Origin
The surname Ruark is believed to have originated in Ireland, derived from the Gaelic name O'Ruairc or O'Rourke. This name is thought to have been derived from the ancient Irish words "O" meaning "descendant of" and "Ruairc" which was a personal name meaning "red king" or "red-haired."
The O'Rourke family were once powerful lords in the Irish province of Connacht and held sway over parts of what is now County Leitrim and County Roscommon. They trace their ancestry back to the legendary king Fergal O'Rourke who lived in the 7th century AD. The name Ruark is a anglicized form of this ancient Irish name.
One of the earliest recorded examples of the Ruark surname can be found in the Annals of Ulster, a chronicle of medieval Irish history. The name appears in an entry from 1171 which mentions a certain "Tiarnan O'Ruairc" who was then the King of Breifne.
The surname Ruark has also been associated with various place names in Ireland such as Lough Rourke in County Leitrim and Ballyrourke in County Laois. These places likely derive their names from the O'Rourke clan who once held lands in those areas.
Notable individuals with the surname Ruark include Robert Ruark (1915-1965), an American author and conservationist best known for works like "Something of Value" and "The Old Man and the Boy." Another was Ralph Ruark (1919-1982), an American television personality and game show host.
Edward T. Ruark (1922-2005) was an American physicist who made significant contributions to the field of nuclear physics. Mary Jane Ruark (1847-1916) was an American religious leader and founder of the Bible Missionary Church. And John Ruark (1819-1887) was a member of the Virginia secession convention in 1861 and later served in the Confederate Congress during the American Civil War.
Demographics
Among Census respondents with the surname Ruark, the largest self-reported group is White at 91.0%. The next largest groups are Two or More Races (4.4%) and Hispanic (2.6%).
The bar chart below shows how Ruark 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 Ruark 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 Ruark (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.
