A focused population profile of German-American Illinois, with modern genetic matches, ancestry modeling, and a World Genetics G25 heatmap.
German-American Illinois is included in the World Genetics modern G25 database as a reference population. This page uses that reference average to compare German-American Illinois 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 German-American Illinois.
In the World Genetics modern G25 comparison, the closest non-self match for German-American Illinois is German Saxony. Other nearby references include German Saxony-Anhalt, German Thuringia, German Saxony Erzgebirgskreis, and German North Moravia. This gives the German-American Illinois profile its nearest modern genetic context inside the current reference database.

The ancestral breakdown below loads the best-fitting World Genetics calculator for the German-American Illinois 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 German-American Illinois profile a geographic shape. Warmer areas mark regions where available modern reference populations sit closer to the German-American Illinois average, while cooler areas represent more distant matches.
The closest non-self match in this World Genetics comparison is German Saxony. Other nearby references include German Saxony-Anhalt, German Thuringia, German Saxony Erzgebirgskreis, and German North Moravia.
In the current modern G25 reference set, German Saxony is the closest listed match to the German-American Illinois average after removing German-American Illinois itself from the table.
The heatmap shows where modern reference populations are closer or farther from the German-American Illinois G25 average, giving the closest-match results a geographic view.
