Jimmi is of Scandinavian origin, derived from the Old Norse 'Jónmadr', which was used as a personal name in Norway and Sweden during the Middle Ages. It means 'hear' or 'to hear'. The name gained popularity during the Viking Age due to its association with the Norse god Thor, who was known for his thunderous power and ability to 'hear' the needs of those who called upon him. Today, Jimmi is often considered a more modern and casual version of the classic James or John.
The name Jimmi appears to have seen its peak popularity between the mid-70s and early 80s with notable spikes in 1972 (13 births) and 1974 (9 births). However, it has remained consistently popular since then, with an average of around 5 births per year from the late 80s to the early 2000s.
