Population Pyramids + DTM Flashcards
Describe Stage 1 of the DTM (high expanding) and an area which is witnessing that stage.
High birth rate, High death rate, low total population. No population growth.
Example area: Matis Tribe, Amazonia
Describe Stage 2 of the DTM (Early expanding) and an area which is witnessing that stage.
High birth rate, falling death rate, higher population. Natural increase is taking over.
Example area: Afghanistan
Describe Stage 3 of the DTM (late expanding) and an area which is witnessing that stage.
Birth rate falling, death rate coming to a optimum low. Natural increase still happening.
Example area: Brazil
Describe Stage 4 of the DTM (low stationary) and an area which is witnessing that stage.
Low birth rate, low death rate, total population high. Population is staying at an even level where the replacement rate is at a good standard.
Example area: UK
Describe Stage 5 of the DTM (declining) and an area which is witnessing that stage.
Death rate is starting to beat birth rate, birth rate low, death rate slightly higher, total population falling. Natural decrease taking place.
Example area: France
Top of the population pyramid is called the:
Apex
Bottom of the population pyramid is called the:
Base
A wide middle section of the triangle indicates
A high amount of economically active
A sharp pyramid suggests:
High death rate and short life expectancy
What does a pyramid look like for High fluctuating (stage 1)?
Short apex, wide base, curved arrow head shape
What does a pyramid look like for early expanding (stage 2)?
Taller apex, wide base, straight triangle
What does a pyramid look like for late expanding (stage 3)?
Tall apex, smaller base, more of a dome shape
What does a pyramid look like for low stationary (stage 4)?
Perfect sized base, tall apex, oblong shape
What does a pyramid look like for declining (stage 5)?
Small base, large apex, wide amount of people aged between 18 and 64, starting to look like it is retracting underneath triangle.
A wide base means:
High birth rate
