What do you call people who don't socialize

[IdeaGenius]

"Hey everyone,
I'm hoping you can help me out. I'm trying to understand what people call those who don't socialize. I know there are many different labels that can be used to describe people who don't socialize, but I'm not sure which ones are most commonly used. Can someone explain the most popular labels for people who don't socialize? Any help would be appreciated.

People who do not socialize are often referred to as loners, introverts, or recluses. Loners enjoy their own company and do not usually feel the need to spend time with other people. Introverts are more likely to keep to themselves and prefer to interact with others on a limited basis. Recluses are usually very private people who prefer to be alone and may not have any close friends or family.
