A manager groups consumers by age ranges to investigate differences in product preferences. Which demographic idea is being used?

### Why this is right Age categories group people into named stages, such as infants, teenagers, and senior citizens, which may have distinct preferences. A statistical spread of ages is an age distribution. ### The concept Demographic analysis studies population characteristics. Managers may use age categories to understand differences among groups, or age distributions to study how a population is spread across ages. These are related but not interchangeable descriptions. ### The other options - **B. Age distribution**: This describes the statistical spread of ages, not the grouping label itself. - **C. Political stability**: This concerns consistency and reliability in the political environment. - **D. Natural environment**: This concerns physical conditions and natural resources. ### Watch out A named group and the statistical spread across ages answer different questions. ### Terms - **Demographic**: Relating to population characteristics, such as age or sex. ### Remember A category names a group; a distribution describes how ages are spread.
