Ricko is of Italian origin, derived from the Latin name Ricchino, which itself is a diminutive form of Riccardo. Riccardo is a variant of Richard, meaning "bold power" or "strong ruler". The name Ricko gained popularity in the mid-20th century and has been used consistently since then. It is often perceived as a casual and friendly name due to its informal nature. Spelling variations include Ricco and Richo, but Ricko remains the most common form.
The name Ricko had its peak popularity between the late 70s and mid-80s with at least five occurrences each year from 1979 to 1983. There was also a spike in the early 90s, with six births recorded in both 1991 and 2003. However, it seems the name's popularity has somewhat waned as there were only five Ricko births recorded in 2019.
