Dwan is a unique, unisex given name of recent origin, with no known historical or linguistic roots. Its popularity can be attributed to its distinctive sound and the growing trend of choosing uncommon names for children in modern times.
The name Dwan experienced significant fluctuations in popularity over the decades, with a notable peak in the late 1970s and early 1980s. The highest number of births recorded was 66 in 1983, which is more than double the previous highest year (51 births in 1976). However, after this peak, the popularity of the name Dwan declined sharply and has remained relatively low since the late 1980s. The most recent years with data available (2016-2017, 2023) show a total of just 15 births combined, indicating that the name's usage has become quite uncommon in recent times.
