Ivars is of Scandinavian origin, derived from the Old Norse 'Ivarr', which means 'archer'. It was popular among the Vikings and was borne by several notable figures, including Ivar the Boneless, a 9th-century Viking chieftain who played a significant role in the expansion of Norse influence into England. The name Ivars has been used throughout Scandinavia for centuries but is less common elsewhere.
The name Ivars experienced a decline in popularity between 1954 and 1966, with the highest number of births occurring in 1954 (11) and the lowest in 1959 (5). The total number of births over this period was 28.
