A name can be rare in one generation and common in another
Enter a first name and choose a year to compare it with the other names recorded for that cohort. The calculator covers 1880–2024 in a pinned snapshot of the Social Security Administration’s national baby-name files. It combines the published female and male counts for each spelling. A rank of #1 means the most frequently recorded spelling in that year, after combining those categories.
The “1 in” figure divides the sum of published name counts by the count for your spelling. It excludes records hidden by SSA’s privacy threshold. That makes it a comparison within the released data, not an exact probability among all U.S. births. The name methodology explains this denominator and the limits of early records.
Compare the same spelling across years
Try a familiar name such as Olivia, James or Taylor. Look it up for 2024, then change the year to 1980 or 2000. A different result describes a different naming cohort; it does not mean people changed their names. Counts can change because both the name’s popularity and the size of the recorded cohort change. The “1 in” figure helps compare cohorts of different sizes.
Case does not matter. Spaces, hyphens and apostrophes are removed for matching the published spelling. We do not guess that two differently spelled names are the same, translate a name, or infer anyone’s identity from it. If a spelling is absent, the tool explains the missing data instead of assigning it a flattering rarity score.
A card with its context attached
Every result can become a story-sized image or a landscape card. The year and the phrase “published baby-name records” stay on the card so someone seeing it elsewhere can understand the comparison. For another part of your name, use the separate surname lookup. For a personal collection, add your birthday and surname to one card. Those facts remain separate because these public files do not measure their joint probability.
Good questions
Does this count everyone alive with my name?
No. It counts published SSA baby-name records for a selected birth year, with both recorded sex categories combined. It does not estimate living people or worldwide name frequency.
Why is my name missing?
SSA suppresses names recorded fewer than five times within a sex category and year, and edits some input spellings. A missing name has unknown frequency here; it is not proof of a unique name or zero occurrences.
Can you check my full name?
The first-name and surname datasets do not link individuals. You can show both facts on a card, but these data cannot tell us how many people share a full name.
