The term Other White is a classification of ethnicity in the United Kingdom and has been used in documents such as the 2001 UK Census to describe people who self-identify as white persons who are neither British nor Irish. The category does not comprise a single ethnic group but is instead a method of identification for white people who are not represented by other white census categories. This means that the Other White group contains a diverse collection of people with different countries of birth, religions and languages. Along with White British and White Irish, the category does not appear in Northern Ireland, where only one single "White" classification was presented to respondents.
