Q. Which of the followng statement is true for an urn-shaped pyramid?
Solution:
An age pyramid is a structural representation of age distribution (percent individuals of a given age or age group) plotted for the population.
Age pyramid given here is the 'urn-shaped' age pyramid. It has a few pre-reproductive individuals followed by many reproductive individuals. As there are fewer individuals in the pre-reproductive group, the population size will decline with time. Such a population shows a declined growth (negative growth).
