I don’t believe popularity is important whatsoever, and that it’s highly unlikely for a child to be one of more than 3 in one class with any given name, and here’s why;
Here are the number of births for each #1 name from 1980-1989
1980 - [name_f]Jennifer[/name_f] - 58,379 births
1981 - [name_f]Jennifer[/name_f] - 57,046 births
1982 - [name_f]Jennifer[/name_f] - 57,113 births
1983 - [name_f]Jennifer[/name_f] - 54,339 births
1984 - [name_f]Jennifer[/name_f] - 50,562 births
1985 - [name_f]Jessica[/name_f] - 48,345 births
1986 - [name_f]Jessica[/name_f] - 52,668 births
1987 - [name_f]Jessica[/name_f] - 55,988 births
1988 - [name_f]Jessica[/name_f] - 51,537 births
1989 - [name_f]Jessica[/name_f] - 47,882 births
Compared to the past decade;
2006 - [name_f]Emily[/name_f] - 21,398 births
2007 - [name_f]Emily[/name_f] - 19,535 births
2008 - [name_f]Emma[/name_f] - 18,806 births
2009 - [name_f]Isabella[/name_f] - 22,289 births
2010 - [name_f]Isabella[/name_f] - 22,898 births
2011 - [name_f]Sophia[/name_f] - 21,833 births
2012 - [name_f]Sophia[/name_f] - 22,292 births
2013 - [name_f]Sophia[/name_f] - 21,293 births
2014 - [name_f]Emma[/name_f] - 20,292 births
2015 - [name_f]Emma[/name_f] - 20,415 births
2016 - [name_f]Emma[/name_f] - 19,414 births
The difference in the trend is that so many less babies are being given that #1 name, it’s almost incomparable.
To put it into perspective, the names in the 1980s that sat between 18,000 and 23,000 births were in the lower end of the top 10, or even just outside the top 10.
Nowhere near as many babies are being given names within the top 100 as they once were. In 1980, 3.27% of all baby girls born that year were given #1 name [name_f]Jennifer[/name_f], vs. [name_f]Emma[/name_f]'s 1.01% in 2016.
To put it in perspective, the name in 1980 closest to 1.01% of all births was [name_f]Angela[/name_f], which was #12 that year.
Also, a lot of the time, names that don’t rank overly high in the national top 100, (or that don’t rank nationally in the top 100 at all) rank within a state’s top 100. So national popularity isn’t always a good indication.
For example: I went to school with 6 girls named [name_f]Kaitlyn[/name_f]. Nationally, though, the name was only #42.
I knew very few girls with names in the top 10 for the year we were born as well (I didn’t go to school with a single [name_u]Ashley[/name_u] (#2) or [name_u]Taylor[/name_u] (#6), and I never knew more than 2 girls with the names [name_f]Jessica[/name_f], [name_f]Brittany[/name_f], [name_f]Amanda[/name_f], [name_f]Emily[/name_f], [name_f]Samantha[/name_f] or [name_f]Hannah[/name_f] - in fact the only names I knew a multitude of girls with that ranked in the top 10 when I was born were [name_f]Sarah[/name_f] and [name_f]Elizabeth[/name_f]).
In short, no, popularity doesn’t bother me at all. Neither does trendiness or how dated a name feels.
It seems a bit silly to say “well I went to school with 6 Kaitlyns so I can’t use a top 10 name!!” when really, [name_f]Kaitlyn[/name_f] was well below the top 10 when I was born, or to say “I was one of 4 [name_f]Sarah[/name_f]'s - my daughter can’t be named [name_f]Emma[/name_f]!!!” when statistically, names aren’t shown to be as popular overall as they once were.
That’s just my take on it. I posted a similar response with top 10 data from 1986 vs. top 10 data from 2016 to this on another thread: Nameberry - Welcome to the Nameberry Forums
