Origin
Meaning and origin of Loop
The surname LOOP is believed to have originated in the Netherlands, tracing its roots back to the 16th century. The name likely derives from the Dutch word "loop," meaning "loop" or "course," potentially referring to a physical feature or location associated with the family's origins.
One of the earliest recorded instances of the surname LOOP can be found in the Dutch municipal records of Leiden, dated 1587. The name appears in various spellings, such as "Loope," "Loopen," and "Loopt," reflecting the evolving orthography of the time.
Historical references to the name LOOP are scarce, but a notable mention can be found in the archives of the Dutch East India Company (VOC) from the 17th century. A merchant named Pieter LOOP is listed as having traded goods between the Netherlands and the Dutch East Indies.
In the 18th century, the LOOP surname gained prominence in the Netherlands, with several notable figures bearing the name. Jan LOOP (1707-1783) was a respected lawyer and legal scholar, known for his contributions to Dutch jurisprudence. Cornelis LOOP (1745-1819) was a celebrated painter, renowned for his landscape and portrait works.
As the Dutch colonized various parts of the world, the LOOP surname spread to other regions. In the late 18th century, a branch of the family settled in South Africa, where the name is still found today. Johannes LOOP (1770-1842) was one of the early Dutch settlers in the Cape Colony and established a successful farming enterprise.
The LOOP surname also found its way to North America, particularly in the 19th century. One of the earliest recorded instances is that of Hendrick LOOP (1812-1887), a Dutch immigrant who settled in New York and became a prominent businessman in the city's thriving commercial district.
Another notable bearer of the LOOP surname was Gerrit LOOP (1830-1907), a Dutch-born American engineer who played a crucial role in the construction of several major bridges and railway projects in the United States during the late 19th century.
Over the centuries, the LOOP surname has continued to be present in various parts of the world, carrying the legacy of its Dutch origins while adapting to new cultural and linguistic environments.

The bar chart below shows how Loop 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 Loop surname at the time of the 2020 Census, not any inherent property of the name itself.

Is this page using the latest Census data?
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 Loop (2000, 2010, 2020).
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. 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.
