1. The Demographic Transition Model
Lucy Avant and Ronny Serio

2. What Does This Display?
The demographic transition model shows the process of population development over time
There are 4 stages and a possible 5th

3. Stage 1 High CBR and high CDR; very inconsistent
Population remains steady at minimal to no growth
During this stage wars, disease, and droughts are very common keeping growth to little or none
Subsistence farming is the main source of agriculture
Hunting and gathering
Slight crop manipulation
Currently there are NO countries in stage one

4. Stage 2 CDR plummets and CBR remains the same
CDR plummets due to medical advancements
Very high population growth
During this stage the country is experiencing urbanization and mechanizing
With this mechanization agriculture becomes more efficient
Currently many LDC’s remain in this stage
In Africa, Central America, and Southern Asia

5. Cape Verde 12 islands off the coast of West Africa CDR- 7 CBR- 25
Large number of females that will soon be in their child bearing years
To enter stage 3 these women must conceive less children than their parents
Through women’s sufferage
Birth control access

6. Stage 3 CBR begins to drop as CDR remains the same
The gap between the two lessens
Even more advanced medical care and changing gender roles
During this stage the country is experiencing later marriage, women's suffrage, and low access to contraceptives
Currently some MDC’s are in this stage

7. Chile An elongated country on the west coast of South America CDR- 8
CBR- 20
Chile has not made further advances 80 years to reduce the gap between CDR and CBR
Reduced income and high unemployment made couples postpone conception
Unlikely to move into stage 4 due to government policy

8. Stage 4 CBR declines and CDR remains constant
CDR and CBR begin to equal each other
Zero percent growth
During this stage countries are experiencing an ageing population, accessible birth control, later marriage, and jobs for women
Currently most MDC’s are in this stage
Western Europe and North America

9. Denmark Denmark is a small country in Northwestern Europe CDR-12
CBR-12
This means that they have roughly zero percent growth
The number of elderly people exceeds that of the young
This means there is not a large enough work force to support the elderly
With further medical advances elderly may live longer making the issue worse
CDR has increased due to elderly population and is unlikely to decline

10. Stage 5 CBR dips under CDR Population decline
Causing negative population growth
During this stage countries are experiencing a large elderly population
Also low unemployment due to the lack of youth to fill jobs
Currently this is a theoretical stage, as NO countries are in this stage
