Origin
Meaning and origin of Hartmann
The surname Hartmann is of German origin and dates back to the Middle Ages. It is derived from the Germanic words "hart" meaning "hard, strong" and "mann" meaning "man". The name originally referred to a strong, brave, or hardworking individual.
One of the earliest recorded instances of the name Hartmann can be found in the Codex Traditionum Corbeiensium, a medieval cartulary from the Corvey Abbey in present-day North Rhine-Westphalia, Germany, dating back to the 9th century. The name appears in various forms, such as Hartmannus, Hartmanno, and Hartman.
In the 11th century, a notable figure bearing the name Hartmann was Hartmann von Aue, a renowned German poet and author of courtly romance literature. He lived from around 1160 to 1220 and is best known for his works "Erec" and "Iwein".
Another prominent individual with the surname Hartmann was Hartmann Schedel, a German physician, humanist, and historian who lived from 1440 to 1514. He is credited with producing the Nuremberg Chronicle, one of the most richly illustrated and influential works of the early print era.
In the 16th century, Johann Hartmann, a German composer and organist, made significant contributions to the development of Protestant church music. He lived from around 1568 to 1631 and served as the court organist in Dresden.
The surname Hartmann was also associated with various place names in German-speaking regions, such as Hartmannsdorf, Hartmannshausen, and Hartmannsweiler, reflecting the widespread use of the name throughout German history.
One of the most famous bearers of the name in modern times was Karl Amadeus Hartmann, a German composer who lived from 1905 to 1963. He is renowned for his orchestral works, including the symphonies "Miserae" and "Sinfonia Tragica", which were influenced by the events of World War II.

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

Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
