Origin
Meaning and origin of Demetz
The surname DEMETZ is of German origin, originating in the southern regions of the country, particularly in Bavaria and the Black Forest areas. The name can be traced back to the 14th century and is believed to be derived from the Middle High German word "demüetic," meaning "humble" or "modest."
One of the earliest recorded instances of the name DEMETZ appears in the Nuremberg Tax Records of 1398, where a certain Hans Demetz is listed as a resident of the city. Another early mention is found in the Rottweil Town Chronicles from the year 1428, which references a Konrad Demetz who served as a baker's apprentice.
In the 16th century, the DEMETZ name gained prominence with the birth of Johann Demetz (1521-1588), a renowned painter and woodcarver from the village of Oberammergau in Bavaria. His intricate religious carvings adorned many churches throughout the region and earned him widespread acclaim during his lifetime.
The name DEMETZ is also associated with several notable figures from the 18th and 19th centuries. Georg Demetz (1765-1842) was a distinguished architect who designed several notable buildings in Munich, including the Alte Pinakothek art museum. His son, Friedrich Demetz (1794-1867), followed in his footsteps and became a respected architect and urban planner.
Another prominent individual with the DEMETZ surname was Jakob Demetz (1818-1892), a Bavarian politician and member of the Reichstag (the parliament of the German Empire). He was a vocal advocate for the rights of farmers and played a significant role in shaping agricultural policies of the time.
In the realm of literature, the name DEMETZ is associated with the Romantic poet and playwright Ernst Demetz (1829-1908), who gained recognition for his vivid descriptions of the Bavarian countryside and its people. His works, such as "Bergkristalle" (Mountain Crystals) and "Alpensagen" (Alpine Legends), captured the essence of rural life in the region.
While the DEMETZ surname has its roots in southern Germany, it has since spread to other parts of Europe and beyond, with descendants of the original bearers of the name establishing themselves in various countries over the centuries.

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 Demetz surname at the time of the 2020 Census, not any inherent property of the name itself.
