Origin
The surname KATJE originated in the Netherlands during the 16th century. It is derived from the Dutch word "katje," which means "little cat." This name likely emerged as a nickname or descriptive term for someone who was known for their feline-like qualities or had a particular fondness for cats.
The earliest recorded instances of the KATJE surname can be found in Dutch parish records and historical documents from the late 1500s and early 1600s. These early mentions often appear as variations of the spelling, such as "Catje," "Kattje," or "Kaatje," reflecting the regional dialects and linguistic variations of the time.
One notable historical figure bearing the KATJE name was Jan Katje (1592-1657), a Dutch painter and engraver known for his landscapes and cityscapes. His works can be found in various museums and collections throughout the Netherlands and Europe.
Another individual of note was Pieter Katje (1647-1712), a Dutch merchant and sea captain who played a role in the early colonization of the Cape of Good Hope region in South Africa. Records indicate that he made several voyages to the area in the late 17th century.
In the 18th century, the KATJE surname appeared in the Dutch East Indies (present-day Indonesia). Cornelis Katje (1721-1789) was a prominent figure in the Dutch East India Company, serving as a merchant and colonial administrator in Batavia (now Jakarta).
Moving into the 19th century, the KATJE name can be found in Dutch immigrant communities across Europe and beyond. One such example is Adriana Katje (1823-1901), a Dutch woman who immigrated to the United States in the mid-1800s and settled in the state of Michigan.
Another notable bearer of the KATJE surname was Willem Katje (1871-1945), a Dutch artist and illustrator known for his intricate etchings and woodcuts depicting scenes from everyday life in the Netherlands.
Throughout its history, the KATJE surname has maintained its connections to the Netherlands and Dutch culture, while also spreading to various parts of the world through migration and exploration.
Demographics
Among Census respondents with the surname Katje, the largest self-reported group is White at 97.1%. The next largest groups are Hispanic (1.9%) and Two or More Races (1.0%).
The bar chart below shows how Katje 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 Katje 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.
