What is a popualtion pyramid?

Answer 1

A population pyramid is not a structure, like a pyramid in Egypt. It is a graphic presentation of the population of a country. in the horizontal is the amount of people, in the vertical their age. Since there are usually more young people than old people in a population (country), the figure tends to be wide in the bottom, and slowly becomes smaller as you go up. this indicates for every age how many people there are within a population (for example, country). The form is that of a triangle, or pyramid, with the top pointing up. If this figure is distorted, because for example many people were born in a certain period (often after wars end), then the figure will not look like a pyramid at all. this way you can easily see how the population is built up in categories of age. This is important because you will have to know how much working people there are, how many coming, and who will be taking care of you once your old.
