Document Summary
It is a picture of a population. Sometimes it looks like a pyramid, but not always. It is a graph that has age groups in the vertical axis. Starting with the youngest age groups at the bottom and then going up. On the bottom there is the age distribution of the population. You will most commonly see them with a percent at the bottom. It is almost always done with women on the right and men on the left. This means in india in 2000 there were about 60 million 0-4 year old boys and 57 million 0-4 year old girls. You can group the bars on the population period in different ways. This helps us think about whether the population is old or young. Middle group is thought of as the working population. These population pyramids tell us a lot about populations because of age and sex structures in population and how it relates to demographic processes.
