Baby Names by State: How Regional Taste Shows Up in the SSA Data
How to read SSA state-level baby name files: why small states look noisier, and how region shapes naming taste across the US.
The Social Security Administration does not just publish one national list of baby names. It also breaks births down by state, year by year, going back decades. Pull up any state's file and you'll see something the national top ten never shows: real regional taste, with its own history and quirks.
A name can sit comfortably in a state's top twenty for years while barely registering nationally. Another can top the national list while missing the top spot in most individual states, because a truly dominant name ranks highly almost everywhere rather than dominating a handful of places.
This guide covers what the state files contain, why smaller states produce noisier rankings, and what patterns show up when you compare regions: the Southwest and Florida, Louisiana, Utah and the Mountain West, the South, and the Northeast and Pacific Northwest. None of it requires guessing; it's sitting in public data, and our tools let you look it up directly.
What's Actually in a State-Level File
The SSA's state files work like the national file, with one restriction: a name only appears for a given state and year if it had five or more births there. Anything below that is left out, for privacy, not because the name didn't happen. Our guide to how the Social Security baby name data works covers the national file in more depth; the state files follow the same rules on a smaller pool.
That threshold matters more than it sounds. In a state like California or Texas, with hundreds of thousands of births a year, five is a trivial floor and almost every name clears it. In a state like Wyoming or Vermont, five births can land a name in the top fifty, and a name genuinely common nationally might not clear the floor in a slow year.
This is also why state rankings jump around more than the national list. The national list draws on roughly four million births a year, so it smooths out over time. A small state's list draws from a few thousand, so a handful of families choosing the same name, or not, can shift a rank by ten or twenty spots. A jump from thirty-fifth to eighth in a small state is often noise; in a large state, it's worth notice.
Why the National Number One Isn't Always Number One Anywhere in Particular
Here's a pattern that trips people up: the name sitting at number one nationally is often not the top name in most individual states. Liam and Olivia have led the national SSA list in recent years and rank highly in a wide range of states, but "highly" and "number one everywhere" are different claims.
A name becomes the national number one by being popular broadly, solidly liked in the Northeast, the South, the Midwest, and the West, without necessarily being the single most-chosen name in any region. A name beloved in one region but only moderately popular elsewhere can lose out nationally to a name that's the reliable second or third choice everywhere.
Our name popularity tool charts a name's full history back to 1880, making the difference between broadly liked and regionally beloved easier to see.
Regional Patterns You Can See in the Data
None of these patterns are secret. They show up consistently enough in state-level SSA files, and in reporting built on them, to be worth knowing before you compare states yourself.
| Region | What shows up in the data | Likely driver |
|---|---|---|
| Southwest and Florida | More Spanish-origin names, such as Sofia, Mateo, Camila, and Santiago | Larger Hispanic and Latino populations in Texas, Arizona, New Mexico, and Florida |
| Louisiana | French-influenced first names, plus surnames rooted in Cajun and Creole heritage | The state's French and Francophone colonial history |
| Utah and the Mountain West | Earlier, heavier uptake of newer or less conventional names | Utah parents adopting novel names ahead of the national curve, widely noted in data journalism on SSA records |
| The South | A continued taste for traditional, biblical, and double first names, such as Mary Kate or Anna Grace | A long-standing regional naming convention predating the SSA data itself |
| Northeast and Pacific Northwest | A lean toward classic and literary names, such as Charlotte, Henry, Eleanor, and Atticus | Naming trends that tend to surface here before spreading nationally |
These are regional leanings, not rules. Every state in the South has plenty of Olivias and Liams; every state in the Northeast has parents choosing Spanish-origin or novel names. Regional taste shows up as a shift in proportion, not a wall around a state's list.
It's also worth separating early adopter from trendsetter with a state like Utah. Being ahead of the curve on newer names doesn't mean the state invents them; Utah parents tend to pick up a rising name a year or two before the rest of the country.

How to Read a State List Without Over-Interpreting It
A state's top-ten list looks exactly like the national one, which tempts people to read it the same way. A short set of habits keeps a state list honest:
- Check the state's total annual births before reading much into a rank change. A jump means something different in a state with forty thousand births a year than in one with two thousand.
- Look at a few years of data, not just one; three or four years moving the same direction is a pattern, not an outlier.
- Remember the five-birth floor. A name's absence from a small state's list doesn't mean nobody there chose it.
- Compare a state to its region, not just to the national list. A name unusual against the national top ten might be ordinary against its neighbors.
A Name Can Be Common in One State and Rare Almost Everywhere Else
This is the flip side of regional taste: a name can sit inside a state's top fifty for years while remaining genuinely rare nationally. A name with deep roots in one state's population, tied to language, heritage, or local naming tradition, can clear the state-level threshold there while never coming close to the national list.
If you're curious whether a name is genuinely rare or just underrepresented in the places you happen to know, our name rarity checker estimates how many living Americans share it, with a one-in-N rarity score. To see how many people share a specific full name, the How Many of Me tool draws on SSA birth records and Census surname counts.
A name being locally common today doesn't guarantee it stays that way, either. Plenty of once-fixture names have faded to near-disappearance nationally; our piece on America's disappearing names covers several examples.
Comparing the National Top 100 to What Regions Actually Choose
The clearest way to see regional taste in action is to hold a state's list next to the national one and note where they diverge. Most names in a state's top twenty also appear somewhere in the national top hundred; the interesting cases show up prominently in one state and barely at all nationally, or the reverse.
If you haven't looked at the national picture recently, our breakdown of what the current top 100 baby names actually look like is a solid baseline to compare any state's list against. Once you have it, a state's quirks jump out fast: double names on a Southern state's list, an early arrival for a newly popular name in a Mountain West state, or a French-rooted name's steady presence in Louisiana's rankings.
Frequently Asked Questions
Does the SSA publish a name if only one or two babies had it in a state?
No. State-level files only include a name for a given state and year if it had five or more births there. Names below that are omitted for privacy, so a state's list undercounts rare names rather than proving they didn't happen.
Why does a small state's baby name ranking change so much from year to year?
Small states have fewer total births, so a handful of families choosing, or not choosing, the same name can swing a rank by many spots. A change that would take thousands of births in a large state can happen with a few dozen in a small one.
Is the national number one baby name always the top name in most states?
Not necessarily. A name reaches the national top spot by being solidly popular across the whole country, not by dominating any one region, so it commonly ranks well without being the top name in most individual states.
Why do Utah and other Mountain West states show up so often in naming-trend stories?
State-level SSA data has repeatedly shown Utah parents adopting newer or less conventional names earlier than most of the country. That's an observed pattern in the birth records, not evidence the state invents naming trends; it tends to pick them up, or drop them, ahead of the curve.
Can a name be popular in one state and essentially unheard of in another?
Yes. A name tied to a state's language, heritage, or local naming customs can sit comfortably in that state's rankings while staying rare nationally. Our rarity checker shows roughly how uncommon a name is at the national level.
How far back does state-level SSA baby name data go?
The SSA's state files follow the same span as the national data, starting in 1880 and continuing through the most recent complete year. Coverage improves in earlier decades as more states are included, so the most reliable comparisons tend to come from recent decades onward.
