The Demographic Transition Model Lucy Avant and Ronny Serio

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

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

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

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

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

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

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

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

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
