In developed countries, the population is distributed relatively evenly over all age categories. Due to high fertility rates and low survivorship, developing countries often have a skewed age structure, with a higher percentage of their overall population being in the lower age categories.
How does demographic transition relate to a country’s development?
Within the model, a country will progress over time from one stage to the next as certain social and economic forces act upon the birth and death rates. Every country can be placed within the DTM, but not every stage of the model has a country that meets its specific definition.
Are developing countries experiencing a demographic transition?
On the other hand, the transition in developing countries started only in the second half of the twentieth century. The transition was more rapid but also accompanied by higher growth rates of the population, up to three to four percent per year.

What are the factors that would affect demographic transition?
These include the progression of population growth rates; fertility and mortality rates; urbanization; pattern of migration and differences in the economic factors responsible for the timing and speed of these drivers of demographic change.
What are the four stages of demographic transition?
