Question

Discuss the progressive and regressive age structures.

Answer 1

In the age-sex pyramid, we can easily interpret the structure of a particular population.

The shape A in the structure shows the progressive type, which comprises of high numbers of the young population.

It shows the broad base because the population is growing in number with each day.

The shape C defines the regressive structure which is the result of a permanent reduction in a number of births, leading to population diminishing.
