What type of human population is represented by the following age pyramid?

Explanation

An age pyramid is a graphic representation of an abundance of individuals of different age groups with pre-­reproductive individuals at the base, reproductive individuals in the middle and post­-reproductive individuals at the top. A triangular age pyramid has a high proportion of pre­-reproductive individuals, a moderate number of reproductive individuals and fewer post­-reproductive individuals. It represents a young or rapidly growing population. In a bell­-shaped age pyramid, the number of pre­-reproductive and reproductive individuals is almost equal. Post-reproductive individuals are comparatively fewer. It represents a stable or 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.
