Origin
The surname STEPANYUK originated in Ukraine and dates back to the 16th century. It is derived from the Ukrainian word "step", meaning "steppe" or "grassland", and the suffix "-yuk" which was commonly used to form patronymic surnames in the region. This suggests that the name may have initially referred to someone who lived or worked on the steppes of Ukraine.
One of the earliest recorded references to this surname can be found in the Cossack Registry of 1649, where a certain Hryhoriy Stepanyuk is listed as a member of the Cossack forces. The Cossacks were a semi-military group that played a significant role in the history of Ukraine, and many of their members took on surnames that reflected their way of life or geographic origins.
In the 18th century, the name appears in various church records and land registries in the regions of Poltava and Chernihiv, which were part of the Cossack Hetmanate at the time. This suggests that the Stepanyuk family may have had connections to the Cossack communities in these areas.
One notable figure bearing this surname was Mykola Stepanyuk (1857-1921), a Ukrainian writer and journalist who was active in the literary circles of Kyiv in the late 19th and early 20th centuries. He published several works of fiction and poetry that explored themes of Ukrainian identity and national culture.
Another individual of historical significance was Hryhoriy Stepanyuk (1884-1937), a Ukrainian political activist and member of the Central Council of Ukraine during the revolutionary period of 1917-1920. He was arrested and executed during the Stalinist purges of the 1930s.
In the early 20th century, a small number of individuals with the surname Stepanyuk emigrated from Ukraine to other parts of the world, including Canada and the United States. One such person was Pavlo Stepanyuk (1895-1968), who settled in Winnipeg, Canada, and became involved in the Ukrainian diaspora community there.
While the surname STEPANYUK is not among the most common in Ukraine today, it continues to be associated with the country's rich cultural heritage and the historical legacy of the Cossack communities that once thrived in the region.
Demographics
Among Census respondents with the surname Stepanyuk, the largest self-reported group is White at 96.4%. The next largest groups are Black (1.2%) and Asian/Pacific Islander (1.2%).
The bar chart below shows how Stepanyuk 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 Stepanyuk surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
