It sounds like you're asking, "How old are you in college?" or "How old are people typically when they are in college?" Most people in the United States start college around 18 years old, right after finishing high school. So, during college, they are usually between 18 and 22 years old if they are pursuing a typical four-year undergraduate degree. However, ages can vary widely as some people start college earlier or later, or attend part-time. If you meant something else, feel free to clarify!
