Origin
The surname Nolan has its origins in Ireland, where it first appeared in the 10th century. It is derived from the Irish Gaelic words "O'Nualláin," meaning "descendant of Nualláin." Nualláin was an ancient personal name that may have meant "famous" or "shout."
The Nolan family is believed to have originated in County Carlow, in the southeast of Ireland. The name is also found in County Kilkenny and other parts of Leinster. Early forms of the name included O'Nualláin, O'Nuallain, and O'Nolan.
One of the earliest recorded instances of the Nolan surname is found in the Annals of the Four Masters, a chronicle of medieval Irish history. In the year 1014, it mentions a man named Gilla Pádraig Ó Nualláin, who was the chief poet of Ireland.
In the 16th century, the Nolan family possessed lands in County Carlow, particularly in the barony of Forth. A notable figure from this time was Patrick Nolan, a Catholic priest who was executed in 1579 for his religious beliefs during the Elizabethan persecutions.
Another prominent individual was Michael Nolan (1798-1876), an Irish-born architect who designed numerous buildings in Canada, including the Notre-Dame Basilica in Montreal. He was a leading figure in the Neoclassical architectural style in Canada during the 19th century.
In the United States, one of the earliest recorded instances of the Nolan surname was Benjamin Nolan (1752-1836), a military officer who served in the American Revolutionary War. He later became a distinguished judge in Kentucky.
In the 20th century, Christopher Nolan (born 1970) is a renowned British-American film director known for acclaimed works such as "Inception," "The Dark Knight" trilogy, and "Dunkirk." He has won numerous awards, including an Academy Award and several BAFTAs.
Other notable individuals with the surname Nolan include Sir Sidney Nolan (1917-1992), an Australian artist known for his paintings depicting the outback and figures from Australian history, and Lloyd Nolan (1902-1985), an American actor who appeared in numerous films and television shows during the Golden Age of Hollywood.
Demographics
Among Census respondents with the surname Nolan, the largest self-reported group is White at 84.3%. The next largest groups are Black (7.2%) and Hispanic (4.0%).
The bar chart below shows how Nolan 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 Nolan 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.
