What fewer than 100 births really means
These are exact-spelling counts in the national SSA file. A name with 50 published births was recorded 50 times for girls in 2025 under that spelling. Similar spellings are not combined.
Rare now does not always mean rare historically
Some names on this list have been uncommon for decades, while others had a stronger period in the past. The historical peak beside each name helps show whether 2025 rarity is longstanding or part of a decline.
The public data has a privacy floor
SSA does not publish names with fewer than five occurrences in its national files. If a name is missing, that does not prove zero babies received it. It may simply be below the public reporting threshold.
Rare can still be easy to pronounce
Blythe, Neve, Vita, Clio and Sable are very uncommon by current U.S. counts, yet they are short and visually straightforward. Low usage does not automatically mean a name has to be complicated.
Posy's pick
Cosima
Cosima was recorded for 19 U.S. girls in 2025, making it genuinely rare while still feeling established and wearable.

Questions parents ask
How rare is a name with fewer than 100 births?
In a country the size of the United States, fewer than 100 published girl births in a year is very uncommon. The exact experience still varies by state and community.
Does a missing SSA count mean nobody used the name?
No. SSA suppresses names with fewer than five occurrences in the national public file, so a missing name can mean one to four recorded births.
Are alternate spellings combined?
No. SSA treats different spellings as different names, so Posie and Posey have separate counts.
Can a very rare name have been more popular in the past?
Yes. Current rarity and historical popularity are different. Version 4 shows each listed name’s strongest published year in the SSA archive so you can see that context.
