Age structure diagram is one of the tools that demographers use to understand population. This diagram is sometimes called a population pyramid, but it is not always pyramidal in shape. This diagram shows the distribution by ages of females and males within a certain population in graphic form. Check out the first example posted in the image below.
The age structure of a population is the distribution of people among various ages. These age structure diagrams are important to understand because they have a host of social and economic implications in society, like understanding the resources that must be allocated for childcare, schooling, and healthcare, and the familial and greater social implications of whether there are more children or elderly in society. In graphic form, age structure is portrayed as an age pyramid that shows the youngest age cohort at the bottom, with each additional layer showing the next oldest cohort. Typically males are indicated on the left and females on the right, like the diagrams below.
Population pyramids often contain continuous stacked-histogram bars, making it a horizontal bar diagram. The population size is depicted on the x-axis (horizontal) while the age-groups are represented on the y-axis (vertical). The size of the population can either be measured as a percentage of the total population or by raw number. The U.S. age pyramid also shows how birth rates have shifted over the years.
