What type of human population is represented by the following age pyramid?
Show Hint
An urn-shaped age pyramid indicates a decrease in the number of individuals in younger age groups and a smaller proportion of individuals in older age groups.
The age pyramid is a graphic representation of the abundance of individuals of various age groups with -
Pre-reproductive individuals at the base.
Reproductive individuals in the middle.
Post-reproductive individuals at the top.
The triangular age pyramid has a high proportion of pre-reproductive individuals, fewer post-reproductive individuals, and a moderate number of reproductive individuals. It represents a rapidly growing population.
In a bell-shaped age pyramid, the number of pre-reproductive and reproductive individuals is almost equal while the post-reproductive individuals are comparatively fewer. It represents a stationary population where the growth rate is nearly zero.
In an urn-shaped age pyramid, the number of reproductive individuals is higher than the number of pre-reproductive individuals. It represents a declining or diminishing population.
Hence, option C) is the correct answer.

Approach Solution -2
Yes, option C is correct.
The age pyramid shape represents a declining population where the number of people in older age groups is greater than the number of people in younger age groups. This indicates that there are fewer births with a decrease in the population size over time.

The Correct Option is (C), the declining population is represented by an "urn-shaped" age pyramid which indicates a decrease in the number of individuals in younger age groups and a smaller proportion of individuals in older age groups.
