The surname Klarmann is of German origin, with its roots dating back to the Middle Ages. It is believed to have originated in the southern regions of Germany, particularly in the areas around Bavaria and Baden-Württemberg.
The name Klarmann is derived from the German word "Klar," which means "clear" or "bright," and the suffix "-mann," which signifies a person or an individual. It is likely that the name was initially given as a descriptive nickname to someone with a clear or bright complexion or personality.
One of the earliest recorded instances of the name Klarmann can be found in the Codex Diplomaticus Saxoniae, a collection of historical documents from Saxony, dating back to the 13th century. In this record, a certain "Henricus Klarmann" is mentioned as a landowner in the region.
During the 14th century, the name Klarmann appeared in several local administrative records and chronicles, such as the Urkundenbuch der Stadt Nürnberg (Book of Charters of the City of Nuremberg), where a "Hans Klarmann" was documented as a respected citizen and merchant.
In the 16th century, a notable figure bearing the name Klarmann was Johann Klarmann (1505-1567), a Lutheran theologian and reformer from Saxony. He played a significant role in the Protestant Reformation and was a close associate of Martin Luther.
Another historical figure with the surname Klarmann was Friedrich Klarmann (1770-1847), a German writer and poet from Württemberg. He was known for his works celebrating the natural beauty of the Black Forest region.
In the 19th century, a prominent Klarmann was Heinrich Klarmann (1825-1891), a German industrialist and entrepreneur who founded the Klarmann Machinery Company in Stuttgart, which became a leading manufacturer of textile machinery.
Another notable individual with the surname Klarmann was Emilie Klarmann (1867-1944), a German philanthropist and social activist from Baden. She dedicated her life to improving the living conditions of underprivileged children and establishing orphanages and schools.

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

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
