For the second year in a row, the most popular baby names in Utah were male-female versions of the same moniker — which bucked the 2017 national trends a bit.

It’s not Joseph and Josephine. Not Robert and Roberta. And not Max and Maxine.

New parents in the Beehive State lifted Oliver and Olivia to the top of the Utah list, just as they did in 2016, according to the Social Security Administration.

That means in just a few years Utah teachers will have to differentiate between multiple Olivers and Olivias in kindergarten classes across the state — Oliver vs. Ollie? Olivia vs. Livie?

The No. 1 names nationally — Liam and Emma — came in second in Utah.

The popularity of Oliver in Utah goes somewhat against the national numbers. Oliver was up to ninth nationally in 2017 — having risen steadily from 305th in 2000. Olivia was second nationally for the fourth year in a row, and it has been in the top 10 every year since 2001.

There are already a lot of Olivias in the nation’s classrooms, and there are going to be a lot more.

Why are the names so popular in Utah? Who knows? There aren’t a whole lot of famous Olivers out there, Goldie Hawn’s son Oliver Hudson (star of the sitcoms “Breaking Up Together” and “Rules of Engagement”) notwithstanding.

There are several famous Olivias — Munn, Wilde, Newton-John — but nobody who’s been big news in popular culture of late.

Neither name has been No. 1 nationally in past 118 year. (Social Security shares records that go back to 1900.)

Utah’s top four boys’ names in 2017 were a repeat from 2016 (Oliver, Liam, William and James, in that order), with Benjamin replacing Henry at No. 5. The top four girls’ names, in order, were a repeat from 2016; Hazel replaced Harper at No. 5.
