Popular baby names in Australia, 2022

Flag of Australia
Flag of Australia

In 2022, Australia — which boasts a large number of endemic animals (e.g., koala, kangaroo, wallaby, wombat, dingo) — welcomed 300,684 human babies: 146,403 girls and 154,281 boys.

What were the most popular names among Australia’s newborns last year?

Well…we don’t know for sure. Because Australia doesn’t release baby name rankings that cover the entire country.

So let’s take a look at eight sets of regional Australian rankings — representing Australia’s six states and two most populous territories — and make a guess about the country’s top names overall.

Here are the rankings, ordered by total number of births per region (highest to lowest):

Australia overall

Finally, using the data above, let’s make a guess about Australia’s top baby names overall. Here’s what I came up with:

Australia’s top girl names (possibly)Australia’s top boy names (possibly)
1. Charlotte
2. Amelia
3. Isla
4. Olivia
5. Mia
1. Oliver
2. Noah
3. Leo
4. Henry
5. William

What are your thoughts on these? Would you have ranked them differently?

(My guesses regarding Australia’s top names of 2021 had Isla and Oliver in the top spots.)

Popular and unique baby names in Iowa, 2022

Flag of Iowa
Flag of Iowa

Did you know that Iowa is the only U.S. state bordered by two navigable rivers (i.e., rivers used for interstate commerce)? Its eastern border is formed by the Mississippi River, and its western border is formed by the Missouri River (for the most part).

Last year, the state’s most popular baby names were Olivia and Oliver, according to the Iowa Department of Health and Human Services

Here are Iowa’s top 20 girl names and top 20+ boy names of 2022:

The SSA’s rankings for Iowa are largely (though not exactly) the same.

Now for the fun part — unique names!

In total, 3,680 (67%) of the girl names and 2,801 (58%) of the boy names bestowed in Iowa last year were given to a single baby. Here’s a selection of Iowa’s unique baby names of 2022:

Unique girl namesUnique boy names
Alini, Brillith, Clovianna, Demri, Eleen, Fienne, Giantra, Hinata, Idara, Jimmilah, Ketsia, Lithena, Meridia, Nashley, Prinsha, Quinlyn, Rencalina, Simrat, Tauren, Uniti, Velzy, Weaver, Xella, Yusali, ZevlynAckley, Berrick, Clandson, Dazin, Eitan, Faron, Grayler, Hemby, Indie, Jefrin, Kindness, Lijah, Maiti, Noriel, Olten, Percy, Quineal, Raul, Solanus, Trendale, Ukiyo, Vaylor, Westlan, Xanthos, Yannick, Zario

Some of the single-use noun-names I spotted were Fjord (boy), Badger (boy), Minnow (girl), Sparrow (girl), Lithium (boy), and Paprika (girl).

I also noticed the name Caladan (boy), which was likely inspired by the planet Caladan from the movie Dune: Part One, which was released in late 2021.

Speaking of 2021…here’s a link to Iowa’s 2021 rankings, if you’d like to compare last year to the year before.
