In a list of popular names closely mirroring those released last week by neighbouring New South Wales, traditional names continue to dominate.

Chloe rocketed to the top of the most popular girls' names after sitting in the No.6 spot for the past three years, with Ava appearing for the first time - in recent history at least - at No.2.

The ever-popular Sophie was this year joined on the list by Sophia, and Olivia reappeared at No.4 after a conspicuous absence in 2012, the year after it topped the list.

Alexander made its return to the boys' top 10 after a two-year absence, and along with Lucas they bumped out Ethan and Henry from the top 10.

Alexander Caldow, of Casey, was just one of the Alexanders born in 2013.

''We didn't know any other Alexanders but we've since met quite a few now through various mothers' groups and things,'' mum Melissa Caldow said.

Her great-grandfather was named Alexander, but there was more to

the name choice than just family history.

''My husband and I both have long sort of formal names, I'm Melissa and he's Matthew but we can shorten to Mel and Matt, so we quite like names like that; Alexander can be shortened to Alex,'' she said.

''They seem to be more of our generation's names coming back in … as we're now having babies; we have a few friends called Alex,'' she said.

''I think it's just that cycle of them all coming back.''

At the other end of the spectrum, there were 1839 deaths registered in 2013, according to the ACT Office of Regulatory Services, which records births, deaths and marriages.

The office has also logged 1385 marriages, plus 31 same-sex marriages in the five-day window that they were legal in the territory.

While those marriages have since been rendered invalid by a High Court ruling on the ACT legislation, they accounted for more than 2 per cent of the territory's weddings for the year.
