Origin
Meaning and origin of Korr
The surname KORR is believed to have originated in Germany, with its roots tracing back to the medieval period. It is derived from the German word "Korb," which means "basket" or "wicker basket." This suggests that the name may have originally referred to an occupation or trade involving the making or selling of baskets.
One of the earliest recorded instances of the surname KORR can be found in the town records of Heidelberg, Germany, dating back to the 14th century. In these records, a certain Heinrich Korr is mentioned as a resident of the town, indicating that the name was already in use during that era.
The name KORR also appears in various historical documents from the 16th and 17th centuries, particularly in regions of Germany such as Bavaria and Saxony. Some notable individuals bearing this surname include Johann Korr (1573-1642), a respected Lutheran theologian and author from Nuremberg, and Hans Korr (1611-1679), a prominent merchant and landowner in the city of Dresden.
In the 18th century, the KORR surname gained wider recognition with the birth of Friedrich Korr (1735-1819), a renowned German composer and musician who served as the Kapellmeister (music director) at the court of the Prince-Bishop of Würzburg.
Another notable figure was Karl Korr (1807-1886), a German educator and author who published several works on pedagogy and teaching methods. His contributions to the field of education were widely recognized during his lifetime.
As the centuries progressed, the KORR surname spread beyond Germany to other parts of Europe and eventually to other continents through migration and immigration. However, the name's origins and historical ties to the German regions remain firmly rooted.
It is worth noting that variations in spelling, such as Korr, Korres, and Korre, have also been observed throughout history, reflecting regional dialects and language influences.

The bar chart below shows how Korr 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 Korr 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.
