Classification of gender, variant

Usage

Given that the non-binary population is small, data aggregation to a two-category gender variable is sometimes necessary for confidentiality and data quality reasons. In these cases, individuals in the category "non-binary persons" are randomly recoded into the other two gender categories and are denoted by the "+" symbol. This note should be included whenever the two-category gender variable is used.

In analytical products, using "men" and "women" without the "+" symbol, rather than "men+" and "women+", in the main text is preferred to improve readability and avoid giving the impression that "men+" and "women+" are part of a new standardized naming convention for the people represented by these categories, when no such naming convention has been established.
