A Population pyramid consists of horizontal bars emerging from a centerline in both directions of the X-axis. The bars emerging to the left indicate the population of males, while bars emerging from the right indicate females. The bars are arranged in such a way, that the top bar shows the newborn population and the age bracket increases as we go down, this visualization looks like a pyramid.
Why do you need it?
We need this chart to visualize a region’s or a country’s distribution of various age groups. By this distribution pattern, we can analyze the trend of population and if any irregularity arises, then it could be improved by certain measures.
What kind of data you can visualize with it?
This chart is best suited for population-related data. If you have a dataset in which you have a population per age bracket of a country or region, then undoubtedly you can use the population pyramid.
