In more recent history, the surname appears in the 18th century with figures like Tomasz Woznak, born in 1765, who was a notable member of the Polish-Lithuanian Commonwealth parliament. His involvement in politics and debates for the reform of the Commonwealth made him a recognized name in historical documents.
The 19th century also saw figures such as Wojciech Woznak, born in 1833, who gained prominence as an inventor and industrialist during the early stages of Poland's industrialization. His contributions to mechanical engineering and the establishment of factories in Warsaw are documented in numerous patents and economic records.

Demographics

The bar chart below shows how Woznak bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Woznak surname at the time of the 2020 Census, not any inherent property of the name itself.
