Test. The graph below summarizes the demographic transition model across the model’s five stages, showing the trajectory of death and birth rates as well as total population: The demographic transition model is a highly useful model for making educated guesses about how populations are likely to shift in the future. DTM is likely to continue to evolve as the real world evolves. The "Demographic Transition" is a model that describes population change over time. In developed countries, this transition began in the eighteenth century and continues today. The Demographic Transition Model (DMT) shows how birth and death rates change as country goes through different stages of development. You might guess that their continuing economic development would mean the country’s population would follow the patterns of the DTM.

The con… Demographic transition refers to the shift in vital rates within population groups at various geographical scales from a pattern of high birth (fertility) and death (mortality) rates to one of low rates. The demographic transition theory represents the changes from high death and birth rates to significantly low rates over a given period. As described above, when first to the second stage.
