Names 2017: Boys and Girls Together

Boys names can become girls names, rarely the reverse. But that is true only of individual names. With the overall distribution of names, in at least one way, boys are becoming more like girls.

When a name crosses over from one gender to the other, girls follow the boys. A name that had been exclusively male starts to gain popularity for girls, with a consequent loss in popularity for boys.  It’s the “there goes the neighborhood” effect that Stanley Lieberson first pointed out. When girls start moving in, boys move out. (See this post).

For example, around 1960, Brook started to rise in popularity as a name for boys. Barley ten years later, the name was adopted by parents of girls. In a decade this girls  name quintupled in popularity. The number were still small, but where before it was not even in the top thousand, it rose to nearly #500 in popularity. Parents felt they could no longer give a boy that name, and Brook soon became an all-girl neighborhood. With an “e” added, Brooke eventually broke into the top 50, while baby boy Brooks all but disappeared.

But if we look at changing patterns in names —  the variety and variability—  the genders switch places.  The curve of boys names is becoming more girl-like.

Fashions in names have resembled fashions in clothes. Women can wear a variety of colors and styles; men’s choices are more limited. Look at prom pictures. The guys are all wearing pretty much the same black tux. Everyday business wear for men widens the spectrum only slightly. Remember how Obama was pilloried by the right-wing for wearing a tan suit rather than the usual gray or black that all other men wear. But for a woman, it can be an embarrassment to be seen in a dress worn by even one other woman.

Similarly in names, parents of boys were happy to give their sons the same old names —  William, Christopher, John, etc. Boys could be given the same name as the father. But for girls, parents were more likely to want a name that was different (but not too different). One of the trends of the last several decades is that parents of both sexes have tried to come up with less common (but not weird) names.  Consequently the sheer number of different names has burgeoned. Compared with names in 1997, the number of girls names had increase by 60%. But for boys the number had more than doubled. Boys are still trailing girls, but they’re trying to catch up.



The increase in names is not simply a matter of an increase in babies. In fact, more babies were born in 1997 than in 2017.

The trend towards a more female-like variety also appears in the proportion of babies accounted for by the most popular names. Forty years ago, nearly 38% of all boys had a name that was among the 20 most popular. For girls, the corresponding rate was 26%. Parents of girls were more likely to look for less common names.



That trend – the search for more unusual names – increased for both sexes, but more so for boys.  By last year, the boy-girl gap of forty years ago had narrowed to one percentage point.

The desire for something new also means that fashions change more rapidly. Traditionally, women’s clothing styles came and went in a year or two or even in a season while men could keep wearing the first suit they’d ever bought (if it still fit). But fashions in male names (and probably in clothing too) have become more fleeting. Look at the top 20 names for each gender at 20-year intervals.


Of the top 20 boys names in 1997, more than half had been there 20 years earlier. For girls, only five of the top names of 1977 remained in the top 20. Jump ahead twenty years to 2017. Now, among the boys, only 5 names from 20 years earlier are still popular. And for girls, only two — Emily and the surprisingly durable Madison.

The convergence might be part of a general trend towards less rigid gender roles. If so, then the trend towards a greater variation in boys names should be slower in regions that are less evolved when it comes to gender roles. Or perhaps it’s part of the change towards viewing the child as a unique and very special individual, one who deserves a unique and very special name. That change in turn may have a lot to do with the decrease in the number of children. But these are just highly speculative guesses.

UPDATE: Tristan Bridges has much better graphs showing these same trends. He uses the top 10 rather than the top 20 and finds that in 2017, for the first time since 1880 when the census started keeping the count of names, the top 10 girls names accounted for a higher (though only very slightly higher) proportion of all girls names than the corresponding proportion for boys.  His post is here.
