A very popular name for babies in Italy, Chiara is very rare in the United States, probably because its likely to be mispronounced. Nevertheless, 111 baby girls born in the US in 2012 were given the name Chiara.
In Italy Chiara was not much common in the past, today it has become overused: it was the 7th most popular name in Rome in 1981, 1986 and 1991, the 4th in 1994 (behind Giulia, Francesca and Federica); the 3rd in all Italy in 2004 (behind Giulia and Martina) and the 5th in 2006 (behind Giulia, Sara, Sofia and Martina).
