Jackson, an English surname-turned-given-name, was originally a patronymic name meaning "son of Jack." It has appeared in the Social Security Administration's top 1,000 for boy names every year since 1900, but didn't enter the top-100 until 1999. Jack was a top-25 boy's name every year between 2013 and 2022 before falling to 28th in 2023. Unlike most names today, it's just as popular as a given name as it is a surname.
