Population pyramids are graphical representations that show the age and sex distribution of a population. They are typically divided down the center, with males on one side and females on the other, and the ages are listed from youngest at the bottom to oldest at the top. Here's a breakdown of what they represent: Expansive Pyramids: These have a broad base, indicating a large number of young people, high fertility rates, and high mortality rates among younger members. The shape resembles a triangle, suggesting a growing population. Constrictive Pyramids: These have a narrower base and are wider in the middle. This indicates lower numbers of young people, lower fertility rates, and a higher proportion of middle-aged and elderly individuals. The population is likely shrinking. Stationary Pyramids: These have an even distribution across age groups, resembling a rectangle. This suggests low fertility and low mortality rates, indicating a stable population size.
