Presentation on theme: "The Demographic Transition Model"— Presentation transcript:
1 The Demographic Transition Model Links to Rostow’s Ladder of Economic Development (Modernization Model)
2 DTM: Stage ILow Growth stage in which the area experiences incredibly high birth and death rates resulting in little population growth.Death was the result of plagues and epidemics.Europe: Bubonic Plague (Black Death)
3 Stage I Continued…Stage I: Subsistence agricultural society which produces little food.Famine contributes to the deathsThe society resists technological changes due to a rigid social structure
4 Stage I and RostowStage I correlates to the first stage of Rostow’s Modernization Model - traditional.In Stage I of the DTM the people are traditional,subsistence agricultural societies.These societies resist modernization and technology.
5 DTM: Stage IIHigh-growth stage in which the area experiences high birth and declining death rates resulting in significant population increaseMarked by the beginning of the Industrial Revolution AND the 2nd Agricultural RevolutionImproved seed selectionNew methods of crop rotation and technology such as seed drillSelective breeding of livestockThe number of people needed to farm DECREASEDThe food supply INCREASEDSanitation facilities and modern medical practices improved and diffused preventing the spread of diseaseCombination of improved food supply and medical practices result in reduction of death rateBirth rates fell slower, thus population explosion
6 Stage II continuedMost of the world population is trapped in Stage II of the demographic transition.Limited resources and cultural practices maintain unnecessarily high birth rates.The segments of the world population that hold the fewest resources have the most rapidly growing populations.India in the year Features of the second stage of the demographic transition.
7 Stage II and RostowRostow’s stage II (preconditions of takeoff) and stage III (takeoff) correlate to stage II of the DTM.Governments and its people allow the country to diversifyOnce this takes place, the country experiences something like an Industrial RevolutionUrbanization, industrialization, technological advancements and mass production increases.
8 DTM: Stage IIIModerate-growth stage : declining birth and already low death rates resulting in continuing population increase at a slower rateLower birth rates occurred because of:1. Greater urbanization, wealth, and medical advancements2. Migration to urban centers; large families unneeded3. New job opportunities for women delay marriage and pregnancies4. Contraceptives and accessibility to abortions reduce birthsIn the figure notice there are also fewer births. This is stage three of the demographic transition model. Chile would be a good example.
9 Stage III and RostowStage III of the DTM corresponds with Rostow’s 4th stage, Drive to MaturityTechnologies diffuseIndustrialization and international trade expandsModernization occursPopulation grows slowly
10 Stage IVLow-growth or stationary stage : low birth and death rates resulting in low rate of growthOccurs in countries where women are most educated and involved in the labor force
11 Stage IV and RostowStage IV of the DTM corresponds to Rostow’s final stage of High Mass ConsumptionCountries in this stage will have high incomes and widespread production of many goods and servicesMajority of workers enter the service sector of the economy
