In gerontology, which trio of terms is used to describe the 'old'?

• A. Young-Old, Middle-Old, Old-Old
• B. Social Security Recipient, Non-Social Security Recipient
• C. Old, Older, Oldest
• D. Young, Middle, Old

Answer: (D)

Age segmentation within the older population uses three descriptors: young-old, middle-old, and old-old. This framework recognizes that those who are considered older are not a uniform group; they differ in health, independence, and care needs. Typically, young-old covers roughly 65–74, middle-old 75–84, and old-old 85 and up. Using these hyphenated terms helps professionals tailor interventions and supports to more specific levels of functioning, rather than treating all older adults as the same. The other phrasing describes life stages across the entire lifespan or relies on less precise labels, which is why the standard trio for describing the old is the young-old, middle-old, and old-old.
