Kobe was influenced by the untimely death of basketball great Kobe Bryant (whose daughter, Gianna, had an equally strong influence on girl names.)

Theodore and Luka were also among the fastest risers of 2019.

The boy names that saw the largest increases in usage in terms of relative numbers of babies were…

  1. Omere, increased by 460%
  2. Ripp, 342%

  4. Vardaan, 280%
  5. Rip, 260%

  7. Sharvil, 255%
  8. Evian, 253%
  9. Neizan, 243%
  10. Barkon, 240%

Omere could be from Omere Harris, son of YouTubers (and former Love & Hip Hop-ers) Mendeecees Harris and Yandy Smith.

Ripp was a debut name just one year earlier. Speaking of debuts…

Here are the boy names that debuted most impressively in the 2020 data:

  1. Aarnik, debuted with 14 baby boys
  2. Itzan, 14
  3. Azhir, 13
  4. Carin, 13

  7. Amavi, 12 (a double-debut with 30 girls as well)
  8. Deluka, 12
  9. Ezrin, 12
  10. Hardyn, 12

Some explanations…

  • Itzan is probably from Spanish actor Itzan Escamilla, who stars in the Netflix series Élite.
  • Carin could be from Mexican singer Carin Leon (whose real name is Oscar; “Carin” is a shortening of his nickname, Oscarin.)
  • Jahkor was the name of a character in the Netflix movie All Day and a Night (2020).

The boy names that saw the largest decreases in usage in terms of absolute numbers of babies were…

  1. Ethan, decreased by 1,801 babies

  4. Mason, -1,407
  5. Matthew, -1,170
  6. Lucas, -1,164
  7. Carter, -1,141
  8. Jaxon, -1,132
  9. Isaac, -1,121
  10. Alexander, -1,113

The boy name that saw the largest decrease in usage in terms of relative numbers of babies was Daer (-80%), and the boy name that saw the steepest drop off the list was Montae (from 20 babies in 2019 to fewer than 5 in 2020).

Popular baby names in Northern Territory (Australia), 2020

According to the government of Northern Territory, Australia, the most popular baby names in NT in 2020 were Charlotte and William.

Here are Northern Territory’s top 10 girl names and top 10+ boy names of 2020:

Girl Names

  1. Charlotte, 15 baby girls
  2. Olivia, 14
  3. Isla, 12 (tie)
  4. Matilda, 12 (tie)
  5. Amelia, 10 (5-way tie)
  6. Grace, 10 (5-way tie)
  7. Hazel, 10 (5-way tie)
  8. Mia, 10 (5-way tie)
  9. Willow, 10 (5-way tie)
  10. Violet, 9

Boy Names

  1. William, 20 baby boys
  2. Jack, 16
  3. Oliver, 15
  4. Lucas, 14
  5. Alexander, 12
  6. Henry, 11 (3-way tie)
  7. James, 11 (3-way tie)
  8. Noah, 11 (3-way tie)
  9. Hudson, 10 (3-way tie)
  10. Isaac, 10 (3-way tie)
  11. Thomas, 10 (3-way tie)

On the boys’ side, Thomas is followed by an 8-way tie involving two names I don’t usually see in the rankings: Billy and Mayson. Mayson is especially interesting because the more traditional spelling, Mason, hasn’t made the list for the last two years (after ranking as high as 2nd in 2017).

In 2019, the top two names in NT were Grace and Oliver.
