CJ identifies as non-binary, which means they doesn’t recognise themselves as male or female, but part of a third, neutral gender. (Instead of using the pronouns “he” or “she”, the word “they” is a common gender-neutral alternative.) The word “Mx” was first suggested in the late-1970s as a feminist word for those who didn’t want their gender to be revealed in their title, and there are many men and women who use Mx for similar reasons today. However, the title has also become popular among those who identify as non-binary – though there are no official figures, non-binary people make up around 0.4% of the population, according to a Equality and Human Rights Commission survey of 10,000 people in the UK.
