A focused population profile of the Welsh, their British and Atlantic background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
The Welsh are the people of Wales, with regional histories tied to north Wales, south Wales, Powys, Dyfed, Gwynedd, the Marches, and Welsh diaspora communities. Welsh population history is connected to ancient Brittonic-speaking populations, medieval Welsh kingdoms, borderland interaction with England, industrial-era migration, and modern bilingual national identity.
Welsh is a Celtic language and remains central to Welsh identity, while English is also widely spoken. Wales has strong regional variation between rural Welsh-speaking areas, industrial south Wales, coastal towns, and border communities.
As a genetic reference, Welsh should be read as a British Isles profile with close links to English, Cornish, Scottish, Irish, Breton, Dutch, and broader northwest European references.
In the World Genetics modern G25 comparison, the closest non-self match for Welsh is Anglo-Australian. Other nearby references include Anglo-Canadian Newfoundland and Labrador, Cornish, English, and Anglo-American Utah. This gives the Welsh profile its nearest modern genetic context inside the current reference database.

The ancestry breakdown gives deeper component proportions, while closest matches show modern similarity. Welsh is best interpreted as a British and Atlantic northwest European profile, with English, Cornish, Manx, Breton, and Dutch references nearby.
The heatmap should emphasize Wales, England, Cornwall, the Isle of Man, Brittany, the Netherlands, and nearby northwest European coastal references.
The closest non-self match in this World Genetics comparison is Anglo-Australian. Other nearby references include Anglo-Canadian Newfoundland and Labrador, Cornish, English, and Anglo-American Utah.
In the current modern G25 reference set, Anglo-Australian is the closest listed match to the Welsh average after removing Welsh itself from the table.
The heatmap shows where modern reference populations are closer or farther from the Welsh G25 average, giving the closest-match results a geographic view.
