Most baby-name lists focus on what’s popular. This map asks a different question: what names are uniquely local?
Some names are spread evenly across the country. Others are so concentrated in a single state that they act like cultural fingerprints, revealing migration patterns, religious communities, regional traditions, and local obsessions.
That’s what this map measures. For every baby name in the Social Security Administration’s records, we compared its popularity in each state to its popularity nationally. A score of 1 means a name is exactly as common there as it is everywhere else. A score of 20 means it’s twenty times more concentrated in that state than you would expect.
The result is one of the strangest maps of America we’ve ever seen. A map of immigration. A map of religion. A map of football. A map of local obsessions, forgotten traditions, and naming cultures that never spread beyond state lines.
Every state has a signature name. Not necessarily its most popular name. Its most local one.
Each state’s most over-represented name since 2000 (location quotient vs. the national rate, minimum 150 births). Tap a state to explore the name. SSA data through 2025.
Browse the map long enough and patterns start to emerge.
The Football Belt
Some states are naming children after football stadiums. Iowa’s signature name is Kinnick. Tennessee’s is Neyland. Both names come directly from the stadiums where their flagship universities play football.
Somewhere along the way, school pride escaped the parking lot and ended up on birth certificates. Alabama’s signature name, Crimson, belongs to the same family of ideas. Many states love football. Only a few love it enough to turn stadiums into baby names.
The Immigration Map
Other signatures trace migration. Minnesota’s most distinctive name is Abdirahman, reflecting the state’s large Somali community. Pennsylvania’s is Benuel, rooted in Amish communities. New Jersey’s is Avrohom. New York’s is Yides. New Mexico’s is Estevan.
These names aren’t random. They reveal communities that are large enough, stable enough, and concentrated enough to leave a visible mark on the naming record. You can almost reconstruct parts of American immigration history without looking at a map. Just follow the names.
Hawaii Breaks the Scale
Most state signatures are five, ten, maybe twenty times more concentrated than the national average. Hawaii is different. Hawaii’s top names often appear hundreds of times more frequently there than on the mainland. Names like Kainalu, Kainoa, Keanu, and Shizue form a naming universe that is uniquely Hawaiian, shaped by Native Hawaiian traditions and generations of Pacific and Asian immigration.
Most states have a naming accent. Hawaii has its own language.
Utah Is Its Own Naming Ecosystem
Then there is Utah. Most states have one or two highly distinctive names. Utah has dozens. Dallin. Ammon. Brigham. Stockton. Brynlee. Some draw from LDS history. Others reflect local naming fashions. Together they form something unusual: a naming culture that consistently generates names more common inside the state than outside it.
No other state behaves quite the same way. Utah isn’t a state with distinctive names. It’s an entire naming ecosystem.
The Frontier Sound
Not every signature comes from immigration, religion, or football. A whole cluster of states share a different kind of name — and it’s the newest cluster on the map.
In the Mountain West and the Plains, the signature names sound less like family heirlooms and more like surnames, places, and the outdoors. Montana’s is Bridger, fifty times more concentrated there than nationally — a name straight out of frontier history. Idaho’s is Oakley. South Dakota’s is Tate, Nebraska’s is Brecken, Wisconsin’s is Cashton, Maine’s is Colby, Vermont’s is Sawyer. Alongside them runs a wave of invented surname-style names — Brynlee in North Dakota, Oaklynn in West Virginia, Kinley in Arkansas.
These aren’t holdovers from a century ago. Most of them barely existed before 2000. They’re a contemporary naming style — rugged, surname-flavored, a little bit Western — that took hold hardest in rural America and never spread as strongly to the coasts. If Hawaii has its own language and Utah its own ecosystem, these states share an accent: the sound of a name that could just as easily be a last name, a small town, or a state park.
What the Map Really Shows
States have official symbols. Birds. Flowers. Flags. Mottos. This map reveals another kind of symbol — an unofficial one. A name that became common enough, local enough, and enduring enough to become part of a state’s identity. Some arrived with immigrants. Some emerged from religious communities. Some came from football stadiums. Some are the newest sound in rural America.
Together they form a second map of America. One hidden in birth certificates. One nobody meant to create. And one that could only have emerged one baby at a time.
