Origin
Meaning and origin of Kaumans
The surname KAUMANS is of Dutch origin, with its roots traced back to the Middle Ages in the Netherlands. It is believed to have originated as a locational name, derived from a place called Kaumen or Kauman, which was likely a small village or hamlet in the region.
The earliest known record of the KAUMANS name dates back to the 15th century, when a certain Henrick Kaumans was mentioned in a local registry from the town of Leiden in 1472. This suggests that the name had already been established and in use for some time prior to this record.
In the 16th century, the KAUMANS name appeared in several historical documents, including the records of the Dutch East India Company (VOC). One notable figure from this era was Jan Kaumans, a merchant and explorer who sailed with the VOC to the East Indies in the early 1600s.
As the Dutch expanded their influence globally, the KAUMANS name spread to various regions, including the Dutch colonies in the Americas and the Cape of Good Hope in South Africa. In the 17th century, a certain Pieter Kaumans was recorded as one of the early settlers in the Dutch Cape Colony.
The KAUMANS name also found its way into the literary world, with a Dutch poet and playwright named Joost Kaumans gaining recognition in the late 18th century. His works, which often explored themes of love and nature, were celebrated in his time and remain a part of the Dutch literary canon.
Another notable figure bearing the KAUMANS name was Willem Kaumans, a Dutch military officer who served in the Napoleonic Wars in the early 19th century. He rose through the ranks and earned distinctions for his bravery and leadership on the battlefield.
Over the centuries, variations of the KAUMANS spelling emerged, including Kaumans, Kaumaan, and Kaumanns, reflecting regional differences and linguistic evolution. Despite these minor spelling changes, the name has maintained its Dutch roots and historical significance.

The bar chart below shows how Kaumans 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 Kaumans 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.
