It is the undisputed champion when it comes to names for baby boys in Scotland.
Jack has once again topped the list as the most popular choice for male newborns this year.
That marks an incredible decade as number one north of the Border.
The name’s modern dominance puts it on a par with historically popular names such as David, which was the leading choice for boys from 1980-89.
Olivia was the most popular choice for baby girls in 2017 for the second year in succession, an annual report from the National Records for Scotland (NRS) revealed.
Emily claimed the runner-up position.
But there was much more variety across the annual top 100 list of names.
Among the top first forenames for boys, Oliver climbed to second, while James was down to third.
A non-mover, Lewis remained in fourth place.
Noah and Logan were fifth and sixth, Harris rose six places to seventh, and Alexander and Leo remained in eighth and ninth positions.
Harry, however, fell three places to tenth.
As for the most popular names for girls, Isla rose one place to third and Sophie dropped one place to fourth.
Jessica rose two places to fifth, while Amelia remained sixth. Ava fell two places to seventh, and Ella remained in eighth.
NRS registered the births of 25,384 boys and 23,935 girls in the period covered by these figures.
Parents chose 3314 different first forenames for boys and 4221 different first forenames for girls.
In total, that means some 2063 boys and 2767 girls were given first forenames that were unique.
The numbers of different names, and of unique names, were well above the levels of ten, 20 or 40 years ago reflecting perhaps changes in society and its make up.
The number of boys with unique first forenames was greater this year (2063 in the period covered by these figures) than in the whole of 2007 (1797 names), 1997 (1126 names) or 1977 (761 names).
The NRS report notes, though, that many “unique” names are achieved simply by the significant varieties in spelling.
It also adds that if Calum and Callum were considered one name, then it would rise to 21st in the list of boys’ names.
The difference in spelling splits their number.
The Scottish Government’s Culture Secretary Fiona Hyslop said she thought the trends proved parents thought carefully over what names would best suit their offspring.
She said: “Naming your baby is such an important decision and it’s always fun to see the names parents around Scotland are choosing.”
And she added: “This year’s figures show some names have an enduring appeal, with Jack and Olivia confirming themselves as the most popular across Scotland – Jack for the tenth year in a row and Olivia for the second.
“The trend for unique names remains far higher than it has been in previous decades, indicating that today’s parents are thinking long and hard before choosing names for their babies.”
