Origin
The surname Prokopiak is believed to have originated in Belarus and western Russia during the medieval period. It is derived from the Slavic personal name Prokop, which itself comes from the Greek name Prokopios meaning "progress" or "advancement." Variations of the spelling in historical records include Prokopyak, Prokopjak, and Prokopenko.
One of the earliest known references to the name Prokopiak can be found in a 16th century tax registry from the town of Orsha in modern-day Belarus. The document lists a certain Ivan Prokopiak as a landowner in the region. Another early mention is of a Grigory Prokopiak, a soldier in the Russian army during the reign of Tsar Alexis I in the mid-1600s.
In the 18th century, the name appears in church records from the village of Zhlobin, near the city of Gomel in eastern Belarus. A Yefim Prokopiak and his wife Aksiniya are listed as having several children baptized there between 1720 and 1740. Around the same time, a Semyon Prokopiak is recorded as a merchant in the town of Chernigov, which was then part of the Russian Empire.
One of the earliest known bearers of the Prokopiak name to gain prominence was Yegor Prokopiak, a Russian revolutionary born in 1869 in the village of Peresypkino. He was an active member of the Bolshevik party and participated in the 1917 Russian Revolution. After the establishment of the Soviet Union, Prokopiak served as a regional party leader in Siberia until his death in 1935.
Another notable figure was Andrei Prokopiak, a Belarusian painter born in 1890 in the town of Bobruisk. He was a leading artist of the Belarusian avant-garde movement in the early 20th century and is particularly known for his cubist-inspired landscapes and portraits. Prokopiak's works can be found in museums across Belarus and Russia.
Demographics
Among Census respondents with the surname Prokopiak, the largest self-reported group is White at 92.8%. The next largest groups are Hispanic (4.5%) and American Indian/Alaska Native (1.8%).
The bar chart below shows how Prokopiak 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 Prokopiak surname at the time of the 2020 Census, not any inherent property of the name itself.

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 Prokopiak (2000, 2010, 2020).
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.
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.
