Top 10 Baby Names Weren't Strictly Gendered for 80+ Years

For generations, the most popular baby names in America shared a surprising secret: they were, almost without exception, gender-flexible.

On Naymt, every name is color-coded by gender: green indicates a "masculine" name (one that has only ever appeared in the boys' top 1000 since 1880), purple indicates a "feminine" name (only in the girls' top 1000), and yellow indicates a "neutral" name (one that has appeared in the top 1000 for both genders at some point in history).

Naymt's deep dive into over a century of data (1880-1995) has uncovered that a staggering 99.4% of all names that reached the top 10 for either boys or girls were yellow — "neutral." This means that, at some point since 1880, these names had appeared in the top 1000 for *both* genders.

This finding directly challenges our modern perception of 'boy names' and 'girl names.' Consider the classic names that dominated the charts for decades: Mary, Anna, Emma, Elizabeth for girls, and John, William, James, Charles for boys. While these names were overwhelmingly given to one gender, every single one of them also appeared in the top 1000 for the opposite gender at some point in history. Mary, the quintessential girl's name, ranked as high as #211 for boys in 1897. John ranked #227 for girls in 1880.

The implications are profound. For 83 years, from 1880 until 1963, every single name in the girls' top 10 had also, at some point, cracked the boys' top 1000. It wasn't until Lori debuted at #8 in 1963 that a truly "feminine" name — one that has *never* appeared in the boys' top 1000 — finally broke into the elite top 10.

The boys' chart held an even longer streak: 113 years! From 1880 until 1993, every name in the boys' top 10 had also appeared in the girls' top 1000. Jacob, ranking at #9 in 1993, marked the first time a truly "masculine" name — one with no historical record in the girls' top 1000 — made it to the top tier.

Names That Completely Switched Genders

Perhaps the most shocking finding involves names that didn't just cross over — they completely flipped. Ashley has 144 years of male popularity data compared to just 86 years of female data. Yet in 1991 and 1992, Ashley became the #1 most popular name for girls in America. A historically boys' name became the top girls' name.

Madison tells a similar story: 144 years of male data versus only 45 years of female data, yet it reached #2 for girls in 2001-2002. These names didn't just appear on both charts — they fundamentally changed gender identity in public perception.

This historical pattern suggests that parents, for over a century, gravitated towards names with cross-gender precedent. The rise of strictly gendered popular names is a remarkably recent phenomenon.
