Common ground at the top
The lists diverge substantially overall, but a few names at the top have achieved transatlantic consensus. Olivia and Noah hold the same exceptionally high position in both countries, while Amelia, Isabella, Oliver and Theodore reach both top 10s.
The #1 boy names, however, are notably different: Liam in the US is #63 in the UK, while the UK's Muhammad doesn't make the US top 100 at all.
Short and sweet vs. tried and true
We find many more short, sweet, nickname-like names on the UK side, especially for boys. Freddie, Archie, Alfie, Charlie and Teddy appear alongside Rosie, Lottie, Evie and Bonnie.
Shared favorites such as Theo, Emma and Ellie show that short, sweet names appeal in both countries, but the UK embraces the style much more fully.
The American rankings, on the other hand, draw more deeply from classic biblical and long-established names. John, Matthew, Luke and Anthony join Naomi, Victoria, Claire and Sarah.
But there is a bit more overlap in this category, where both countries rank traditional staples such as Theodore, James, William, Charlotte and Elizabeth.
Ancient names, modern comebacks
The US list also favors a newer wave of ancient biblical names that only gained real traction in recent decades, giving them a more modern feel despite their centuries of history. Levi, Asher, Ezra, Josiah, Ezekiel, Silas, Adriel and Micah all rank in the American top 100 for boys.
Some of these revivals are shared favorites, including Noah, Elijah, Isaac, Caleb and Ezra, and Delilah and Eden for girls.
Global names, different roots
Both countries’ rankings reflect a wide range of cultural influences, but their differences reflect different cultural ties and communities.
The US list has a stronger Spanish-language and southern European presence, with boys’ names such as Mateo, Santiago, Thiago, Jose, Leonardo and Emiliano, alongside Camila, Gianna, Valentina and Lucia for girls.
Rugged Americana
The US list has a handful of boys’ names drawing on a distinctively rugged, Western influence. Maverick, Wyatt, Weston, Waylon, Brooks, Beau, Lincoln, Walker and Archer all rank in the American top 100 but not in the UK.
Britain has a few unexpected outliers of its own, though: Hunter, Austin and Cody all appear in the UK top 100 while missing the American list.
Last names, first choices
Names that have historically been surnames are popular in both countries, especially for boys. Hudson, Mason, Carter, Grayson and Cooper appear in both top 100s, while the US adds Jackson, Bennett and Brooks, and the UK favors Harrison, Finley and Ellis.
The bigger divide is among girls. Harper charts in both countries, but names like Avery, Madison, Paisley, Addison, Kennedy, Kinsley and Quinn appear only in the US top 100.
Vintage revivals, two flavors
Both countries are looking to the past, reviving vintage favorites such as Theodore, Arthur, Jack, Evelyn, Violet, Hazel, Ruby, Alice and Clara. Beyond those common choices, however, their vintage tastes begin to split.
Britain leans toward names with a quaint, distinctly old-fashioned character: George, Oscar, Frederick, Albert and Rupert for boys, and Florence, Mabel, Matilda, Ada, Harriet and Ottilie for girls.
Nature in common
Nature names are one of the places with the most overlap, especially among girls’ names. Lily, Violet, Ivy, Hazel, Willow, Iris and Daisy appear in both countries’ top 100s, alongside celestial and landscape-inspired choices such as Aurora, Luna, Nova, Eden and Isla.
Britain also favors traditional botanical names such as Poppy, Olive, Rose and Rosa, while the US ranges a bit more widely with Autumn, Jade, Juniper and Leilani.

The two lists, side by side
The two lists line up in only two places at the very top: Olivia is the #1 girl name in both countries, and Noah is the #2 boy name in both.
Most of the other shared names rank very differently. For example, Emma ranks #3 in the US but only #84 in the UK, and Arthur is #6 in the UK against #87 in the US.
