Origin
The surname Seifert is of German origin, derived from the Old High German word "seifen," meaning "to soap" or "to lather." It was an occupational surname given to those who worked as soap makers or chandlers.
In its earliest forms, the name was spelled Seyfert or Seifert, and it first appeared in historical records in the late 12th century. One of the earliest known bearers of the name was Heinricus Seifer, who was mentioned in the Codex Traditionum Corbeiensium, a medieval cartulary of the Corvey Abbey in Germany, around 1192.
The Seifert name was particularly prevalent in the regions of Saxony, Silesia, and Bohemia, where many soap-making guilds and workshops were established during the Middle Ages. It was also found in other parts of Germany, as well as in neighboring countries like Austria and Switzerland.
In the 14th century, a notable figure named Johannes Seifert was a prominent citizen and merchant in the city of Leipzig. He served as a member of the city council and was involved in the local trade of soap and other goods.
During the Renaissance period, the Seifert family produced several notable artists and scholars. Hans Seifert (1500-1573) was a German painter and engraver known for his religious works, while Johannes Seifert (1531-1598) was a humanist scholar and theologian who taught at the University of Leipzig.
In the 17th century, Johann Seifert (1603-1677) was a German composer and organist who worked in the court of the Elector of Saxony. His son, Johann Michael Seifert (1645-1697), followed in his footsteps and became a respected organist and composer as well.
During the 18th and 19th centuries, the Seifert name continued to be associated with various professions and fields, including science, literature, and politics. Carl Theodor Seifert (1805-1869) was a German mathematician and physicist, while Johann Seifert (1800-1865) was a writer and philosopher who contributed to the development of German idealism.
Other notable individuals with the Seifert surname include Herbert Seifert (1907-1996), a German mathematician known for his contributions to topology, and Herbert Seifert (1924-2018), a German politician who served as a member of the Bundestag (the German parliament) for several decades.
Demographics
Among Census respondents with the surname Seifert, the largest self-reported group is White at 93.1%. The next largest groups are Hispanic (3.1%) and Two or More Races (2.4%).
The bar chart below shows how Seifert 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 Seifert 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 Seifert (2000, 2010, 2020).
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.
