The most popular boy's name and the most popular girl's name for babies born in Utah last year are two sides of the same coin — again.

According to the Social Security Administration, Oliver was No. 1 for boys; Olivia was No. 1 for girls. And 2018 marked the third year in a row that Oliver and Olivia topped the Utah list.

They were both No. 2 in the state the year before that.

(That's based on requests for Social Security numbers for newborns.)

Both names are also popular nationally, just not quite as popular. Oliver was No. 5 in the United States in 2018; Olivia was No. 2.

The most popular baby names in 2018, both in Utah and nationally, were:
