I got curious and started digging through the Social Security Administration's baby name database.
They registered 3,305,259 baby names during 2020. E.g. there were 17,547 babies named Olivia and 19,690 babies named Liam. They also record these babies as F or M so we know that Olivia was 17,535 F to 12 M and Liam was 19,659 M to 31 F.
