Which term means the dynamic balance of a population?

• A. Frail Elderly
• B. Old-Old
• C. IADLs
• D. Demographic

Answer: (D)

This question is about naming the study of how a population changes over time. The term that captures the dynamic balance of a population—its size, age structure, and composition as they shift due to births, deaths, and migrations—is demographic (or demographics). So this option best fits because it refers to those population characteristics and their changes, not to a specific subgroup or a functional measure. The other terms point to a particular group of people (frail elderly, old-old) or to a measure of daily living tasks (IADLs), not to the broader concept of how populations change.
