The surname KAHL originated in Germany and is believed to have derived from a medieval German word meaning "bald" or "hairless". It likely started as a nickname for someone who had little or no hair, which was then adopted as a hereditary surname.
The earliest recorded instances of the name KAHL can be traced back to the 13th century in various regions of Germany, particularly in areas like Bavaria and Saxony. Some of the earliest known spellings include Kale, Kahle, and Kahll.
In the 14th century, the name KAHL appeared in several historical records and documents, including the Codex Diplomaticus Brandenburgensis, a collection of historical documents related to the Margraviate of Brandenburg. This suggests that individuals with the surname KAHL were present in that region during that time period.
One notable early bearer of the name KAHL was Johannes Kahl, a German scholar and theologian who lived in the 15th century (c. 1438-1508). He was known for his work on biblical exegesis and his teachings at the University of Leipzig.
Another historical figure with the surname KAHL was Johann Kahl, a German painter who lived in the 16th century (c. 1530-1600). He was known for his religious paintings and worked primarily in the city of Nuremberg.
In the 17th century, the name KAHL appeared in records related to the Thirty Years' War (1618-1648), which ravaged parts of Germany. Many individuals with the surname KAHL were likely affected by the conflict and its aftermath.
One notable bearer of the name during this time was Hans Kahl, a German soldier and military leader who served in the Imperial Army during the Thirty Years' War (c. 1590-1650). He was known for his bravery and tactical skills in battle.
In the 18th century, the name KAHL was also found in various records and documents related to the German states and principalities, suggesting that individuals with this surname continued to have a presence in different regions of what is now modern-day Germany.

Demographics
Among Census respondents with the surname Kahl, the largest self-reported group is White at 92.6%. The next largest groups are Hispanic (3.2%) and Two or More Races (3.1%).
The bar chart below shows how Kahl 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 Kahl 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.
