Age-Sex and Population Pyramids

The most important demographic characteristic of a population is its age-sex structure—the distribution of people's age and sex in a specific region. Age-sex pyramids also known as population pyramids graphically display this information to improve understanding and make comparison easy. An age-sex pyramid breaks down a country's or location's population into male and female genders and age ranges. Usually, you'll find the left side of the pyramid graphing the male population and the right side of the pyramid displaying the female population. Along the horizontal axis x-axis of a population pyramid, the graph displays the population number. Or, the number can stand for a percentage of the population at that age—how many percent of the entire population are of a certain age. The center of the pyramid starts at zero population and extends out to the left for males and right for females in increasing size or proportion of the population.

Population pyramid , graphical representation of the age and sex composition of a specific population. The age and sex structure of the population determines the ultimate shape of a population pyramid , such that the representation may take the form of a pyramid, have a columnar shape with vertical sides rather than sloped sides , or have an irregular profile. In a population pyramid, the size of the population under investigation is depicted on the horizontal axis, and age is aligned on the vertical axis. The result is a series of bars stacked on top of one another, each representing an age category typically in 5-year age groups , with the youngest age group represented by the bottom bar and the oldest age group by the uppermost bar.
