The Top Baby Name Drops, 1881 to Today

We looked at the top baby name rises last month, so this month let’s look at the opposite: the top drops. That is, the baby names that decreased the most in usage, percentage-wise, from one year to the next in the Social Security Administration’s data.

Here’s the format: girl names are on the left, boy names are on the right, and the percentages represent single-year slides in usage. (For example, from 1880 to 1881, usage of the girl name Clementine dropped 68% and usage of the boy name Neil dropped 76%.)

  • 1881: Clementine, -68%; Neil, -76%

The SSA data isn’t perfect, but it does become more accurate in the late 1930s, because “many people born before 1937 never applied for a Social Security card, so their names are not included in our data” (SSA). Now, back to the list…

(Did you catch the doubles? Alvie, Tatsuo, and Fae/Faye.)

Top drops aren’t quite as exciting as top rises, but certain ones become much more intriguing when you notice that they were also top rises:

  • Rose-then-dropped: Clarance, Lollie, Lindsay, Zudora, Tatsuo, Liberty, Norita, Vallorie, Krystal, Seneca, Nakia, Mikalah, Bethzy, Thaily
  • Dropped-then-rose: Clementine, Malissa, Diana, Alvie, Pierce, Judge, Rosendo

I’ve already written about some of the names above (click the links to see the posts) and I plan to write about a few of the others. In the meanwhile, though, feel free to beat me to it — leave a comment and let us know why you think any of these names saw dropped in usage when they did.

Most Popular First Letter-Pairs of U.S. Baby Names

Mathematically speaking, it’s possible to construct 676 pairs of letters from a 26-letter alphabet. In terms of baby names, though, only a portion of these pairs can realistically be used to start a baby name.

If you look at each of the 6,692 names that have ever ranked among the most popular U.S. (1880-2006), you’ll notice that only 233 two-letter combinations have ever been used at the beginning of the names (e.g., “Na-” for Nancy, or “Ev-” for Evan).

So…what’s the most common pair of starting letters?

Ma– is the clear winner. It starts nearly twice as many names as Ja-, the second most common starting letter-pair.

Here’s a more detailed breakdown of all the two-letter combinations that have started at least 100 ranked baby names:

  • 331 “Ma-” names (Mark, Mandy, Matthias, Marylouise)
  • 177 “Ja-” names (Jane, Jacob, Jaleesa, Jamarion)
  • 174 “Al-” names (Alf, Alice, Alphonso, Albertina)
  • 167 “De-” names (Dean, Della, Devontae, Demetria)
  • 157 “Ka-” names (Karl, Katie, Kameron, Katharina)
  • 144 “Sh-” names (Shane, Sherman, Shanice, Sheridan)
  • 143 “Ca-” names (Cash, Cadence, Carmella, Casimiro)
  • 139 “Da-” names (Dave, Daisy, Damarcus, Dayanara)
  • 125 “El-” names (Elmo, Elyse, Elijah, Eleanora)
  • 121 “Ro-” names (Ross, Roxie, Roosevelt, Rosalinda)
  • 118 “Br-” names (Bruce, Brenda, Bryson, Brittany)
  • 118 “Ch-” names (Chad, Chantal, Christopher, Christiana)
  • 117 “La-” names (Lane, Laura, Lafayette, Lakeshia)
  • 113 “Le-” names (Les, Leah, Leandra, Leopoldo)
  • 102 “Je-” names (Jeff, Jewel, Jennifer, Jeremiah)
  • 101 “Jo-” names (John, Joanna, Joshua, Josefina)
  • 100 “Ar-” names (Art, Arla, Armani, Araceli)

One-hit wonder baby names (in the top 1,000)

Not one-hit wonder pop songs, but one-hit wonder baby names!

Many baby names have only managed to rank among the most popular in the U.S. a single time.

Here are all the one-hit wonders of the top 1,000 so far (1880-2005), grouped by decade. If I’ve written an explanatory post about the name, I’ve added a link to the post.

(Please note that the rankings from earliest decades are based on data that isn’t very reliable. So, most of those names didn’t make the top 1,000 for any particular reason — they’re mostly just statistical anomalies.)
