Answer:A social category
Explanation:A social category is a collective number of people who all have similar characteristics eventhough they don't interact. For example, women, men, the elderly, and college school students all fall under social categories. A social category can transform or convert into a social group if people under social category start to interact with each other.
People who are found in the same place and who have similar characteristics but who do not interact are called social aggregates.
