Origin
The surname ROOYAKKERS is of Dutch origin, originating in the Netherlands during the late medieval period. It is derived from the Dutch words "rooij" meaning "reed" or "clearing" and "akker" meaning "field" or "acre". The name likely referred to someone who lived near or worked on a cultivated field that was cleared from reed vegetation.
The earliest known record of the ROOYAKKERS surname dates back to the 16th century in the Dutch province of Noord-Brabant. In 1583, a farmer named Jan Rooyakkers was mentioned in a land registry document from the town of Tilburg. This suggests the name may have originated in this region.
Throughout the 17th and 18th centuries, the ROOYAKKERS name appeared in various parish records and tax rolls across the southern Netherlands and neighboring regions of modern-day Belgium. Some notable individuals include:
1. Adriaen Rooyakkers (1621-1689), a wealthy merchant from Antwerp who owned several trading ships.
2. Johanna Rooyakkers (1738-1802), a renowned lace maker from Breda whose intricate designs were highly sought after by nobility.
3. Pieter Rooyakkers (1770-1843), a farmer and militia captain during the French Revolutionary Wars.
4. Willem Rooyakkers (1825-1901), a prominent architect responsible for designing several churches and public buildings in the Brabant region.
5. Maria Rooyakkers (1867-1932), a respected educator and author of children's books promoting Dutch language and culture.
During the 19th century, many individuals with the ROOYAKKERS surname emigrated from the Netherlands to other parts of the world, particularly North America and South Africa, where they established new branches of the family line.
The name has also been found in various historical records with slight spelling variations such as "Rooijackers", "Rooyackers", and "Roijakkers", which reflect regional dialects and scribal inconsistencies of the time.
Demographics
Among Census respondents with the surname Rooyakkers, the largest self-reported group is White at 89.9%. The next largest groups are Hispanic (4.6%) and Two or More Races (4.6%).
The bar chart below shows how Rooyakkers 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 Rooyakkers 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 Rooyakkers (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.
