    > Of the 42 names that moved toward girls, 34 were driven mainly by an increase among girls, rather than a decline among boys.

    > Surprisingly, the same pattern held in the opposite direction. Of the 12 names that moved toward boys, 9 shifted mainly because fewer girls were receiving them, rather than because more boys were. In other words, whichever way a name moved, the biggest change usually came from girls.

    This is consistent with the observation that girl's names are more dynamic.

      I have no data but feel that boys tend to get the family names and biblical names (in US anyways). It's rare to hear of a girl named Elizabeth III or Mary Junior but quite common for those concepts in boys. So I think the boy names are heavily weighted on probably the most popular ~25 or so names. Since girl names are more free to follow whatever is fashionable at the time, trends move faster.

      My son is named after his grandfather, and it's an overly common name in English (American and British). Definitely a top 3 most common for last several centuries

        Anecdata: I’m a guy and a III. My son almost was a IV but we chose another first name and used my (and my dad’s and my grandfather’s) name for his middle name. My great grandfather had a different name, but I think his dad and maybe grandfather had the same name as me.

      It seems there are lots of cases across the board where "women adopt traditionally male thing" has become the norm in this timeframe but not many where "men adopt traditionally female thing" at quite the same rate or scale.

      Interesting, I wonder what causes this? In the US, is more common to name the first son after the father. Given this data comes from US social security information, that definitely has an impact.

    There are a few names I think are being confused. Jan, short for Janice is a female name, but Jan in Central / Eastern Europe as a form of John is masculine. Jean the female name and Jean the french male name are different.
    • cvhc 34 minutes ago
      Yeah immigration and mix of similar names from different languages could also be reasons for the (at least perceived) shifts.
      • nostrademons 18 minutes ago
        This is part of what they mean by girl names driving the shift. You have a traditional ethnic name that may be masculine or feminine and has a baseline low level of popularity. Then you have a popular female name that rapidly gains and loses its popularity. The effect on the mix is that it's shifting from masculine to feminine, but really you should look at it as a newly-popular female name being layered on top of the traditional name. And you can often see this in the timescale, with a clear pop-culture trigger leading to the rising girl name.

        Looking at just part of the data, I can see this with Arya (Stark, Game of Thrones), Paris (Hilton), Stevie (Nicks, of Fleetwood Mac), Dakota (Fanning), and Tatum (O'neal), and the masculine trend also relates to the fading of generationally-popular names like Jean (Silent/Boomer), Pat (Boomer), Joan (Silent/Boomer), Courtney (Gen-X/Xennial), etc.

    There was a guy at my school named Hilary who got awful abuse for it. Always wondered why parents would do such a thing to a child.
    • snarf21 2 minutes ago
      As someone with an pretty unusual name, I think kids will always find a reason to make fun of you and it isn't always just the name.

      True Story: My mom was a 2nd grade teacher for 30 years and in the 70s had a student with very 'hippie" style parents. They named their son Log Cabin. You can imagine how that went over in elementary school.

    • LorenPechtel 22 minutes ago
      I suspect this is a big driver of the switch. Parents that do not want to give their boys a name that will cause issues later on.

      Back in school it wasn't a problem, people knew "Loren" was male, "Lauren" was female. Now, an awful lot of people don't. It's an uncommon enough name that even if you were around back when that's how it worked you very well might not have known it.

      As an adult I routinely get misgendered, but it's a so-what to me.

      • lrivers 1 minute ago
        Loren adjacent. In high school my girlfriend was Lauren and mine is Lorin. Friends over pronounced our names to differentiate. It doesn’t bother me to get misgendered, either. It never lasts past hearing my voice or seeing me, though.

        Here's my favorite "Lauren"*: https://en.wikipedia.org/wiki/Lauren_Bush

        *solely because her legal, married name is Lauren Bush Lauren. She actually changed it, which is gold (and honestly very sweet).

      Weird comment, given that it was, not long ago, a common name for a male.

      I'd wager if it weren't for Clinton, most people would still associate it with men.

      • zahlman 27 minutes ago
        How "not long ago" are you thinking of? Clinton was first a major figure in the 90s (and we also had https://en.wikipedia.org/wiki/The_Fresh_Prince_of_Bel-Air ). And Clinton herself is from the baby boom generation; what male Hil(l)arys from that cohort do you have in mind?
        • zamadatix 20 minutes ago
          Looks like it flipped in ~the 40s, by the ~60s had become rarer as a male name, and was pretty much a flop as a male name after the ~80s. So Clinton was born just when it started to take off for females (and in general - it was never as common as a male name) and there should have been in the same ballpark as as many male "Hilary"s of the same age.

      It's kind of surprising that this is even allowed. A lot of countries require at least the first given name to match the gender. Some names might be deemed suitable for both genders.
      • Vrondi 2 minutes ago
        In the USA, you can name your kid what you want. This avoids one ethnic group requiring everyone to have a name from their tradition.
      • triceratops 13 minutes ago
        We associate names ending with a vowel sound with the female gender. Other than that there's nothing gendered about "Hilary" as a first name.
      • zahlman 26 minutes ago
        …Why would it be surprising for the USA not to have such a requirement?
      • Jtsummers 33 minutes ago
        https://en.wikipedia.org/wiki/Hilary_(name) - It's not an exclusively female name. But in the US, you can give a kid pretty much any name you want (see the names Musk gives his kids these days).
  • Fnoord 1 hour ago
    My biggest WTF on this (as a foreigner) was the late Lindsey Graham. I always knew Lindsey/Lindsay as a female name.

    Either way, peeking through the list, seems to me names which end with a vowel are usually feminine. However, there's a caveat: names end up shortened, and over time even those get shortened.

    'Brit', 'Britney' for 'Brittany'.

    'Gerry' or 'Geri' or 'Ger' for 'Gareth' (Dutch variant: 'Gerrit'),

    'Pat', 'Patty' for 'Patrick', 'Patricia'.

    'Pen', 'Penny' for 'Penelope'

    'Ash' for 'Ashley'.

    'Tash' or 'Tasha' for 'Natasha', 'Nata(s)cha' (a variant of Nathan/Nathaniel?)

    'Toni', 'Tony', or 'Ton' for 'Antonia', 'Anton', or 'Antonius'.

    Skimming through the quick examples I came up with, one thing stands out: if it ends with an 'a', feminine. I believe this stems from Latin? It also appears Brittany is a very British example, whereas say 'Tony' stems from a Catholic background. People with that background get very traditional names, but they're always practically shortened. Annoyingly, you'd have to mention your complete name on say a form, but otherwise you get a wider choice since you have like three names, and they're relatively long so more variety to pick from.

    • triceratops 1 minute ago
      Lindsey (as well as Ashley, Tracy, Kelly, among others) are all, I believe, last names that became given names. They skewed female over time because they end with a vowel.

      Ashley Williams is the name of two American actresses as well as two male soccer players (Welsh and Liberian) and a male boxer (also Welsh).

    • Groxx 12 minutes ago
      Ends in 'a' = female: a relatively safe assumption, as far as an assumption here can be safe, with no other context. A strong majority in many places will match that. Many of the exceptions will be obviously foreign names with traditional spelling, which can go either way (may follow that culture's patterns, may not, highly varied).

      Ends in vowel = female: probably mostly true, in that it may be >50%, but it's unreliable enough that I'd avoid trying to base any assumptions off it.

      Names really follow no rules at all here. For both good and bad. E.g. most recently I ran across a "La-sia" pronounced "ladashsia". If it's spelled vat-ik'Nff and pronounced "King George" and they're female, then that's what's correct.

      Andrea, Simone, Nicola, Michele, Daniele in Italian are all male names, but English speakers would probably assume the person is female from the name alone.

    I feel like a lot of these can be tied to one famous person with the name causing the gender to flip.
  • sota_pop 33 minutes ago
    Most interesting thing that stands out to me is the number of names that appear to be what I would consider an abbreviation of a more traditional name.

    e.g. “Pat” is cited, but doesn’t specify whether that refers to Patricia or Patrick.

    • twoodfin 26 minutes ago
      These are presumably from Social Security registrations, so reflecting official given names.

      Another interesting analysis would be the movement back and forth between full names and their associated common diminutives.

    It's super hard to keep track of, I have an app that's designed to help couples name their baby, and I always wanted to stay away from hard-defined gender stuff, but people still want boy/girl categories. So many are both, but to varying degrees. I ended up using a boy/girl/unisex selector, and had Jev tag all the names. It's especially when dealing with other countries, languages, and customs. At the end of the day, it's mostly easier for the user to just swipe left on a name rather than try to pre-eliminate it from their pool.
  • rolandog 41 minutes ago
    I was very much shocked to see a feminine version of my name used IIRC on Dead Or Alive 4 (DOA4), not knowing the backstory: I think it was a character called Leon was promising to avenge his dead girlfriend, Rolande.

    I've wondered if the women that have carried the name have liked it? In my mind, it's always sounded very blunt so as to be feminine, but I recognize I'm heavily biased when it comes to my own name.

    I’d be curious if men with female names get rejected out of a lot of job interviews since the employer may have thought they chose a female for DEI and then a man shows up?

    Or maybe it’s a good way to get your foot in the door in todays job market.

    • lkramer 25 minutes ago

    A name I was surprised by was someone I know naming their daughter Miles/Myles, which is such a male name in my mind. It might even be based on the Latin word for soldier. It's not one I've seen used for a girl anywhere else, yet.
    • Terr_ 28 minutes ago
      Edited slightly for series spoilers:

      > "Well, I wish you every joy," Miles went on [...] He managed a wink. "Name the first one after me, eh?"

      > [She] grinned. "I'm not sure she'd appreciate that. Milesanna? Milesia?"

      > "Milesia sounds like a disease," Miles admitted, taken aback. "In that case, don't. I wouldn't want her to grow up hating me in absentia."

      -- Memory (1996) by Lois McMaster Bujold

      In the series, Miles' parents knew what they were risking when they gave him a name that meant "soldier."

    Most surprising was "Mario" becoming shared. "Maria/Mario" seemed inherently gendered, based on the last letter.
    • brewmarche 12 minutes ago
      Interestingly if I remember correctly they have different origins, Maria is a biblical name, while Mario comes from Latin (which can decline Marius to Maria, but that’s a different word)
    • bhouston 47 minutes ago
      I think it says "Marlo"? Not "Mario". L, not I.
      • fsckboy 38 minutes ago
        Marlo/Marla is also inherently gendered

        for people from languages that mark gender with an ending (romance languages for instance), putting the "wrong" ending something like a noun would sound odd or change the meaning

        Years ago, one of the broadcasters for a Red Sox game was doing some ad read about some event Stevie Nicks was going to be at, but they read her name as "Steve Nicks" instead. Someone else in the booth corrected them, and they responded "I know him well, and I call him Steve". A fan apparently sent them a giant poster of Stevie Nicks, and the others put it up in the booth and teased him about it relentlessly during the next game.

      In the US, boys would abbreviate Stephen or Steven to Steve. Stevie only for a young boy.

      I’m not sure what they are measuring here though - if it’s only birth certificates then I’m sure Stevie is dominated by girls for a long time.

    • deathanatos 1 hour ago
      With the shift happening right after the 1976–1980 square, I'd assume people named their daughter after Stevie Nicks.
    • Fnoord 1 hour ago
      I mean, this is US-centric data, but it is probably a shortening of 'Stephanie' or 'Stefanie' [1], the female variant of 'Stephan' or 'Stefan'. It stems from Greek, apparently: Stephanos. Its variant are used entirely throughout Europe, from Portugal to Russia.

    Sort of reminds me of the color swap of Pink and Blue for Men and Women.
    • xdennis 13 minutes ago
      You're the victim of misinformation.

      In the past there were no hard associations between sexes and gender and it was possible to find boys wearing some pink clothing, but it was never the case that people associated pink with boys and blue with girls.

      There are some limited examples that contribute to the misunderstanding. For example blue is often associated with the Virgin Mary and red (not pink) was considered a manly color often worn by warriors (e.g. the British, the Romans, etc).

      ---

      This is essentially the way reporting works. If you write an article showing that in the past it wouldn't have been bizarre for boys to wear pink you don't get much traction. But if you write how pink was actually worn by boys and it was considered shocking for girls to wear it, then people find that very surprising and you get a lot of views (truth be damned).

      I'm not sure what you mean by "natural" coloring, but the association you're describing has also reversed over time; i.e., pink was considered masculine and blue was considered feminine.

        I have heard and I do believe that there are countries that use other colors for babies, but wouldn't trust wikipedia nor its selective sources on any topic like gender; wikipedia is no longer enslaved to the truth.
        • boston_clone 5 minutes ago
          You absolutely should trust wikipedia unless you can provide some evidence to the contrary; in fact, the linked article even has a whole section to support your doubt about the claim, which was interesting to read!

          From: https://en.wikipedia.org/wiki/Gendered_associations_of_pink_...

          > In a 2017 letter to Archives of Sexual Behavior, researcher Marco Del Giudice commented on earlier claims about a supposed shift in pink–blue color associations or preferences sometime around the 1940s, from pink for boys and blue for girls before that period, to the opposite alignment afterward. He summarized his earlier work from 2012 which found "no evidence of either reversed or inconsistent usage prior to the 1940s".[41] Del Giudice called this theory the "Pink–blue reversal" (PBR), and said it was "usually attributed to [Jo] Paoletti", and quoted from five academic articles that reprised the theory of "pink is for boys" prior to the 1940s. However, he found upon analysis that it was exceptionally difficult to actually document such a shift, and exclaimed upon "the thinness of the evidence presented in support of the PBR".[42]

          > In his 2012 paper, Del Giudice quoted from four articles published in academic journals which all echoed the claims about PBR theory, many relying on Paoletti, including Chiu et al., 2006: "Prior to that decade, Paoletti ... noted that the sex-dimorphic color coding of pink and blue was inverted, i.e., infant boys were dressed in pink and infant girls were dressed in blue";[43] Frassanito & Pettorini (2008): "At one point, pink was considered more of a boy's color ... blue was considered more for girls";[44] Cohen (2013): "the current stereotypical American assignment of pink to girls and blue to boys was reversed a century ago";[45] and Zucker (2005): "Yet, in the first two decades of the twentieth century, there is evidence that the gender-dimorphic nature of these two colors was inverted, that is, blue was judged to be stereotypically feminine whereas pink was judged to be stereotypically masculine."[46][47] But Paoletti never made the claim that pink and blue reversed, only that there was inconsistent usage that took until the 1950s to resolve[42] starting from the first appearances of gendered pink and blue color associations around the 1860s.[7]
