Origin
The surname Prock originates from the German-speaking regions of Europe, particularly in Austria and parts of southern Germany. Its earliest recorded use dates back to the 16th century, where it was likely derived from the German word "Brock," which means "badger" or "brock."
During the Middle Ages, many surnames were derived from occupations, physical characteristics, or associations with animals. The name Prock may have initially referred to someone who hunted or trapped badgers or had some connection to these animals. Alternatively, it could have been a nickname for someone with a stocky build or personal traits reminiscent of a badger.
One of the earliest known references to the name Prock can be found in the records of the town of Innsbruck, Austria, dating back to the late 1500s. These records mention a family with the surname Prock residing in the area during that period.
In the 17th century, the name appears in various church records and local documents across regions of Austria and southern Germany. For instance, Johann Prock, a farmer from the village of Neukirchen, was born in 1634 and lived until 1698.
As the centuries passed, the Prock surname spread across Europe, with some notable individuals bearing the name. One such person was Friedrich Prock, a renowned Austrian painter and engraver born in 1784 in Vienna. His works were widely acclaimed during his lifetime and can be found in several notable art collections.
Another notable figure was Wilhelm Prock, a German mathematician and physicist born in 1825 in Württemberg. He made significant contributions to the field of optics and was a professor at several prestigious universities in Germany.
In the late 19th century, the name Prock was associated with a prominent family in the town of Linz, Austria. Heinrich Prock, born in 1856, was a successful businessman and philanthropist who funded the construction of a local hospital and orphanage.
While the surname Prock may not be as common as some other European surnames, it has a rich history dating back several centuries, with roots deeply entrenched in the German-speaking regions of central Europe.
Demographics
Among Census respondents with the surname Prock, the largest self-reported group is White at 87.3%. The next largest groups are Two or More Races (6.0%) and Hispanic (3.7%).
The bar chart below shows how Prock 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 Prock 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.
