In 2018, 53 is the most common age for an American (U.S.) Wanda who is registered female with the Social Security Administration. It is the 238th most common female first name for living U.S. citizens.
Wanda first appeared in the top 1,000 names in the United States in the 1880s, perhaps owing to the Ouida novel 'Wanda' which was written and published in 1883, and the name rose from there to its peak of popularity in 1930 (50th position). However, in recent decades the name tailed off somewhat, and has once again been out of the top 1,000 names since the early 1990s. The 1988 film 'A Fish Called Wanda' cannot have helped!
