This is the first time I’ve seen the geometry term “tesseract” used as a baby name. As Wikipedia puts it, “the tesseract is to the cube as the cube is to the square.” It’s a hypercube, basically. The word was coined in the 1880s from the Greek words tessera, “four,” and aktis, “ray.” Definitely an unusual name…though it does conveniently shorten to Tess.

Biggest Changes, Baby Boy Names, 2017

Which boy names increased the most in popularity from 2016 to 2017? And which ones decreased the most?

There are a few different ways to answer this question. The SSA, for instance, likes to look at ranking differences within the top 1,000. And I like to augment their list by looking at raw number differences across all the data.

So let’s look at increases first…

Boy Names: Biggest Increases, 2016 to 2017

Rankings

1. Wells, +504 spots
2. Kairo, +423
3. Caspian, +328
4. Nova, +323
5. Colson, +323
6. Kace, +315
7. Kashton, +302
8. Koa, +294
9. Gatlin, +282
10. Bjorn, +276

Wells was influenced by Wells Adams, a contestant from The Bachelorette. Nova may have been influenced by “all those Villanova Wildcats basketball fans naming their sons in celebration of the 2016 NCAA Men’s Basketball Champions.”

Raw Numbers

1. Logan, +2,748 babies
2. Maverick, +1,751
3. Ezekiel, +1,350
4. Mateo, +1,181
5. Lincoln, +1,032
6. Theodore, +1,018
7. Matias, +643
8. Leo, +642
9. Jameson, +639
10. Rowan, +637

Other names that saw raw number increases in the 300+ range included Asher, Santiago, Ezra, Rhett, Waylon, and Legend.

And now let’s check out decreases…

Boy Names: Biggest Decreases, 2016 to 2017

Rankings

1. Riaan, -421 spots
2. Kylo, -245
3. Kolby, -195
4. Urijah, -189
5. Kamdyn, -189
6. Jamar, -163
7. Giovani, -160
8. Nickolas, -155
9. Chad, -155
10. Jair, -147

The higher they climb, the harder they fall: Riaan was the fastest-rising boy name of 2015, and Kylo was the fastest-rising boy name of 2016, and now they’re both plummeting in 2017.

Raw Numbers

1. Mason, -1,728 babies
2. Michael, -1,478
3. Ethan, -1,417
4. Jacob, -1,373
5. Daniel, -1,281
6. Andrew, -1,161
7. Gabriel, -1,124
8. Anthony, -1,049
9. Matthew, -994
10. Owen, -970

Other names that saw raw number drops in the (negative) 300+ range included Aiden, Jackson, Gavin, Ryder, Jase, Hudson, and Tristan.
