Origin
The surname Clooney is believed to have originated in Ireland, specifically in the Gaelic regions of the country. The name is derived from the Irish Gaelic word "cluain," which means "meadow" or "pasture." It is likely that the name was initially used as a descriptive term for someone who lived near or worked in a meadow or pasture area.
The earliest recorded instances of the Clooney surname date back to the 16th century, with records indicating that the name was prevalent in counties such as Laois, Offaly, and Kilkenny. In these regions, the name was often spelled in various ways, including Cloney, Cluney, and Cloony, reflecting the linguistic variations and dialects present in different parts of Ireland at the time.
One of the earliest known references to the Clooney surname can be found in the Annals of the Four Masters, a chronicle of Irish history compiled in the early 17th century. The annals mention a branch of the O'Cluain family, which is believed to be an anglicized form of the Gaelic name Clooney.
Over the centuries, several notable individuals have borne the Clooney surname. One of the earliest was John Clooney (c. 1580-1660), an Irish Catholic priest who served as a chaplain in the Confederate War in Ireland during the 1640s. Another prominent figure was Michael Clooney (1766-1841), an Irish politician who served as a Member of Parliament for Portarlington in the early 19th century.
In more recent times, the Clooney surname has gained widespread recognition due to the fame of the American actor and filmmaker George Clooney, born in 1961. George Clooney's ancestors can be traced back to County Kilkenny, Ireland, where the Clooney surname has deep roots.
Other notable individuals with the Clooney surname include Nick Clooney (born 1934), an American television journalist and brother of George Clooney, and Rosemary Clooney (1928-2002), an American singer and actress who was a successful recording artist in the 1950s and 1960s.
While the Clooney surname may have evolved from a humble descriptive term for someone living in a meadow, it has since become associated with individuals who have made significant contributions to various fields, including religion, politics, entertainment, and journalism.
Demographics
Among Census respondents with the surname Clooney, the largest self-reported group is White at 91.7%. The next largest groups are Hispanic (3.4%) and Asian/Pacific Islander (1.9%).
The bar chart below shows how Clooney 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 Clooney 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.
