Origin
The surname Gantz is believed to have originated in Germany, with roots dating back to the 13th century. It is thought to be derived from the Germanic personal name "Ganz," which means "complete" or "whole." This name may have been given as a nickname to someone who was considered a wholesome or complete person.
In its earliest forms, the name was often spelled as "Ganz" or "Gantz." As the name spread across different regions of Germany, variations in spelling emerged, such as "Ganz," "Gantz," and "Gantze." These variations were likely influenced by local dialects and the preferences of record keepers.
One of the earliest recorded instances of the name can be found in the Bavarian town of Passau, where a "Johannes Gantz" was mentioned in a document from 1312. Another notable reference comes from the city of Nuremberg, where a "Hans Gantz" was listed as a resident in 1427.
In the 15th century, a "Peter Gantz" was recorded as a merchant in the city of Augsburg, suggesting that the name was associated with trade and commerce during that time period. Additionally, a "Konrad Gantz" was mentioned in a historical record from the city of Cologne in 1489.
As the name spread throughout Germany and into neighboring regions, it became associated with various place names. For instance, the town of Gantzkow in present-day Mecklenburg-Vorpommern, Germany, likely derived its name from the surname Gantz.
Historically, there have been several notable individuals bearing the surname Gantz. One such person was Johann Gantz (1592-1637), a German composer and organist who served at the court of the Elector of Saxony in Dresden. Another was Johann Gantz (1763-1829), a German painter and engraver known for his landscapes and portraits.
In the 19th century, a prominent figure with the surname Gantz was Georg Gantz (1818-1889), a German historian and writer who authored works on the history of the Hanseatic League and the city of Hamburg.
Another notable individual was Philipp Gantz (1856-1932), a German politician and member of the Reichstag, who represented the Social Democratic Party of Germany during the late 19th and early 20th centuries.
Lastly, Theodor Gantz (1885-1952) was a German architect and urban planner who designed several notable buildings in Berlin during the early 20th century, including the Schöneberg City Hall and the Deutsches Opernhaus.
Demographics
Among Census respondents with the surname Gantz, the largest self-reported group is White at 86.6%. The next largest groups are Black (6.5%) and Hispanic (3.0%).
The bar chart below shows how Gantz 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 Gantz surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Gantz (2000, 2010, 2020).
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.
