A little boy born in 2026 has a good chance of having a short first name, loaded with religious symbolism and yet long under the radar. For decades, this name from the Old Testament lived far from the podiums, eclipsed by classics like Leo. Today, the statistical curves tell a completely different story.
The civil status files used by theINSEE
and projections of The Official Names
convergent: an ancient biblical first name, which remained discreet during the 20th century, is climbing at full speed. Analysts have observed an average increase of close to 15% per year since 2022 and see it entering the top 3 nationally in 2026. This surprise first name is Isaac.
Isaac, the discreet biblical first name that INSEE has seen come up
In the Bible, Isaac is the son of Abraham and Sarah, the unexpected child whose first name means “he will laugh” in Hebrew. For a long time, this strong reference toOld Testament remained a minority in France, far from the success of Gabriel or Raphaël, although they came from the same religious imagination; over the generations, it almost seemed like a niche choice.
The series of the civil status first name file, held by theINSEE since 1900, show that Isaac never disappeared but remained rare throughout the 20th century. Of just over 24,000 births recorded since 1900, nearly four out of ten occurred only in the 2010s, a sign of a real awakening.
A lightning rise: the first name Isaac towards the top 3 in 2026
Between 2019 and 2023, French maternity wards saw around 1,700 and then more than 2,500 little boys named
Isaacaccording to public data from the first name file. The curve climbs almost every year. Projections now speak of average growth close to
+15% per year since 2022, sufficient to aim for the men’s top 3 in 2026.
Name experts describe Isaac as the new ideal classic: a biblical first name solid, short, easy to pronounce everywhere, with an “ac” ending which contrasts with the soft sounds of Léo or Noah. A well-followed celebrity couple recently chose it for their son, which often acts as a dazzling fashion accelerator.
Real alternatives to the first name Isaas
For parents, the charm of Isaac also comes from the impression of choosing an original first name. In reality, with more than 2,500 births per year, the probability of meeting two or three Isaacs in the same kindergarten class is becoming very real, especially in large cities. To stay in the same style while avoiding the future top 10, certain cousin first names are slowly rising:
- Elijahgentler but just as biblical.
- Comochic and very short.
- Abela sober alternative to Gabriel and Raphaël.
The basis of theINSEE lists, year by year since 1900, first names that are sufficiently widespread, with at least twenty births over the period and three in the same year, the others being grouped under the label “rare first names”. Since 1993, parents have chosen freely, as long as the first name does not harm the child. Those who want to remain sheltered from fashion effects can look to Lazare or Barthimée, who are still very confidential.
