Affinity is a unique and distinctive female given name of English origin. It is derived from the word 'affinity', which means a natural liking for or attraction to someone or something. The name Affinity was popularized by American author Mary McCarthy's novel "The Group" published in 1963, where one of the main characters shares this name. Prior to this, the name was not widely used and is still considered quite rare today. However, its meaning and uniqueness make it an appealing choice for parents looking for a special and meaningful name for their daughter.
Between 1998 and 2023, the name Affinity was given to a total of 30 children, with no more than 5 babies sharing this name in any year until a notable increase in popularity in 2020 when 8 babies were named Affinity. There is another spike in usage in 2023 with 7 births.
