I just think it's remarkable how little overlap there is now between England/Wales and the USA in the top names. There are only five male names (
Oliver,
Noah,
Henry,
Jacob, and
William) that are on both lists for 2020.
The use of diminutives ending in -ie as official forms for boys is a big difference between English and American culture. I think most Americans will be very surprised to see
Archie,
Charlie,
Freddie, and
Alfie in the top 20 in England.
Different sets of immigrants of course figure in to this, with
Muhammad in England vs.
Mateo in the USA showing how Muslims are a much bigger community in England and Hispanics much more important in the USA.
Lucas,
Alexander,
Michael,
Daniel, and
Sebastian also probably get some help from the Hispanic population in the USA in terms of the American top 20.
Theodore is booming in the USA and will surely be in our top 20 soon.
Theo and
Leo are also rising swiftly in
America.
Arthur is rising more slowly in the USA. It may possibly be the next
Henry here -- a name which is initially much more popular with college-educated parents and which slowly keeps rising for 25 years or so before it finally breaks into the top ten.
