In 2018, 80 is the most common age for an American (U.S.) Clara who is a registered female with the Social Security Administration. It is the 459th most common female first name for living U.S. citizens.

The name is also used in Sweden, and Denmark. [noted -ed]

This site, as have others, says Clara is the #4 name in France. Knowing that it definitely sounds like a little French girl to me. Even if it didn't originate there, it is certainly used there.
Shouldn't it be listed as a French name as well?

In Germany, Klara is used more often than Clara. [noted -ed]
