Cool new interactive map shows how popular baby names are in every part of Wales – check out your area
A new interactive map shows you how popular the most common names are in every parts of Wales – based on the latest data from the Office of National Statistics.
Noah and Olivia kept their places as the most popular boys’ and girls’ baby names in Wales in 2021 – but that popularity wasn’t evenly distributed across the country.
Noah was the most or the join most popular name in 12 of Wales’ 22 local authorities, with Olivia in the top spot in eight.
But some local authorities had their own unique names in the top spot, such as Tomi in Ceredigion and Myles in Merthyr Tydfil.
Cadi was the most popular name in Gwynedd and, surprisingly, Delilah in Ceredigion. Perhaps they had been listening to a lot of Tom Jones.
All the data by the ONS including the interactive maps embedded below can be found here.

I don’t know what frustrates me more. The lack of Welsh baby names appearing on the list or Wales being lumped in with England when it comes to statistics. For heaven’s sake haven’t we got anyone here in Wales who can compile a list like in Scotland or are we going to be forever an English appendage? 🙄
