Explanation
A population pyramid, also known as an age-sex pyramid, is a graphical representation used to visualize the demographic structure of a population [1]. It displays two primary variables: age groups and sex indicators [4]. Conventionally, the vertical axis (y-axis) represents various age groups, typically arranged from the youngest at the bottom to the oldest at the top [4]. The horizontal axis (x-axis) shows the population size or percentage, with the graph divided down the center to separate males and females [4]. Usually, males are depicted on the left side and females on the right [1]. This dual-variable representation allows demographers to analyze birth rates, death rates, and life expectancy while observing the balance between genders across different cohorts [3]. Therefore, both age-groups and sex indicators are essential components displayed in these pyramids.
