Definition of age group

The term "age group" originated in the early 20th century as a statistical classification system used in population studies. It was initially created to analyze demographic data and understand the distribution and trends of populations by age. The concept of age grouping is based on the idea that people at the same age share common experiences, behaviors, and needs. In other words, individuals within the same age group are more likely to be at similar stages of development, education, and career paths. Initially, age grouping focused on broad categories such as birth year decades, such as "0-9 years," "10-19 years," and "20-29 years." These groupings were later refined into more specific age ranges, such as "18-24 years" and "45-54 years," to account for more nuanced characteristics and behaviors associated with particular age periods. Today, age grouping is used in a wide variety of fields, including marketing, research, education, healthcare, and government policy, to understand and respond to the varying needs and preferences of different age cohorts. It allows for more targeted and effective strategies to be developed and implemented, rather than using a one-size-fits-all approach.
