In demographic aging terms, the ‘old-old’ group typically refers to people aged:

• A. 65 to 74 years
• B. 75 to 84 years
• C. 85 years and older
• D. 90 to 99 years

Answer: (C)

Grouping older adults into age cohorts helps clinicians anticipate changes in health needs as people age. The young-old are typically 65–74, the middle-old 75–84, and the old-old begin at 85 and older. Reaching 85 marks a shift in patterns of frailty, chronic disease burden, and functional decline, which is why this group is labeled old-old. Therefore, the age range defining the old-old is 85 years and older. (Some sources further subdivide within 85–99 and 100+, but 85+ is the standard cutoff for this category.)
