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. Researchers at BabyCenter then analyzed the top 500 baby names for each gender to determine which names had the “steepest year-over-year declines” and their popularity rankings in 2022.

For boys, BabyCenter reported that baby names that start with the letter “K” seem to be “falling out of favor,” including Khalid, Kian, Kyle and Kobe.

For girls, BabyCenter reported that baby names Hayden, Ariyah, Mira, Kate and Katherine had some of the steepest popularity declines from 2021 to 2022.
