Demographic transition model stages

Question 1

Stage 1

Answer 1

High CBR
High CDR
Low NIR

Question 2

Stage 2

Answer 2

High CBR
Low CDR
NIR rises because CDR declines

Question 3

Stage 3

Answer 3

CBR Declining
CDR low
NIR moderates bc the CBR starts to decline

Question 4

Stage 4

Answer 4

Low CBR
Low CDR
Low NIR

Question 5

Stage 5

Answer 5

Lower CBR
Increasing CDR (more elderly people than young)
0 to negative NIR
Characterized as a decline in population bc CDR exceeds CBR
-Over Ike fewer women in child bearing years (more CBR falls)

Question 6

Stage 1 migration

Answer 6

High daily or seasonal mobility in search of food

-little migration

Question 7

Stage 2 migration

Answer 7

High international emigration and inter regional migrants on from rural to urban areas
-International migration

Question 8

Stage 3 migration

Answer 8

High international immigration and intraregional migration from cities to suburbs
-Internal migration

Question 9

Stage 4 migration

Answer 9

High international immigration and intraregiinak migration from cities to suburbs
-internal migration

Question 10

Epidemiologic transition stage 1

Answer 10

Pestilence and Famine (High CDR)

• Infectious and parasitic diseases main cause of death
• Black plague
• Shift to agriculture mean more contact with infected animals and human waste

Question 11

Epidemiologic transition

Answer 11

Focuses on distinct health threats in each stage of the demographic transition

Question 12

Epidemiologic transition stage 2

Answer 12

Receding Pandemic (rapidly declining CDR)

• Factors that reduced the spread of disease during industrial revolution (improved: sanitation, nutrition, medicine)
• Cholera pandemic in London
• Typically happens in wealthy or developed nations
• Developing nations still suffer from infectious diseases more than chronic diseases

Question 13

Epidemiologic transition stage 3

Answer 13

Degenerative diseases (Moderately declining CDR)

• Decrease in deaths from infectious diseases
• Increase in chronic disorders associated with agent
• Cardiovascular disease
• Cancer
• Human created disease (pollution)

Question 14

Epidemiologic transition stage 4

Answer 14

Delayed Degenerative diseases (Low but Increasing CDR)

• Deaths caused by cardiovascular disease and cancer delayed because of modern medical treatments
• Life expectancy of older people is higher through medical advances

Question 15

Transistor to stage two cause

Answer 15

Aka Epidemiologic transition

• Agricultural technology (more food)
• Medical technology (better treatments)
• Public sanitation technology (safer and cleaner living conditions)

Question 16

Transition to Stage three in classic DTM

Answer 16

AKA fertility transition

• Societies become less rural and more urban (decline in childhood death, change traditional values about having children, city living raises cost of dependents)
• Women more influential in child bearing decisions (women enter work force and increasing female literacy)
• Improved contraceptive technology, availability of birth control

Question 17

Epidemiologic transition stage 5

Answer 17

Evolution
Poverty (Unsanitary and people too poor to buy medication)
Increased connections (people can travel easily and quickly and so can diseases)
