The demographic transition strengthens economic growth process through three changes: a reduced dilution of capital and land stock, an increased investment in human capital, and an increased size of the labour force relative to the total population and changed age population distribution. [2]
The Zelinsky Model of Migration Transition, [1] also known as the Migration Transition Model or Zelinsky's Migration Transition Model, claims that the type of migration that occurs within a country depends on its development level and its society type. It connects migration to the stages within the Demographic Transition Model (DTM).
Population momentum is a consequence of the demographic transition. Population momentum explains why a population will continue to grow even if the fertility rate declines or continues to decline even if the fertility rate grows. Population momentum occurs because it is not only the number of children per woman that determine population growth ...
The theory states that these first settlers have significant impact on the social and cultural geography of the area, however few these first settlers may have been. They lay the groundwork for the following generations and are perhaps more important than the contributions of thousands of new immigrants generations later. [ 7 ]

Human population projections are attempts to extrapolate how human populations will change in the future. [99] These projections are an important input to forecasts of the population's impact on this planet and humanity's future well-being. [100] Models of population growth take trends in human development and apply projections into the future ...
In demography and population dynamics, the rate of natural increase (RNI), also known as natural population change, is defined as the birth rate minus the death rate of a particular population, over a particular time period. [1]
In the demographic transition model, the size and shape of population pyramids vary. In stage one of the demographic transition model, the pyramids have the most defined shape. They have the ideal big base and a skinny top. In stage two, the pyramid looks similar but starts to widen in the middle age groups.
