When the year of birth for a living individual has been researched, but the month and day remain missing, pleasedo not add "Category:Date of birth missing (living people)" to an article before ascertaining said individual's full public prominence. The privacy of marginally-notable "non-public figures" must be respected; seeWP:NPF andWP:BLPPRIVACY. Such people, even if their entire date of birth is available in a public record, should have only their year of birth indicated.

This category is intended for use in biographical entries which indicate the living individual's year of birth, but not the month and day, because of lack of research, availability in areliable source or notation in the relevant article.
