Origin
The surname DOOP has its origins in the Netherlands, where it first appeared in the 16th century. It is believed to have been derived from the Dutch word "doop," meaning "baptism" or "christening." This suggests that the name may have been initially bestowed upon someone who was closely associated with the church or baptismal rites.
One of the earliest recorded instances of the DOOP surname can be found in the archives of the city of Amsterdam, where a certain Jan Doop was mentioned in a document dated 1572. This particular entry provides valuable insight into the early use of the name and its geographical distribution within the Netherlands.
During the 17th century, the DOOP name gained prominence in the region of Friesland, a northern province of the Netherlands. Several notable individuals bearing this surname emerged from this area, including Pieter Doop (1605-1678), a renowned scholar and theologian who authored several influential works on religious philosophy.
As Dutch colonization and exploration expanded in the 17th and 18th centuries, the DOOP name began to appear in various Dutch settlements across the globe. One such example is Gerrit Doop (1712-1784), a merchant and trader who established a successful business in the Dutch East Indies (present-day Indonesia).
The DOOP surname also found its way to the New World, with several families settling in the Dutch colonies of New Netherland (later becoming New York and New Jersey). One notable figure from this period was Cornelis Doop (1688-1754), a farmer and landowner who played an instrumental role in the development of the Dutch community in what is now Long Island, New York.
In more recent times, the DOOP name has continued to be associated with individuals of Dutch descent, although it has also spread to other parts of the world through migration and intermarriage. A few notable figures include the Dutch artist Willem Doop (1825-1892), known for his landscapes and seascapes, and the American author and playwright Hendrik Doop (1904-1988), whose works explored themes of identity and cultural assimilation.
Demographics
Among Census respondents with the surname Doop, the largest self-reported group is White at 78.6%. The next largest groups are Hispanic (8.9%) and Two or More Races (7.1%).
The bar chart below shows how Doop 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 Doop surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Doop (2000, 2010, 2020).
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.
