I’ve taken a particular interest in names since I’m thinking of a name for my to-be-born son. I did a little digging through the Social Security Administration names database, which lists all names given to baby boys and girls in America1. I began this exercise to just get a quality list of ideas, but my curiosity got the better of me.

The Recent Top Names Back to 1880

Let’s dive into the boy names who achieved top 1 status since 1950: For a while there, boy names that became popular were at one point in the past popular. However, there seems to be a new trend among millennial parents with a name like Liam coming out of nowhere…

Female names follow a completely different track. Once a name becomes popular, it falls off a cliff years later. Girl names come and go. This plot kind of looks like long hair…a fashion choice common among women?

Wow - Emma made a huge comeback. To go through such a decline, and then see such a resurgence to the coveted #1 spot - the other names must be jealous. And it’s pretty crazy that Mary held on to 1st place from 1880 through pretty much the 1960’s. Part of me wonders how accurate the SSA data is going that far back2.

Uniqueness in the Name

So, I think it’s obvious from above, but just one more check: which sex is more creative in their naming? Let’s dive into the number of unique names given each year. Female names achieve peak creativity in 2007 with 20,568 unique names. Male creativity spikes a year later in 2008 with 14,615 unique names.

I was surprised that names have gotten less creative since 2007/2008. I thought that millennial would have gotten increasingly unique with the internet and access to highly-useful information like this blog post. Perhaps, instead, we’re getting stuck in an analysis paralysis, and people mostly just give up and pick whatever name is in the top 1000?

What else could explain this rise in both names? Perhaps the data got more accurate as it became easier to report names. Maybe names took off in the 1970’s because that’s when computers became popular and it became easier to record things.


  • Female names have far greater variety than male names.
  • Female names tend to fluctuate more in the upper-ranks.
  • Both male and female top names are holding a first-place rank for shorter duration than they have in the past.
  • Name creativity really started accelerating in the 1970’s, but peaked in 2008.
  • There’s a strong correlation between creativity in male names as in female names.
  • A name popular today will quickly decline in popularity later.

How did I do this analysis?

  • Step 1: The Social Security Administration reports all baby names each year in the United States, given the name occurs at least 5 times. I downloaded these easily from here. Then I combined them together into one dataset.
  • Step 2: Combine the data across years and plot using the code from here.

  1. It even breaks it down by state. It’ll return any name that is reported more than 5 times. So if the name “Juniper” is only given to four babies in the US in a given year, Juniper won’t appear in the database.

  2. To check this, I looked at the CDC’s reported population count for 2017 and matched it with the number of names I could find in the SSA’s database. Turns out the SSA database covers about 92% of all names in America. So it’s not 100% of the names.
