Origin
Meaning and origin of Deuz
The surname DEUZ has its origins in Germany, with records dating back to the 12th century. Initially, it was spelled as "Deutz" and is believed to be derived from the Old German word "deut," which means "people" or "nation." This suggests that the name may have initially referred to someone who belonged to a particular community or ethnic group.
One of the earliest recorded instances of the name DEUZ can be found in the Codex Eberhardi, a medieval manuscript from the 12th century that contains records of land ownership and property transactions in the region of Deutz, near Cologne. This manuscript mentions several individuals with the surname DEUZ, indicating that the name was well-established in that area during that time period.
The surname DEUZ is also associated with the town of Deutz, which is now a part of the city of Cologne. The town was first mentioned in historical records in the 9th century, and it is possible that some of the earliest bearers of the DEUZ surname were from this area or had connections to it.
One notable individual with the surname DEUZ was Johannes Deuz, a German theologian and philosopher who lived in the 15th century (c. 1420-1492). He was a renowned scholar and taught at the University of Cologne, making significant contributions to the field of medieval scholasticism.
Another influential figure was Gottfried Deuz (1554-1626), a German composer and organist who served as the Kapellmeister (chapel master) at the court of the Elector of Saxony in Dresden. His compositions, particularly his sacred works, were highly regarded during his lifetime and helped establish the reputation of the Dresden court as a center of musical excellence.
In the 16th century, there are records of a family with the surname DEUZ living in the town of Worms, located in the Rhineland-Palatinate region of Germany. One member of this family, Hans Deuz (c. 1520-1589), was a prominent merchant and civic leader who served as a member of the town council and played a significant role in the local government.
The surname DEUZ also appears in historical records from other parts of Germany, such as Bavaria and Saxony, indicating that the name had spread to various regions over time. In the 17th century, a notable figure was Johann Deuz (1625-1697), a Lutheran theologian and professor at the University of Wittenberg, who wrote extensively on theological and philosophical topics.
Throughout its history, the surname DEUZ has been associated with various professions and occupations, including scholars, musicians, merchants, and civic leaders. While the exact origins of the name remain somewhat uncertain, its longevity and presence in different regions of Germany attest to its deep roots and significance in the country's history and culture.

The bar chart below shows how Deuz 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 Deuz surname at the time of the 2020 Census, not any inherent property of the name itself.

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.

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
