A focused population profile of Northern Irish, with modern genetic matches, ancestry modeling, and a World Genetics G25 heatmap.
Northern Irish is included in the World Genetics modern G25 database as a reference population. This page uses that reference average to compare Northern Irish with other modern populations in the database.
The label should be read as a population reference name rather than a complete description of every individual, family, language, region, or community history connected with Northern Irish.
In the World Genetics modern G25 comparison, the closest non-self match for Northern Irish is Dutch Central. Other nearby references include Dutch South Holland, Dutch Gelderland, Orcadian, and Scottish. This gives the Northern Irish profile its nearest modern genetic context inside the current reference database.

The ancestral breakdown below loads the best-fitting World Genetics calculator for the Northern Irish average. It should be read as a model of deep ancestry components, while the closest-match table is the better guide to which modern populations are most similar in G25 space.
The heatmap gives the Northern Irish profile a geographic shape. Warmer areas mark regions where available modern reference populations sit closer to the Northern Irish average, while cooler areas represent more distant matches.
The closest non-self match in this World Genetics comparison is Dutch Central. Other nearby references include Dutch South Holland, Dutch Gelderland, Orcadian, and Scottish.
In the current modern G25 reference set, Dutch Central is the closest listed match to the Northern Irish average after removing Northern Irish itself from the table.
The heatmap shows where modern reference populations are closer or farther from the Northern Irish G25 average, giving the closest-match results a geographic view.
