THE DEMOGRAPHIC TRANSITION MODEL!
(OR THE DTM)
(OR THE DTM)
A demographic transition model is a graph that shows population change over time!
To the left, you can see an example of a simple DTM. As you can see, there are five stages to the DTM:
STAGE 1, which is known as the High Stationary
STAGE 2, which is known as the Early Expanding
STAGE 3, which is known as the Late Expanding
STAGE 4, which is known as the Low Stationary
STAGE 5, which is believed to be 'Declining'.

This is an example of a more complex DTM. Underneath, it explains why country go from stage to stage, and examples of countries that are currently in certain stages.
NOTE:
The time that a stage lasts for varies! For example, the world as a whole stayed in high stationary for thousands of years, but went from early expanding to late expanding in a few hundred.
