This statement is false.
A population pyramid is an age structure graph. It is used by demographers to study the evaluation of a given population in a specific time period.
There are three types of population pyramids:
1. Stationary pyramid: when the population contains equal birth rates and death rates.
2. Expansive pyramid: very wide at the young ages, characteristic of countries with high birth rate and low life expectancy.
3. Constrictive pyramid: narrowed at the bottom, an older population with long life expectancy and low death rate.
