Please label the axes. http://en.wikipedia.org/wiki/Population_pyramid http://en.wikipedia.org/wiki/Population_pyramid It typically consists of two back-to-back bar graphs, with the population plotted on the X-axis and age on the Y-axis, one showing the number of males and one showing females in a particular population in five-year age groups (also called cohorts). Males are conventionally shown on the left and females on the right, and they may be measured by raw number or as a percentage of the total population. http://xkcd.com/833/ http://xkcd.com/833/ kb
