This site's popularity landing page used to display the top boy and girl name for each country. The page was recently redesigned to make it less cluttered, and this information was removed. I was sad to see it go however, so I created a new page that will display the top names for each country side-by-side:
https://www.behindthename.com/top/sidebyside
The controls allow you to compare different sets of lists. If you change the timespan to anything other than 1 year, then the page will compute the most popular names over that entire span (by summing up the number of bearers). Hopefully this is useful and/or fun!
