A hate crime (also known as a bias-motivated crime or bias crime) is a prejudice-motivated crime which occurs when a perpetrator targets a victim because of their membership (or perceived membership) of a certain social group or racial demographic. Examples of such groups can include, and are almost exclusively limited to ethnicity, disability, language, nationality, physical appearance, religion, gender identity or sexual orientation. Non-criminal actions that are motivated by these reasons are often called "bias incidents".
