Origin
The surname WILK originates from Poland, where it first appeared in the early 13th century. It is derived from the Polish word "wilk," meaning "wolf." This suggests that the name may have initially referred to someone who lived near a wooded area inhabited by wolves or someone with wolf-like characteristics.
One of the earliest recorded instances of the WILK surname can be found in the "Liber Beneficiorum" (Book of Benefices) from the Archdiocese of Gniezno, dated around 1275. This medieval document mentions a cleric named "Wilk de Dobramila" from the village of Dobramila.
In the 14th century, the surname WILK appeared in various historical records across different regions of Poland. For instance, in 1388, a landowner named "Janek Wilk" was mentioned in a document from the town of Kraków.
The WILK surname has also been associated with several notable individuals throughout history. One example is Stanisław WILK (1516-1598), a Polish nobleman and military commander who fought in the Livonian War against Russia. Another is Józef WILK (1800-1854), a Polish poet and translator known for his translations of works by Lord Byron and Adam Mickiewicz.
In the 16th century, the variant spelling "WILCZ" emerged, likely due to the influence of the Polish word "wilczy," meaning "of the wolf." This spelling can be found in records from the town of Sandomierz, where a merchant named "Maciej Wilcz" is mentioned in 1543.
The WILK surname has also been connected to various place names in Poland, such as the village of Wilków near Radom, and the town of Wilkowice in the Silesian region, both of which may have derived their names from the presence of wolves or from individuals bearing the WILK surname.
Other notable individuals with the WILK surname include Andrzej WILK (1870-1929), a Polish painter and illustrator known for his landscapes and portraits, and Eugeniusz WILK (1916-1997), a Polish engineer and inventor who developed several innovative technologies for the mining industry.
Demographics
Among Census respondents with the surname Wilk, the largest self-reported group is White at 93.5%. The next largest groups are Hispanic (2.9%) and Two or More Races (2.2%).
The bar chart below shows how Wilk 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 Wilk 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.
