Two of the names that saw marked increases in usage last year, Luca and Raya, were helped along by the animated films Luca (2021) and Raya and the Last Dragon (2021).

And the name Lilibet re-surfaced in the data (after a seven-year absence) with eight baby girls, no doubt thanks to the royal influence of Prince Harry’s daughter Lilibet, who was born in California in June of 2021.

P.S. The ongoing rise of the baby name Mabel accelerated in the late 2010s thanks to mononymous English singer/songwriter Mabel — who just so happens to be the niece of Eagle-Eye Cherry.
