Another name for population pyramid is Age-Sex graphs.
When a population pyramid has a wide base and is narrower at the top, it indicates a high birth rate and high population growth. This kind of pyramid is typical of developing countries where a large proportion of the population is young and the birth rates are high.
A bell-shaped population pyramid typically indicates a stable population with balanced birth and death rates across ages. This shape is characteristic of a developed country with low birth and death rates, resulting in a more even distribution of population across age groups.
A population pyramid would be the most appropriate graph to show the percentage of males and females by age group in a country's population. The pyramid's vertical axis represents age groups, with the broader base typically representing the younger population and narrowing towards the top, showing older age groups. The left and right sides of the pyramid represent males and females, respectively.
The population pyramid shows a decrease in the number of males as age increases, resulting in a tapered shape with fewer older males compared to younger males. This pattern reflects natural population dynamics where mortality rates are typically higher among older age groups.
The world's largest pyramid by volume is the Great Pyramid of Cholula in Mexico. It is also known as Tlachihualtepetl and is located in the state of Puebla.
