowers spread of infection
death rate decreases and life expectancy increases

38
Q

ETM stage 3

A

degenerative and huma created diseass

diseases due to aging
death rate low life expectancy increases

39
Q

ETM stage 4

A

delayed degetnrattive diseases

medice slows down death rate

life expectancy at its highest

40
Q

REemergence of infectious dieases

A

increased proverty. Increased interconnectedness - connected through trains, plans, and evolving bacterias/virus

life expectacy decreases

41
Q

Limitations of ETM

A

focuses only on health-related factors, usually diseases

Overlooks the role of poverty, when determining disease risk and mortality
It is unknown how human caused environmental factors might affect the causes of mortality as described in the ETM.

42
Q

Nonvectored disease

A

spread directly from person to person

43
Q

Vectored disease

A

spread through insect,

44

53
Q

A
  • a rapidly growing pouplation may exceed the land’s carrying capacity
  • land degradation: long term damage to the soil’s ability to support life may result from overuse of resources .
53
