Rhett is a very Southern baby name. Not in the sense that Southerners own it — any parent can use it — but in the sense that a Rhett in Georgia is unremarkable and a Rhett in Seattle is a minor social event. Declan belongs to a belt from Boston to Chicago with high Irish Catholic populations. Caden clusters in the Mountain West. None of this is obvious from looking at the national SSA top 100, because national data does something that seems helpful but is actually obscuring: it averages out the geography.
How SSA Data Reveals — and Hides — Regional Variation
The Social Security Administration publishes state-level baby name data separately from its national files. The national rankings are what most people consult, and they tell a coherent story: here are the most popular names in America, full stop. But the national data is an average of fifty very different conversations happening simultaneously, and the averaging flattens the most interesting variation.
Consider a name that ranks 48th in Texas, 52nd in California, 45th in Florida, but does not crack the top 200 in Minnesota, Michigan, or Oregon. In the national data, that name will land somewhere around 60th or 70th and will appear to be a moderately popular national name. In reality, it is a Sunbelt phenomenon that barely exists in the Upper Midwest. A parent in Minnesota who sees it in a national top-100 list and assumes they will encounter many children with that name has been misled by the aggregation.
The reverse happens too. Names that appear to be minor in national rankings can be genuinely dominant in specific states — a name ranking 200th nationally might be top-30 in Utah, or top-25 in Louisiana, because its popularity is geographically concentrated rather than evenly distributed.
The Religious Geography of Baby Names
One of the most persistent drivers of regional name variation is religious geography. American religious denominations are not randomly distributed — they follow patterns that have been remarkably stable for more than a century, and those patterns show up in naming data.
The Catholic Belt
Names like Declan, Brigid, Colm, Siobhan, and Fionnuala cluster heavily in the Northeast and Great Lakes Midwest, tracking the historical Irish and Italian Catholic settlement patterns. A name like Declan, which has become a moderately popular name nationally, draws a disproportionate share of its births from Massachusetts, Connecticut, New York, New Jersey, and Illinois. It is not that Declan is unheard of in Tennessee — it is just that in Tennessee, it is unusual, while in the Boston suburbs it is a fairly ordinary choice among a certain demographic.
Catholic saint names follow a similar geographic logic. Patrick, Brendan, Kathleen, and the slightly more ornate saint-name tradition (Anastasia, Sebastiano, Gianna) tend to over-index in areas where Catholic institutional culture remains strong.
LDS Naming Patterns in the Intermountain West
Utah and Idaho produce some of the most distinctive regional naming signatures in the United States, driven by the cultural influence of the Church of Jesus Christ of Latter-day Saints. LDS naming tradition has historically favored certain patterns: names from the Book of Mormon (Moroni, Nephi, Alma — though these are now less common), virtue names and nature names, and a distinctive aesthetics around invented or blended names that has spread beyond the LDS community into general Mountain West naming culture. Names with unusual spellings, names that blend existing names into new forms, and certain surname-as-first-name choices that originate in this tradition are detectable in SSA state data.
Southern Baptist Naming Patterns
The Deep South has its own naming signatures that are distinct from both the Catholic Northeast and the LDS West. Old Testament masculinity names (Eli, Elijah, Amos, Silas, Gideon) have long been strong in the Southern Baptist tradition. Virtue and character names — names chosen because of what they mean rather than how they sound — persist here alongside a continued tradition of family name recycling: using a father's or grandfather's surname as a son's first name, which produces the distinctly Southern first-name-as-surname patterns that outside the South can seem elaborate.
Cultural Geography and Ethnic Naming Concentrations
Religious geography and ethnic geography overlap but are not identical. Spanish-origin names — Isabella, Sofia, Santiago, Valentina, Diego — are far more common in California, Texas, New Mexico, Arizona, and Florida than they are in, say, Montana or Vermont. This tracks population demographics, but it also reflects something about naming norms within communities: a name that feels normal and unremarkable in a predominantly Hispanic community will feel marked and somewhat exotic in a community where it is rare.
Scandinavian-origin names (Ingrid, Lars, Bjorn, Astrid) persist in the Upper Midwest — Minnesota, Wisconsin, the Dakotas — in ways that reflect the historical Norwegian and Swedish settlement of those regions. These names are not common nationally, but in pockets of Minnesota, Ingrid is as unremarkable as Emily.
Claude S. Fischer, in Made in America: A Social History of American Culture and Character (2010, University of Chicago Press), argues that regional American cultures have been more persistent than modernization narratives suggest — that the cultural geography set in the nineteenth century by different waves of settlement, migration, and religious organization has continued to shape social behavior far into the twenty-first. Baby names are one of the more sensitive registers of this persistence, because they are chosen privately but shaped by community norms, and community norms are slow to change.
Urban/Rural Name Divergence
The urban/rural divide in baby naming has become more pronounced over the last two decades, and it maps approximately (though not perfectly) onto the coastal/interior divide that shapes so much of American cultural geography.
Names that tend to be labeled "trendy" or "cool" by parenting publications — Milo, Isla, Finn, Cora, Phoebe, Theodore, Ezra — cluster heavily in urban centers and their affluent suburbs. They are real national trends, but they are not evenly distributed national trends. A name that ranks in the top 50 in Brooklyn or Portland may rank outside the top 150 in rural Alabama or small-town Nebraska. The parenting media, which is produced largely in coastal urban centers, tends to treat these names as national trends when they are, more precisely, professional-class urban trends with national ripple effects.
Meanwhile, traditional and Biblical names persist more strongly in rural communities and in smaller cities in the interior. This is not because rural parents are backward or unaware of trends — it is because naming is a social act, and social acts reflect the norms of the community in which they take place. If every family in your church congregation names their sons Elijah and their daughters Grace, Elijah and Grace feel normal, traditional, and right.
The Homogenization Question
Robert Putnam noted in Bowling Alone (2000) that American community bonds were weakening, and a great deal of subsequent research has grappled with how national media culture affects local distinctiveness. The question for baby naming is: has the internet and the rise of national parenting media homogenized regional naming, or are regional pockets as persistent as ever?
The evidence is mixed. On one hand, the top-10 national names are now more likely to appear in every state than they were in 1970 — the extreme outliers (states where a nationally rare name dominates) are rarer. On the other hand, the long tail of naming diversity has grown enormously, and much of that growth is regionally concentrated. The names at the very top have become more universal; the names in the middle of the distribution are, if anything, more regionally specific than ever.
Laura Wattenberg, whose Baby Name Wizard remains the most insightful popular treatment of naming trends, has noted that regional naming variation is one of the most underappreciated dimensions of American name culture — underappreciated because it is invisible in the national data that most parents consult.
What This Means for Name Choice
There is a practical upshot to all of this: the social meaning of a name depends heavily on where you live. Being one of three Rhetts in a Georgia elementary school is a very different experience from being the only Rhett in a Minneapolis school where the name is considered slightly exotic. Both are fine — but they are different.
This cuts both ways. A name that feels refreshingly uncommon in your city might be extremely common in the region you grew up in, or in the community your parents belong to. A name that feels safely traditional to you might read as regional-specific to your new neighbors. The national data tells you what is popular in aggregate. It cannot tell you what is normal in your specific social world — and that gap is where most naming decisions actually live.
