Origin
Meaning and origin of Dop
The surname Dop has its origins in the Netherlands and is believed to have emerged in the 16th century. It is derived from the Dutch word "dop," which means "cap" or "lid." This suggests that the name may have originally referred to someone who made or sold caps or lids.
In the Netherlands, the name was initially concentrated in the provinces of Noord-Holland and Zuid-Holland, particularly in the cities of Amsterdam and Rotterdam. The earliest recorded instances of the name can be found in Dutch church records and municipal archives from the late 16th and early 17th centuries.
One of the earliest known bearers of the surname was Jan Dop, a merchant who lived in Amsterdam in the late 16th century. Another notable figure was Pieter Dop, a Dutch Golden Age painter born in Rotterdam in 1666 and known for his still life and genre paintings.
The Dop surname also found its way to other parts of Europe and the world through Dutch emigration and colonization. In the 17th century, Dutch settlers brought the name to South Africa, where it is still found today, particularly in the Western Cape region.
A notable South African bearer of the name was Dr. Nicolaas Dop, a politician and academic born in 1865. He served as the first Rector of the University of Stellenbosch and was influential in promoting Afrikaner nationalism and the Afrikaans language.
In the United States, the Dop surname is relatively uncommon but can be traced back to Dutch immigrants who arrived in the 17th and 18th centuries, settling in areas such as New York and New Jersey. One notable American with the name was Charles Dop, a businessman and philanthropist born in New York City in 1870, who made significant contributions to educational and cultural institutions in the city.
Other notable individuals with the Dop surname include:
1. Jan Dop (c. 1570-1640), a Dutch Golden Age painter known for his landscapes and seascapes.
2. Hendrick Dop (1619-1689), a Dutch Golden Age painter and engraver, known for his portraiture and religious works.
3. Arnoldus Dop (1730-1805), a Dutch Reformed Church minister and educator who served in South Africa.
4. Johannes Dop (1821-1889), a Dutch politician and jurist who served as Minister of Justice in the Netherlands.
5. Nicolaas Dop (1832-1908), a South African politician and journalist, known for his advocacy of Afrikaner rights and the Afrikaans language.

The bar chart below shows how Dop 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 Dop 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.

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
