What method involves categorizing people based on measurable statistics such as age or gender?

The method that involves categorizing people based on measurable statistics such as age or gender is known as demographic segmentation. This approach groups individuals into segments based on quantifiable traits, which helps businesses tailor their marketing efforts to specific audiences more effectively. For example, companies often analyze demographic information to determine which products might appeal to different age groups, gender, income levels, or education backgrounds.

By using demographic segmentation, businesses can identify customer needs and preferences, allowing them to design targeted marketing strategies that resonate with specific segments of the population. This method is essential for creating personalized marketing campaigns and ensuring that products or services are aligned with the characteristics of their target audience.
