Age Structure Diagrams

Get free examples of age structure diagrams in these printable diagram resources! An age structure diagram (population pyramid) is a graphical illustration that shows the distribution of various age groups in a population (typically that of a country or region of the world), which forms the shape of a pyramid when the population is growing. These diagrams are often viewed as the most effective way to graphically depict the age and sex distribution of a population, partly because of the very clear image these pyramids represent. This diagram shows the distribution by ages of females and males within a certain population in graphic form. Take a look at the following age structure diagram of China below.

The age structure diagram above shows a diagram in which the ages and sexes for the China population are arranged so that ages are grouped together such as 0 – 4 years, 5 – 9 years, and so on. The population of each is group is represented as a bar extending from a central vertical line, with the length of each bar dependent upon the population total for that particular group. The centerline separates the females from the males. The female and male populations for each group are represented by the distance from the centerline, with females on the right and males on the left. Other examples of the structure diagrams are posted below.

Both age structure and age pyramids can take a variety of forms, depending on the birth and death trends within the population, as well as a host of other social factors. They can be stable, meaning that patterns of birth and death are unchanging over time; stationary, which signals both low birth and death rates (they slope gently inward and have a rounded top); expansive, which slope dramatically inward and upward from the base, indicate that a population has both high birth and death rates; or constrictive, which signal low birth and death rates, and expand outward from the base before sloping inward to achieve a rounded peak at the top.
