Demographic Transition Model – A model showing how populations should change over time in terms of their birth rates, death rates and population size
Above we demonstrate graphically the transition of a beautiful model (demographic transition model) from birth (birth rate) to how popular (population size) she became up to her death (death rate) at only 36.
This reminds you that a demographic transition model is a graph showing the birth rate, death rate and population size over time, as below:
A demographic transition model shows how the population of a country changes as the country develops over time.
The model is divided into several stages:
Stage 1: Birth rate and death rate are high – low natural increase, low total population
Stage 2: Birth rate is high, death rate is falling – high natural increase (population growth)
Stage 3: Falling birth rate, low death rate – high natural increase (population growth)
Stage 4: Birth rate and death rate are low – low natural increase, high total population
A demographic transition model does not take into account migration.
Studying how populations change helps governments in their forward planning for services like childcare, education and care of the elderly.
