Origin
The surname OPBROEK originated in the Netherlands, specifically in the northern provinces of Friesland and Groningen, during the 16th and 17th centuries. It is derived from the Dutch words "op" meaning "on" and "broek" meaning "marsh" or "bog." The name likely referred to someone who lived or worked on a marshy area or reclaimed land.
One of the earliest recorded instances of the name OPBROEK can be found in the records of the Dutch Reformed Church in the village of Bedum, Groningen, where a certain Rykle Opbroek was mentioned in 1642. Another early reference is from the town of Leeuwarden in Friesland, where a Jan Opbroek was listed as a property owner in 1657.
The OPBROEK surname has also been connected to several place names in the Netherlands, particularly the hamlet of Opbroek in the municipality of Eemsdelta, Groningen. This small settlement was originally known as "Opbroek-ter-Muntendam" or "Opbroek near Muntendam," suggesting that the name was derived from the geographic location.
Throughout history, there have been several notable individuals bearing the OPBROEK surname. One of the earliest was Pieter Opbroek (1595-1668), a Dutch merchant and ship owner who was involved in the early Dutch settlements in the Americas. Another prominent figure was Johannes Opbroek (1748-1824), a Dutch Reformed minister and theologian who served as the pastor of the Westerkerk in Amsterdam.
In the 19th century, Gerrit Opbroek (1815-1892) gained recognition as a Dutch landscape painter, known for his depictions of rural scenes and farm life. His contemporary, Pieter Opbroek (1823-1899), was a successful businessman and philanthropist who founded the Opbroek Foundation for the education of underprivileged children in the city of Groningen.
More recently, Jaap Opbroek (1919-2002) was a Dutch resistance fighter during World War II and later served as a member of the Dutch Parliament for the Christian Democratic Appeal party.
While the OPBROEK surname has its roots in the Netherlands, it has since spread to other parts of the world, particularly through emigration and settlement in other countries. However, the name remains closely tied to its Dutch heritage and the historical significance of its origins in the northern provinces of the Netherlands.
Demographics
Among Census respondents with the surname Opbroek, the largest self-reported group is White at 91.2%. The next largest groups are Two or More Races (4.4%) and Hispanic (2.6%).
The bar chart below shows how Opbroek 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 Opbroek 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.
