Origin
Meaning and origin of Serdyuk
The surname Serdyuk originated in Ukraine and Russia during the 16th century. It is derived from the Ukrainian word "serdyty", meaning "to be angry" or "to be furious". This suggests that the name may have been given to someone with a fiery or irritable temperament.
In its earliest recorded forms, the name was spelled as "Serdyuk" or "Serdiouk". It is believed to have originated in the regions of Chernihiv and Poltava in modern-day Ukraine, as well as in parts of southern Russia.
One of the earliest recorded instances of the name can be found in a monastery record from the city of Novhorod-Siverskyi, dated 1587, which mentions a villager named Ivan Serdyuk. Another early reference is in a tax register from the town of Romny, in the Poltava region of Ukraine, from 1612, which lists a landowner named Hryhoriy Serdyuk.
During the 17th and 18th centuries, the name began to spread to other parts of the Russian Empire, including modern-day Belarus and the Kuban region of southern Russia. It is believed that some Serdyuks may have been Cossacks, as the name is found in Cossack registers from this period.
Notable individuals with the surname Serdyuk throughout history include:
1. Oleksandr Serdyuk (1900-1976), a Ukrainian poet and writer who was a prominent figure in the literary movement known as the "Executed Renaissance".
2. Hryhoriy Serdyuk (1830-1903), a Ukrainian artist and painter known for his landscapes and portraits of Ukrainian peasants.
3. Yevhen Serdyuk (1868-1937), a Ukrainian military officer who served in the Imperial Russian Army during World War I and later joined the Ukrainian People's Army during the Ukrainian War of Independence.
4. Yuriy Serdyuk (1935-2010), a Soviet and Ukrainian actor who appeared in numerous films and television shows, including the popular series "The Rich Also Cry".
5. Mariya Serdyuk (1876-1950), a Ukrainian folk singer and storyteller who helped preserve traditional Ukrainian oral culture and folklore.

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

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
