A population pyramid is a graphical representation of the distribution of a population by age and sex. The pyramid typically displays age groups vertically and separates males and females horizontally. Thus, both age groups and sex indicators are displayed.
A population pyramid visually depicts the age-sex structure of a population.
The shape of a population pyramid provides insights into the demographic history and future potential of a population, including birth rates, death rates, life expectancy, and migration patterns. A broad base indicates a high birth rate, while a narrow base suggests a low birth rate. A large proportion of older people suggests higher life expectancy.
