Origin
The surname McCourt is of Irish origin, derived from the Gaelic surname Mac Cuarta, which translates to "son of Cuarta." The name Cuarta is thought to have been a personal name derived from the Old Irish word "cuarta," meaning "skilled" or "dexterous."
The McCourt surname can be traced back to the 12th century in Ireland, particularly in the counties of Ulster and Connacht. It is believed to have originated among the Uí Briúin dynasty, a powerful family that ruled over regions of Connacht and Ulster during the Middle Ages.
One of the earliest recorded instances of the McCourt name appears in the Annals of Ulster, a chronicle of medieval Irish history. In the year 1201, the Annals mention a "Gillacuarta Mac Cuarta" as a participant in a battle between rival Irish clans.
In the 16th century, the McCourt surname is found in various Irish records, including the Fiants of the Tudor Sovereigns, which were administrative documents issued by the English Crown in Ireland. One notable McCourt mentioned in these records is Dermot McCourt, who received a pardon from Queen Elizabeth I in 1592.
During the Plantation of Ulster in the 17th century, many McCourts were displaced from their ancestral lands and scattered throughout Ireland and beyond. Some McCourts immigrated to the American colonies, with records showing McCourts settling in Pennsylvania and Virginia as early as the late 1700s.
Historically, the McCourt surname has been associated with several notable individuals. One of the earliest was Turlough McCourt (c. 1550-1624), an Irish chieftain and leader of the McCourt clan in County Antrim. Another prominent figure was Reverend James McCourt (1680-1753), a Presbyterian minister and co-founder of the College of New Jersey, which later became Princeton University.
In more recent times, Frank McCourt (1930-2009) gained worldwide recognition for his memoir "Angela's Ashes," which chronicled his impoverished childhood in Limerick, Ireland. The book won the Pulitzer Prize for Biography in 1997.
Other notable McCourts throughout history include John McCourt (1768-1853), an Irish-American soldier who served in the Revolutionary War, and Michael McCourt (1914-1998), an Irish playwright and co-founder of the Abbey Theatre in Dublin.
Demographics
Among Census respondents with the surname Mccourt, the largest self-reported group is White at 93.1%. The next largest groups are Two or More Races (3.0%) and Hispanic (2.6%).
The bar chart below shows how Mccourt 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 Mccourt 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 Mccourt (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.
