Constructing and Interpreting an Age Structure Diagram If the diagram shows a generally straight up and down shape except for the older age groups, a stable population is thus revealed. If the diagram shows a top-heavy shape, then a decline is forecast for that population.

A population pyramid is a graph that shows the distribution of ages across a population divided down the center between male and female members of the population. The graphic starts from youngest at the bottom to oldest at the top.

The age structure is closely related to the birth rate, death rate and migration of a population. In the region with high birth rate, the proportion of children tends to be higher, whereas in the region with low birth and death rate, the percentage of elderly population tends to be higher.

One of the tools that demographers use to understand populations is the age structure diagram. This diagram shows the distribution by ages of females and males within a certain population in graphic form.

One of the tools that demographers use to understand population is the age structure diagram (it 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.

The percentages of the population will be plotted along the X-axis with females to the right of the center line and males to the left of the center line. The age groups will be running up the Y-axis with the youngest at the bottom and the oldest at the top.

Definition English: The age structure of a population is the distribution of people among various ages. In graphic form, age structure is portrayed as an age pyramid whose relatively broad base indicates the number of children while the peak reflects the increasing likelihood of death as people age.

Interpreting a Population Pyramid A wide base suggests high birth rate. Narrow base shows low birth rate as small numbers of children are born.A broad top or wide apex indicates high proportion of people living longer. Straight or near vertical sides depicts a low death rate.

The age structure of a population refers to the proportionate numbers of people in different age categories in a given population for a defined time. It is a natural characteristic of a population in a country or a region. The age structure is closely related to the birth rate, death rate and migration of a population.
