I didn't really look at the popularity lists to decide if the names were popular or not, I don't care.
Do I like it, does it go with our surname, is it easy to pronounce, those are things that we considered.
Boy names are especially hard IME because there is less variety - the popular names are so overused, but the less popular ones are mostly just weird and don't sound like proper names. I think it's much easier to find a pretty girls' name which is not top ten but not something weird and made up either.
You tend to see trends in names because people will independently come across a name and each think "Oh that sounds nice - and unusual". But not realise that several other people have had the same thought. About ten years ago, I'd never come across the name Arlo. Now it's top 20. That's not necessarily because people are studying the name lists and picking from there, it's more likely because they have met a baby or toddler called Arlo and thought that's unusual, what a lovely name, and it's stuck with them and when they had a baby a couple of years later, it's made it onto their list.
You tend not to see many names which were a trend in your own generation (because people associate that with boring or ordinary = yet another dave etc) and not many names that were associated with the grandparents' generation, because to the parents, those are grown-up names, have no association with "cuteness" and look weird on a baby, like Kevin, Linda, Barry.
But great-grandparents' generation is fair game, mainly because most adults having children have already, perhaps recently, lost grandparents and those names are seen fondly, but they are already out of use enough that they are starting to seem a novelty again. For our generation I would say this is the Alfie, Elizabeth, May, Stanley, Agnes etc.
Weirdly I was really attached to the name Idris, DH vetoed it for being too unusual and I've just looked this up and it is a current name trend. It's gone from the the 5/6oos in the late 90s/early 2000s, certainly I'd never met one IRL, to now being in the top 200. Something must have inspired not just me, but also hundreds of other parents. I have fond memories of this name from childhood associated with a toy dragon that I had, which I think my mum named after a cartoon that was on TV at the time (Ivor the Engine) - I don't remember the cartoon, but other people my age would likely have had the same exposure. And then with Idris Elba being successful, that lends a kind of respect to the name, showing that it isn't just a cute character, it's also a serious adult name. I liked the association with Wales as well as my grandma was Welsh, but that's not something that would change generationally.
Tobias is another example of a name that I really liked and haven't met a lot of - this is also beginning to climb.
Something else to bear in mind is that the popular names today are still not as popular as they were in the past. If you look at Jack for example which was at number 1 in 1996, there were 10,779 Jacks born in that year, which represented about 3.2% of all boys. But the number 1 boys' name in 2021 was Noah and there were only 4,525 born (1.4% of boys). If you try to find the name that is about as popular in 1996 as Noah is today, it was Adam, which was 16th most popular. Sure, it is a very "normal" name (some might say boring) but I don't think I've known that many Adams. Maybe two? Whereas I can think of at least five Jacks that I've been at school with, friends' boyfriends, brothers etc.
In 1996, the top 10 boys' names represented 24% of all boys born that year, and the top 20 was 38%. Over half of boys had a name which was one of the top 33 names.
In 2021, the top 10 boys' names only represent 11% of all boys born that year. You don't even get to 24% until you get to rank 31 - I got bored and didn't keep going to find the 50% tipping point.
Girls' names are more varied, in 2021 and 1996, but the change to more name variation continues as well -
in 2021, 9% of girls had a name in the top ten, 15% top 20.
19% top ten in 1996, 31% top 20. The tipping point of 50% is top 60 names.
