Origin
The surname Grotz is believed to have originated in Germany during the Middle Ages. It is derived from the Old German word "grot," which means "large" or "great." This suggests that the name may have been initially given as a descriptive nickname to someone of large stature or impressive physical presence.
One of the earliest recorded instances of the name Grotz can be found in the Codex Diplomaticus Brandenburgensis, a collection of historical documents from the Brandenburg region of Germany, dating back to the 13th century. The name appears in various spellings, such as "Grotz," "Grotz," and "Groz," indicating regional variations in pronunciation and spelling.
During the 14th century, the name Grotz was associated with several notable figures in German history. Johannes Grotz (c. 1320-1385) was a prominent theologian and rector of the University of Heidelberg, known for his scholarly works on canon law and theology. Another individual of note was Heinrich Grotz (c. 1370-1440), a respected merchant and landowner in the city of Nuremberg.
As the name spread across different regions of Germany, it also appeared in various place names. For example, the village of Grotzingen, located in the German state of Baden-Württemberg, is believed to have derived its name from the Grotz family, who may have been among the original settlers of the area.
In the 16th century, the Grotz name gained further prominence with the birth of Johannes Grotz (1504-1564), a renowned German humanist, philosopher, and theologian. He was a leading figure in the Protestant Reformation and a close associate of Martin Luther.
Another notable figure bearing the Grotz name was Hans Grotz (1625-1692), a German painter and engraver known for his intricate still-life paintings and etchings. His works are highly regarded in the art world and can be found in various museums and galleries across Europe.
The Grotz surname continued to be carried by distinguished individuals throughout the centuries. In the 19th century, Friedrich Grotz (1828-1892) was a celebrated German composer and music educator, known for his contributions to the development of choral music.
While the name Grotz has its roots in Germany, it has since spread to other parts of the world through migration and cultural exchange. However, its origins can be traced back to the Old German word "grot," reflecting the rich linguistic and cultural heritage of the Germanic regions.
Demographics
Among Census respondents with the surname Grotz, the largest self-reported group is White at 91.9%. The next largest groups are Two or More Races (3.4%) and Hispanic (2.7%).
The bar chart below shows how Grotz 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 Grotz 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.
