\begin{tabular}{l} Question 9 \\ Demographic Segmentation groups consumers according to: \\ \hline spending habits \\ O physical location \\ \hline age, income, gender, race, education and occupation \\ O number of employees, number of customers, number of offices, or annual revenue \\ \hline\end{tabular}

To solve the question regarding demographic segmentation, we need to identify which option correctly describes the criteria used in demographic segmentation. Demographic segmentation typically involves categorizing consumers based on measurable characteristics. The known conditions for demographic segmentation include: 1. **Age**: Different age groups may have different preferences and spending habits. 2. **Income**: Income levels can influence purchasing power and consumer behavior. 3. **Gender**: Males and females may have different preferences and needs. 4. **Race**: Cultural background can affect consumer behavior and preferences. 5. **Education**: Education level can influence product choices and brand loyalty. 6. **Occupation**: Different professions may have varying needs and spending habits. Now, let's analyze the options provided: 1. **Spending habits**: This is more related to behavioral segmentation rather than demographic segmentation. 2. **Physical location**: This pertains to geographic segmentation, not demographic. 3. **Age, income, gender, race, education, and occupation**: This option includes all the key characteristics that define demographic segmentation. 4. **Number of employees, number of customers, number of offices, or annual revenue**: This relates to business segmentation or firmographics, not demographic segmentation. Based on this analysis, the correct answer is: **Age, income, gender, race, education, and occupation.**
