I’ve been waiting for the top boy and girls to repeat for a state, and at last they have – Tasmania shares its #1 boy and girl names with South Australia.

On the girls’ Top 10 20, Ruby continues to sparkle at #1, and in fact has increased her lead. In 2010, she was used eight more times than the #2 name; last year there were almost twice as many babies named Ruby as the next name down.

The name that increased the most in popularity was Ava, rising ten places from #13 to #3. Amelia and Olivia were not far behind, and Zoe and Sophie made modest rises.

The name falling the most was Mia, going down from #5 to #10; surprising when you think how well she did in other states. Other names decreasing in popularity were Ella, Isabella, Bella, Holly and Chloe.

Grace, Charlotte, Matilda, Emily, Lily, Isabelle and Evie were stable, and Lucy and Imogen didn’t change position.

New to the Top 20 were Stella, Layla, Lilly, Sophia, Hannah, Isla, Sienna, Phoebe and Ellie. Departed were Hayley, Molly, Georgia, Maddison and Paige.

On the boys’ Top 20, Oliver joined Ruby by remaining the #1 name for another year.

Henry went up the most, increasing his position nine places from #17 to #8. Also rising were Samuel, Ethan, Lucas and Xavier.

Tyler plummeted twelve places from #7 to #19, and Harry, Max, Lachlan, James, Charlie, Jack, Thomas and Riley also had significant losses.

Jacob, Cooper, Alexander, Angus, Archie and Oscar remained stable, while William, Noah and Connor didn’t change their position.

I based names’ position on their overall number of uses, as there were so many names sharing position. One of the anomalies of this system is that although there were no new names in the boys’ Top 20, it lost twenty-two names: Joshua, Liam, Logan, Benjamin, Isaac, Ryan, Bailey, Jackson, Mitchell, Hamish, Blake, Jordan, Sebastian, Hunter, Lincoln, Jake, Aiden, Jesse, Zachary, Harrison, Eli and Daniel.

A smaller population obviously leads to much greater volatility, and probably a few rather odd results.

Tasmania definitely has its own style of naming, with more cosy older-style names such as Olive, Esther, Eleanor, Florence, Elsie, Maggie and Meg on the full girls’ list, and a dizzying array of spelling variants. Incidentally, I note that Halle, which was a unique name in 2010, was used six times in 2011 – enough to get it onto the Top 100.

On the boys’ list, surname names seem more prevalent than usual, as well as Scottish and Irish names like Campbell and Rory, and short forms like Tom and Billy. Classic Robert can also be found on the Tasmanian Top 100. The number of babies named Flynn went from 9 to 15, putting it into the Top 100, while Tasmanians seemed immune to the charms of Harper and Savannah.
