Countable characteristics of a person, such as age, income, level of education, and others, are considered characteristics of a person or target market, whereas characteristics of a person or target market such as personality, lifestyle, motives and others are classed as variables. Each of these as well as two other classes of characteristics can be used as market segmentation variables.

The correct answer are: demographic characteristics and psychographic characteristics.

Explanation:

Companies generally carry out a market study to get to know their potential clients better. When conducting these studies, companies usually segment people into different groups.

When speaking of segmentation, it refers to dividing the population into different parts, due to different characteristics. There are four segmentations usually used: geographic, demographic, psychographic, and behavioral segmentation.

For example, in the case of the characteristics of people such as age, income, and educational level are considered demographic segmentation, this segmentation is widely used by companies and it is very easy to classify potential customers.

And, when it takes into account characteristics such as personality and lifestyle known as psychographic segmentation, these characteristics help to know clients more specifically.
