Baby name popularity ranking markets
Each spring the US Social Security Administration publishes the most popular baby names from the previous year, and the release reliably makes headlines. Event markets now ask which name will rank first, whether a rising name will crack the top ten, or whether a name will gain a certain number of places. The data are official and public, but how they are counted matters. This SoftCta guide explains the list and the patterns that make these questions more predictable than they first look.
What the SSA counts
The rankings come from Social Security card applications for US births. Names given to fewer than five babies of a given sex in a year are excluded from public files for privacy. Lists are separate for boys and girls, and the SSA publishes national rankings plus state and territory rankings. Our census guide covers other official demographic data with different methods.
Spellings are separate
The SSA ranks each spelling as its own name. Combined spelling groups might put a name much higher than its official rank, and some media outlets publish combined rankings. A contract using the SSA list follows its separate-spelling rule unless it states otherwise. Also note that sex is reported as recorded on the application.
Release timing
The SSA typically releases the prior year's list in spring, often around early to mid-May, but the date varies. Contracts should state a deadline and what happens if the release is delayed. Occasionally the SSA updates files later as more applications are processed; our revisions guide explains why first release usually settles.
Momentum and slow change
Top names change slowly. A name that has led for several years tends to stay near the top, and rising names usually climb over multiple years. That makes a base rate approach powerful: look at how often the previous year's leader kept first place, and how far names typically move within a year.
Pop culture spikes
Celebrity baby names, popular shows and viral moments can produce sudden jumps for less common names. Those jumps show up most at lower ranks, where small count changes move a name many places. At the very top, counts are large and changes are gradual. Our regression guide explains why last year's fastest riser may slow down.
Rank versus count
A contract asking about rank depends on every other name; a contract asking about count depends on births and naming choices. Total US births change year to year, so counts can fall while rank holds steady. Read which measure is named, and check whether ties are possible and how they are handled, as discussed in our rounding and threshold guide.
A reading habit
Pull the last five years of the SSA list, note each candidate's rank and count trajectory and check the gap between first and second place. A large gap rarely closes in one year. Then compare that history with the market price.

FAQ
- Where do official US baby name rankings come from?
- The Social Security Administration publishes them based on applications for Social Security cards for babies born in the US. It releases national and state lists each year.
- When is the list released?
- The SSA usually releases the previous year's rankings in the spring, often around early to mid-May near Mother's Day. Exact dates vary from year to year.
- Are different spellings combined?
- No. The SSA counts each spelling separately, so names like Aiden and Aidan are ranked as different names. Contracts should say whether they use the official separate-spelling ranking.
- Which names topped recent lists?
- Liam and Olivia were the most popular boy and girl names in the SSA lists for several recent years, including 2023 and 2024. Verify the latest list before reading any current contract.
