Origin
The surname HRUZ has its origins in the Czech Republic, dating back to the 12th century. It is believed to be derived from the Old Czech word "hruz," which translates to "horror" or "terror." This suggests that the name may have been given to someone who had a particularly fearsome or intimidating presence.
In the early medieval period, the HRUZ name was predominantly found in the regions of Bohemia and Moravia, which were the historical lands of the Czech people. One of the earliest recorded mentions of the name can be found in the Codex Diplomaticus et Epistolaris Regni Bohemiae, a collection of historical documents from the Czech lands, where a certain Petr HRUZ is mentioned in a land transaction from the year 1327.
The name HRUZ also appears in several other ancient manuscripts and chronicles from the region, including the Chronica Bohemorum by Cosmas of Prague, written in the 12th century. This suggests that the name had already become well-established among the Czech nobility and gentry by that time.
One notable bearer of the HRUZ surname was Jan HRUZ, a Czech soldier and military commander who fought in the Hussite Wars of the 15th century. He was born around 1395 and gained renown for his bravery and tactical skills on the battlefield.
Another significant figure with this surname was Vaclav HRUZ, a renowned Czech painter and engraver who lived in the 16th century. He was known for his intricate and detailed works, many of which depicted religious scenes and themes.
In the 18th century, a prominent Czech sculptor named Josef HRUZ gained recognition for his elaborate baroque-style sculptures and architectural decorations, which adorned many churches and palaces throughout the Czech lands.
A more recent historical figure with the HRUZ surname was Frantisek HRUZ, a Czech geologist and paleontologist who lived from 1867 to 1938. He made significant contributions to the study of fossils and ancient geological formations in the Czech Republic.
While the name HRUZ is relatively uncommon outside of the Czech Republic, it has maintained a strong presence in its homeland, with many families proudly carrying on the tradition of this ancient Czech surname.
Demographics
Among Census respondents with the surname Hruz, the largest self-reported group is White at 98.2%. The next largest groups are Hispanic (1.8%).
The bar chart below shows how Hruz 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 Hruz 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.
