Meaning and origin of Kubiak
The surname Kubiak is of Polish origin, dating back to the Middle Ages. It is derived from the word "kub," which means a rounded container or bowl in Polish. The name likely originated from a maker or seller of such containers.
The earliest known recording of the Kubiak surname can be traced back to the 15th century in the region of Greater Poland. In 1412, a record mentions a certain Jakub Kubiak, a craftsman from the town of Poznań.
During the 16th and 17th centuries, the name appeared in various historical documents and records across Poland. In 1587, a document from the city of Krakow listed a merchant named Jan Kubiak. Another notable mention is from 1643, when a soldier named Michał Kubiak fought in the Polish-Swedish War.
One of the earliest recorded instances of the Kubiak name outside of Poland is from the late 18th century, when Polish immigrants began settling in various parts of Europe and North America. In 1789, a Polish settler named Stanisław Kubiak was recorded as one of the first residents of the town of Wilno, now known as Vilnius, Lithuania.
Throughout history, several notable individuals have borne the Kubiak surname. In the 19th century, Józef Kubiak (1810-1892) was a renowned Polish painter and art teacher. Another notable figure was Wacław Kubiak (1872-1947), a Polish engineer and inventor who pioneered the use of reinforced concrete in construction.
In the 20th century, Tadeusz Kubiak (1924-1979) was a celebrated Polish writer and poet, known for his works exploring the themes of war and human suffering. Mieczysław Kubiak (1912-1998) was a respected Polish economist and academic, who made significant contributions to the field of economic theory.

The bar chart below shows how Kubiak 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 Kubiak surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
