The term "age range" refers to a group or category of individuals who share a common characteristic - their age. It is typically used when describing a population, demographic or statistical data that has been divided into different categories based on age. For example, if you were looking at the age distribution of a particular community, you might break it down into different groups such as "18-25 years", "26-35 years" and so forth. The term can also be used to describe the range or span of ages that an individual may fall within - for example, someone could say they have an age range of 20-40 years old meaning their birthdate falls between those two dates.
