The popularity of a baby name can fluctuate with time, but some names are reportedly at risk of "going extinct" in 2023 – at least that’s what one parenting resource is suggesting in a new report.

BabyCenter, an online media company under the Everyday Health Group – Pregnancy & Parenting (EHG P&P), released a baby name report titled "Baby names at risk of extinction in 2023" on Jan. 24, which analyzed naming trends in the top 500 boy and girl baby names.

The top 500 lists – also known as its State of Baby Names initiative – were created from responses BabyCenter received from parents who welcomed newborns in 2021 and 2022, according to the report’s disclosed methodology.
