Question

An urn shaped population age pyramid represent

• A. threatened population
• B. declining population
• C. growing population
• D. static population

Answer 1

The correct option is B declining population

A pyramid with a narrow base is also known as the declining age pyramid. It represents low fertility, low death rate, high life expectancy and increased ageing of the population. In this particular type of population the birth rate is less than the death rate which causes the actual population growth rates to be negative. Thus the actual shape of the graph is urn shape or bulb shape. While the shape of growing population and static population are pyramid and bell shaped respectively.
