The term "age range" refers to the span of ages that a particular group or category encompasses. It is often used in various contexts, such as in marketing, education, and research, to define the target audience or participants. For example, a toy might be designed for children aged 3 to 5 years, indicating that it is suitable for that specific age group. In demographics, age ranges help in analyzing population trends and behaviors. Researchers might categorize individuals into age ranges like 0-12 years, 13-19 years, or 20-64 years to study different life stages and their associated characteristics. This classification aids in understanding social, economic, and health-related issues.
