According to the textbook Biology by Campbell and Reece, published in 2002, age structure is defined as the relative number of individuals of each age in a population.
The three types of age structures are: young-age structure (high proportion of young individuals), stationary age structure (relatively equal proportion of individuals across age groups), and old-age structure (high proportion of older individuals).
Age-structure diagrams show the population of a country broken down by gender and age group.

Age structure diagramA population pyramid, also called an age pyramid or age picture diagram, is a graphical illustration that shows the distribution of various age groups.
The age structure in the United States predicts a slow but steady growth rate for the near future. The age structure in Rwanda predicts a population that will double in about 30 years.
The age structure of a population can significantly impact its economic development and social dynamics. For instance, countries with a younger age structure may experience rapid growth, while those with an aging population face challenges related to healthcare and pensions. Understanding age structure is crucial for policymakers in planning for future societal needs.

Population age structure provides insights into a population's demographics, such as the distribution of individuals across different age groups. It helps policymakers plan for future healthcare, education, and social security needs. Additionally, understanding age structure can also provide valuable information for businesses targeting specific age groups for marketing purposes.
