Abstract
Population pyramid or age-sex pyramid generally represents the structure of population of a region on the basis of age and sex. This graphical representation provides a great deal of information about fertility, mortality and migration or population dynamics. Generally, demographers identify three types of population pyramids – expansive or rapid growth, stationary or slow growth and constrictive or contractive or negative growth pyramids. At a fix point of time different countries show different types of population pyramids and over the period of time the shape of pyramids also changes. The objectives of the present paper are – (i) to define population pyramid; (ii) to describe the types of population pyramids; (iii) to associate different stages of demographic transition with different types of pyramids; and (iv) to highlight the significance of population pyramids.
