The model has four stages: pre-industrial, urbanizing/industrializing, mature industrial, and post-industrial.
In the pre-industrial stage, crude birth rates and crude death rates remain close to each other keeping the population relatively level..
The demographic transition can be summarized in four stages: high birth and death rates leading to slow growth, falling death rates leading to faster growth, falling birth rates slowing growth, and both rates reaching a low level, slowing growth to zero..

Voiceover: Demographic transition is a model that changes in a country's population.
It states that the population will eventually stop growing when the country transitions from high birth rates and high death rates to low birth rates and death rates, stabilizing the population..
Demographic transition is a long-term trend of declining birth and death rates, resulting in substantive change in the age distribution of a population..
What is the demographic transition? Stripped to its essentials it is the theory that societies progress from a pre-modern regime of high fertility and high mortality to a post-modern regime of low fertility and low mortality..
The demographic transition has swept the world since the end of the nineteenth century
The unprecedented increase in population growth during the Post-Malthusian Regime has been ultimately reversed, bringing about significant reductions in fertility rates and population growth in various regions of the world
A possible Stage 5 would include countries in which fertility rates have fallen significantly below replacement level (2 children) and the elderly population is greater than the youthful population
Like any model, there will be outliers and exceptions to the rule and the Demographic Transition Model is no different
The classical demographic transition theory suggests that as a country develops through the process of modernization and industrialization, its demographic transition roughly follows three stages, the pre-transition stage, the transition stage, and the post-transition stage (Rowland 2003; Weeks 2016 )
