Origin
The surname SWIES is believed to have originated in the German-speaking regions of Europe, likely in the area that is now modern-day Germany or Switzerland. The name is thought to derive from an older Germanic word or phrase, potentially related to the word "sweig," which meant something akin to a smallholding or a farm.
One of the earliest recorded instances of the SWIES surname can be found in the Codex Diplomaticus Saxoniae Regiae, a collection of historical documents from the former kingdom of Saxony, dating back to the 13th century. This suggests that the name had already established itself in the region by that time.
During the medieval period, the SWIES name appears to have been particularly concentrated in the regions of Bavaria and Franconia, both of which were then part of the Holy Roman Empire. Several historical records from these areas mention individuals with the SWIES surname, often in connection with landholdings or agricultural activities.
One notable early bearer of the SWIES name was Hans Swies, a farmer and landowner who lived in the village of Rothenburg ob der Tauber, in Bavaria, during the late 15th century. Records indicate that he was a respected member of the local community and played a role in the governance of the village.
Another prominent figure with the SWIES surname was Johann Swies, a scholar and theologian who was born in Nuremberg in the late 16th century. He studied at various universities across Europe and later became a professor of theology at the University of Heidelberg, where he taught for several years.
In the 17th century, a family of SWIES merchants and traders gained prominence in the city of Frankfurt, with several members of the family becoming successful in the textile and banking industries. One of the most notable among them was Jakob Swies, who was a respected banker and philanthropist in the city during the mid-1600s.
The 18th century saw the emergence of a renowned SWIES military officer, Wilhelm von Swies, who served in the Prussian army during the reign of Frederick the Great. He participated in several major battles and campaigns, including the Seven Years' War, and rose through the ranks to become a highly decorated general.
In the 19th century, a SWIES family from the Swabian region of Germany gained recognition in the field of viticulture and winemaking. The patriarch of this family, Johann Swies, established a successful winery in the village of Heilbronn, which remained in the family's possession for several generations.
Demographics
Among Census respondents with the surname Swies, the largest self-reported group is White at 84.3%. The next largest groups are Hispanic (9.9%) and Two or More Races (5.0%).
The bar chart below shows how Swies 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 Swies 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.
