Carlos Javier is of Spanish origin, composed of two names that are often used together. 'Carlos' is derived from the Germanic name 'Charles', which means 'free man'. 'Javier' is a Spanish derivative of 'Xavier', which is ultimately derived from the Basque name 'Etcheberri', meaning 'new house'. The full name Carlos Javier was popularized by Saint Francis Xavier, one of the co-founders of the Society of Jesus (Jesuits), and thus has strong associations with faith and spirituality.
The name Carlosjavier has been a rare choice for parents in the United States, with only five babies being given this name each year since its first appearance in the Social Security Administration's record-keeping in 1998. Over two decades later, the total number of births registered under the name Carlosjavier remains at just fifty. This unique and distinctive name has been consistently uncommon among newborns across the United States.
