Origin
The surname Keyser is of German origin, derived from the German word "Keiser" meaning "emperor" or "caesar." The name first emerged during the medieval period, likely in the 12th or 13th century, and was originally used to identify individuals who worked for or had some association with the imperial court or the Holy Roman Empire.
One of the earliest recorded instances of the name Keyser can be found in the Codex Diplomaticus Saxoniae Regiae, a collection of medieval documents from the German region of Saxony, which mentions a certain "Hermannus Keiser" in a document dated 1202. This suggests that the name was already in use by the early 13th century.
In the 14th century, the name Keyser appeared in various historical records across German-speaking regions, including the Annales Colonienses, a medieval chronicle from Cologne, which mentions a "Johannes Keyser" in an entry from 1376.
The name Keyser was also associated with certain place names, such as Keyserlingk, a village in what is now Mecklenburg-Vorpommern, Germany, which was first mentioned in a document from 1350 as "Keyserlinge," likely referring to the presence of individuals bearing the Keyser surname in the area.
One of the earliest notable individuals with the surname Keyser was Johann Keyser (c. 1520-1586), a German Protestant theologian and reformer who played a significant role in the Reformation in Saxony.
Another notable figure was Adriaen Keysers (c. 1560-1615), a Dutch engraver and printmaker who was active in Antwerp during the late 16th and early 17th centuries.
In the 18th century, Johann Georg Keyser (1693-1740) was a German architect and builder who worked in Saxony and designed several notable buildings, including the Frauenkirche in Dresden.
The 19th century saw the rise of Nicola Keyser (1835-1909), a German industrialist and founder of the Keyser'sche Maschinenbauanstalt, a leading manufacturer of industrial machinery based in Chemnitz, Saxony.
Lastly, Rudolf Keyser (1877-1946) was a German-American lawyer and judge who served as a justice on the New York Supreme Court and played a role in the prosecution of high-profile criminal cases in the early 20th century.
Demographics
Among Census respondents with the surname Keyser, the largest self-reported group is White at 90.5%. The next largest groups are Hispanic (3.3%) and Two or More Races (3.2%).
The bar chart below shows how Keyser 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 Keyser 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.
