The shape of the pyramids reflects the growth status of the population. Identify the type of age pyramid represented below for human population.
- Ascending
- Expanding
- Stable
- Declining
The Correct Option is D
Approach Solution - 1
The pyramid shown represents a (D) Declining population.
Expanding: Expanding populations have a wide base (lots of births) and progressively narrower tiers. This represents a high birth rate and lower life expectancy.
Stable: Stable populations have relatively even tiers, with only a slight tapering towards the top. Birth and death rates are relatively balanced. This is what the image depicts.
Declining: Declining populations have a narrow base (few births) and wider tiers in the older age groups. This represents a low birth rate and a higher life expectancy.
Approach Solution -2
A population pyramid is a graphical representation of the age and sex distribution of a population. It typically shows the proportion of males and females in various age groups. Population pyramids are used by demographers and policymakers to understand the demographic structure of a population and to assess social and economic trends.
The pyramid shown represents a (D) Declining population.
