I’ve never posted rankings for Peterborough before, but research reveals that the city’s top names of 2018 were Olivia and Mohammad. In fact, “Mohammad” (which includes Mohammed, Muhammad, and all other spellings) had been the #1 boy name “[f]or the 11th year in a row” at that point.

Here are the most recent rankings for England and Wales (2023), as well as a recent-ish sent set of rankings for the English county of Oxfordshire (located 60 miles north-west of London).

Australia overall

Using the data above, let’s make a guess about Australia’s top baby names overall.

Here’s what I came up with:

Possible top girl names (Australia, 2023)Possible top boy names (Australia, 2023)
1. Isla
2. Amelia
3. Charlotte
4. Olivia
5. Mia		1. Oliver
2. Noah
3. Henry
4. Leo
5. Theodore

What are your thoughts on these? (Which names would you have put at the top?)

P.S. I guessed that Charlotte and Oliver were the #1 names in the country in 2022…
