Population structure is the composition of a given population, which is broken down into categories such as age and gender. Population structure can be used to categorize populations into many subsections and demonstrate population demographics on a local, regional or national scale.

Population structure is typically presented in a pyramid-style format. Population pyramids can be large or small, depending on the size of population they represent and the different factors that they display. Population pyramids show the breakdown of populations in towns, cities, continents or countries based on certain characteristics, such as gender, socioeconomic status and age. These pyramids organize population data and are useful for showing trends and patterns of the past, present and future.
