A focused population profile of Polish-American Illinois, with modern genetic matches, ancestry modeling, and a World Genetics G25 heatmap.
Polish-American Illinois is included in the World Genetics modern G25 database as a reference population. This page uses that reference average to compare Polish-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 Polish-American Illinois.
In the World Genetics modern G25 comparison, the closest non-self match for Polish-American Illinois is Polish Kuyavia-Pomerania Bydgoszcz. Other nearby references include Polish Pomerania Gdansk, Polish, Polish Pomerania Sztum, and Polish Wielkopolska. This gives the Polish-American Illinois profile its nearest modern genetic context inside the current reference database.
