AGE STRUCTURE Meaning and
Definition
-
Age structure refers to the composition of a population in terms of age groups or cohorts, providing a snapshot of the distribution of various age categories within a particular population at a given time. It is a crucial demographic indicator used to understand the changing dynamics of a population, which in turn, helps to analyze and forecast social, economic, and political trends.
Age structure is typically represented graphically through population pyramids, illustrating the proportion or percentage of individuals within different age groups, often categorized into five-year intervals. These pyramids consist of vertical bars, with the width of each bar representing the proportion of individuals in a specific age group, while the horizontal axis reflects the age groups or cohorts being evaluated. The shape of the pyramid displays the age distribution within the population.
An age structure diagram can reveal valuable insights into a population's characteristics, such as the proportion of children, working-age individuals, and older adults. This information aids in understanding various social issues like healthcare, education, labor force dynamics, and dependency ratios. Analyzing age structure can also assist policymakers in planning for future needs related to pensions, healthcare services, and infrastructure development.
The age structure of a population is influenced by several factors, including fertility rates, mortality rates, and migration patterns. As these factors change over time, so does the age structure, leading to shifts in population distribution and potential impacts on social and economic systems.
In summary, age structure pertains to the representation and distribution of different age cohorts within a specific population, aiding in the analysis of demographic trends and informing policies and strategies related to various aspects of society.

Etymology of AGE STRUCTURE
The word "age structure" doesn't have a specific etymology of its own. Rather, it is a combination of two separate words, "age" and "structure".
1. "Age" originates from the Latin word "aetatem", which means "a period of time" or "age". It has been used in English since the 13th century.
2. "Structure" comes from the Latin word "structura", which means "a building" or "arrangement". It also has been used in English since the 13th century.
Therefore, when combined, "age structure" refers to the arrangement, distribution, or composition of different age groups within a population or a particular context.
