The age-sex distribution of a population is depicted by a population pyramid.
Sex is displayed on the left or right sides of this visual profile of residents of a population, while the y-axis displays age and the x-axis represent the percentage of the population.
In other words, the percentage of a state's population in a five-year age cohort is depicted in this diagram.
The population pyramid's shape suggests three different forms of population growth: broad base (rapidly rising population), narrow base (stable population), and very thin base (Declining population).
