The Demographic Transition Model
  1. Definition
    1. Suggests that all countries pass through similar DT stages or will do given time
      1. Describes a sequence of changes over a period of time, between BR's, DR's and overall population
      2. Advantages
        1. Gives us a good generalised picture of population change over time
          1. Gives us a picture for the future
            1. Easy to compare different countries and their state of development
            2. Disadvantages
              1. Based on European countries (not LEDCs)
                1. Original model didn't include stage 5
                  1. Doesn't include migration, major disasters, HIV or government polies
                    1. Doesn't give a timeline for how long each stage might take
                    2. Stages
                      1. Stage 1
                        1. High stationary or pre-transition phase
                          1. High death rates due to disease
                            1. Consequently high birth rates to increase chances of survival
                          2. Stage 2
                            1. Early expanding or early transition phase
                              1. Death rate begins to decline with better living standards
                                1. Birth rate remains high as children = labour
                                  1. Massive population growth
                                  2. Stage 3
                                    1. Late expanding or mid-transition phase
                                      1. Improved technology in agriculture and industry, better education and birth-control
                                        1. Decline in birth and death rate
                                        2. Stage 4
                                          1. Low stationary or late transition phase
                                            1. Low levels of fertility and mortality
                                              1. Minimal growth
                                              2. Stage 5
                                                1. Birth rates fall below death rates
                                                  1. Population decline
