Origin
The surname Swartz has its origins in Germany, with records dating back to the 13th century. It is believed to be derived from the German word "schwarz," meaning "black," which could have been used as a descriptive name for someone with dark hair or complexion, or perhaps referring to their occupation or place of residence.
One of the earliest recorded instances of the name can be found in the town records of Mühlhausen, Thuringia, where a certain Heinricus Swartz was mentioned in 1285. The name also appears in various other historical documents from the region, such as the Stadtbücher (city books) of Erfurt and the Urkundenbücher (charter books) of Hessen.
In the 14th century, the name spread to other parts of Germany, with variations in spelling such as Schwartz, Schwarz, and Swarz. The town of Schwäbisch Hall in Baden-Württemberg had a notable family of Swartz tanners and furriers who were influential in the local guild system.
One of the earliest known bearers of the name was Johannes Swartz, a Catholic theologian and preacher who lived in Nuremberg from around 1450 to 1510. He was known for his fiery sermons and his criticism of the excesses of the Church.
In the 16th century, the name gained prominence with the astronomer and mathematician Caspar Swartz (1501-1561), who was born in Holzheim, Bavaria. He is best known for his work on comets and for his contributions to the development of the Gregorian calendar.
Another notable figure was the Swedish botanist Olof Swartz (1760-1818), who made significant contributions to the study of plant life in the West Indies and South America. He is credited with the discovery and classification of numerous plant species, and his work was instrumental in the development of modern taxonomy.
During the 19th century, the name spread further across Europe and to other parts of the world, including North America, where it was often anglicized to "Schwartz." One of the most famous bearers of the name was the Hungarian-American business magnate and philanthropist George Swartz (1857-1923), who made his fortune in the steel industry and was a major benefactor of educational institutions in the United States.
Other notable individuals with the surname Swartz include the German-American painter and printmaker Rudolf Swartz (1839-1907), the Swedish composer and pianist Franz Berwald (originally Franz Adolf Swartz, 1796-1868), and the American botanist Olga Hartman Swartz (1920-2010), who made significant contributions to the study of mosses and liverworts.
Demographics
Among Census respondents with the surname Swartz, the largest self-reported group is White at 92.1%. The next largest groups are Two or More Races (3.2%) and Hispanic (2.6%).
The bar chart below shows how Swartz 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 Swartz 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.
