Origin
Meaning and origin of Jozwiak
The surname Jozwiak is of Polish origin, tracing its roots back to the 15th century. It is derived from the Polish personal name Jozwiak, a diminutive form of the name Józef (Joseph). The name is believed to have originated in the regions of Wielkopolska and Kujawsko-Pomorskie in west-central Poland.
One of the earliest recorded instances of the name Jozwiak can be found in the parish records of the village of Kcynia, located in the Kuyavian-Pomeranian Voivodeship, dating back to the late 16th century. These records mention a Marcin Jozwiak, who was born in 1578.
During the 17th century, the name Jozwiak appeared in various historical documents and records across Poland. In 1624, a Mikołaj Jozwiak was mentioned in the tax registers of the town of Pyzdry, located in the Greater Poland Voivodeship.
The Jozwiak name has also been associated with several notable individuals throughout history. One such figure was Jan Jozwiak, a Polish military commander who served during the Kościuszko Uprising against Imperial Russia and Prussia in 1794. He was born in 1758 and played a significant role in the defense of Warsaw before being captured and later executed by the Russians.
Another prominent individual with the Jozwiak surname was Franciszek Jozwiak, a Polish painter and artist who lived in the late 19th and early 20th centuries. He was born in 1859 in the town of Śrem, now part of the Greater Poland Voivodeship, and is known for his landscape and genre paintings.
In the 20th century, Bronisław Jozwiak, a Polish politician and member of the Sejm (parliament), made a significant impact. Born in 1902 in the village of Sławno, he served as a member of the Sejm from 1947 to 1952 and played a role in shaping post-war Poland.
The name Jozwiak has also been linked to various place names in Poland, such as the village of Jozwiaki in the Kuyavian-Pomeranian Voivodeship and the settlement of Jozwiakówka in the Lublin Voivodeship. These place names likely derived from the presence of families bearing the Jozwiak surname in those areas.
While the Jozwiak surname is primarily associated with Poland, it has also been adopted by individuals of Polish descent in other parts of the world, particularly in countries with significant Polish immigrant communities, such as the United States, Canada, and Australia.

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 Jozwiak surname at the time of the 2020 Census, not any inherent property of the name itself.

Is this page using the latest Census data?
Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Jozwiak (2000, 2010, 2020).
Does the Census include every surname?
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
