A paired chart, often used in data analysis, displays two related sets of data side by side. It allows for easy comparison and identification of patterns or correlations between the two datasets through various visual representations like scatter plots, bar charts, or line graphs.

The most common application is for creating "population pyramids". In a population pyramid, one gender is represented on each side of the chart, with age groups arranged vertically. This allows you to observe the overall distribution of age groups and compare the distributions between males and females.
