A population pyramid often contains continuous stacked-histogram bars, making it a horizontal bar diagram.The population size is shown on the x-axis (horizontal) while the age-groups are represented on the y-axis (vertical). The size of each bar can be displayed either as a percentage of the total population or as a raw number. Males are conventionally shown on the left and females on the right.
