Mico is of Latin origin, derived from the word 'micus', meaning 'small'. It was used by the Romans to denote a small, diminutive form, and later adopted as a personal name. Mico is also associated with the Greek mythological figure Micipsa, a king of Numidia who ruled in the 2nd century BC.
The name Mico has had a varied popularity over the years, with peaks in recent decades. Between 2014 and 2023, there were consistently high numbers of babies named Mico, with totals ranging from 8 to 10 births per year. However, prior to this period, the popularity of the name was quite low, with fewer than 7 births recorded in each year between 1970 and 2013. The overall total of 138 births over these years suggests that Mico is not a particularly common name but has seen some recent resurgence in popularity.
