Origin
Meaning and origin of Mantz
The surname "MANTZ" is believed to have originated in Germany, with roots dating back to the 13th century. It is thought to be a variant spelling of the German word "Mantz," which means "small" or "short." This suggests that the name was likely given as a nickname to someone of shorter stature.
In the early records, the name appeared with various spellings, such as "Mantze," "Mantz," and "Mantzs." One of the earliest documented instances of the name can be found in the Codex Diplomaticus Anhaltinus, a collection of historical documents from the former principality of Anhalt, which mentions a "Henricus Mantze" in the year 1286.
The name also appears in the Bürgermeisterbuch, a registry of town mayors in the city of Erfurt, Thuringia, where a "Hermannus Mantz" is recorded as holding the position in 1357. This provides evidence of the surname's presence in central Germany during the medieval period.
One notable bearer of the Mantz surname was Johann Mantz (c. 1480-1548), a German reformer and Protestant theologian who played a significant role in the Reformation. He was a close associate of Martin Luther and served as a deacon in the city of Wittenberg.
Another prominent figure was Johann Friedrich Mantz (1650-1726), a German theologian and philosopher who held the position of rector at the University of Wittenberg. He was recognized for his contributions to the fields of ethics and natural law.
In the 18th century, Johann Georg Mantz (1717-1789) was a renowned German architect and urban planner. He was responsible for designing several notable buildings in the city of Mannheim, including the iconic Mannheim Palace.
The name Mantz also has ties to the town of Mantz, located in the state of Saxony-Anhalt, Germany. It is possible that the surname originated from this place name, although the exact connection remains unclear.
Throughout history, the Mantz surname has been carried by individuals from various walks of life, including academics, clergy members, architects, and civic leaders, leaving their mark on the cultural and intellectual landscape of Germany.

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 Mantz 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 Mantz (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
