  1. The Demographic Transition Model Links to Rostow’s Ladder of Economic Development (Modernization Model)

  2. DTM: Stage I • Low 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 deaths • The society resists technological changes due to a rigid social structure

  4. Stage I and Rostow • Stage 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 II • High-growth stage in which the area experiences high birth and declining death rates resulting in significant population increase • Marked by the beginning of the Industrial Revolution AND the 2nd Agricultural Revolution • Improved seed selection • New methods of crop rotation and technology such as seed drill • Selective breeding of livestock • The number of people needed to farm DECREASED • The food supply INCREASED • Sanitation facilities and modern medical practices improved and diffused preventing the spread of disease • Combination of improved food supply and medical practices result in reduction of death rate • Birth rates fell slower, thus population explosion

  6. Stage II continued • Most 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 2000. Features of the second stage of the demographic transition.

  7. Stage II and Rostow • Rostow’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 diversify • Once this takes place, the country experiences something like an Industrial Revolution • Urbanization, industrialization, technological advancements and mass production increases.

  8. DTM: Stage III • Moderate-growth stage : declining birth and already low death rates resulting in continuing population increase at a slower rate • Lower birth rates occurred because of: 1. Greater urbanization, wealth, and medical advancements 2. Migration to urban centers; large families unneeded 3. New job opportunities for women delay marriage and pregnancies 4. Contraceptives and accessibility to abortions reduce births • In 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 Rostow • Stage III of the DTM corresponds with Rostow’s 4th stage, Drive to Maturity • Technologies diffuse • Industrialization and international trade expands • Modernization occurs • Population grows slowly

  10. Stage IV • Low-growth or stationary stage : low birth and death rates resulting in low rate of growth • Occurs in countries where women are most educated and involved in the labor force

  11. Stage IV and Rostow • Stage IV of the DTM corresponds to Rostow’s final stage of High Mass Consumption • Countries in this stage will have high incomes and widespread production of many goods and services • Majority of workers enter the service sector of the economy
