DeCarlo is an Italian surname that has been adopted as a given name by some families over time. The name's origins can be traced back to Italy, where it was used as a nickname for someone who was skilled at playing cards, derived from the Italian word 'decartare' meaning 'to play cards'.
Over the years, the popularity of the name Decarlo has shown fluctuations, with peaks in certain decades and a notable decline in recent years. From 1953 to 1974, there were more than ten births each year, reaching a high of 26 births in 1978. However, from 1975 onwards, the number of annual births began to decrease steadily, with fewer than twenty births occurring each year. This trend continued into the 2000s and beyond, with single-digit numbers of births becoming more common, indicating a significant decline in the name's usage. Despite this, Decarlo is still not an uncommon name, with a total of 635 births recorded over the entire period.
