Origin
The surname Cork originates from England, where it first emerged in the 13th century. It likely derives from the Old English word "corc," which means "cork tree" or "cork oak." This suggests that the name may have originally referred to someone who lived near a cork oak tree or a location associated with cork trees.
In medieval times, Cork was a locational surname, indicating that the bearer hailed from a place called Cork. This could refer to various locations in England, such as Cork in Dorset or Cork Street in London. The earliest known record of the surname is found in the Hundred Rolls of Oxfordshire in 1273, where it appears as "de Cork."
The name Cork is also closely linked to the city of Cork in Ireland. While the city's name is of uncertain origin, it may have been named after the Cork family who held lands in the area during the Anglo-Norman invasion of Ireland in the 12th century. The earliest recorded instance of the surname in Ireland dates back to 1343, when John de Cork is mentioned in the Pipe Rolls of Cloyne.
Historically, the surname Cork has been associated with several notable individuals. One of the earliest was Sir John de Cork, a 14th-century English knight who served as the Sheriff of Somerset and Dorset in 1356. Another notable bearer was Edmund Cork (1542-1609), an English lawyer and Member of Parliament who served as the Recorder of Bristol.
In the 17th century, Sir Richard Cork (1602-1668) was a prominent English merchant and Member of Parliament for Lyme Regis. His grandson, Richard Cork (1672-1723), inherited the family estate and became the first Earl of Cork and Orrery in 1698.
Moving into the 18th century, Nathaniel Cork (1726-1796) was a British Royal Navy officer who served as the Commander-in-Chief of the Leeward Islands Station during the American Revolutionary War.
One of the most famous individuals with the surname Cork was the British artist and art critic Richard Cork (1947-present), known for his contributions to contemporary art criticism and his writings on artists such as Pablo Picasso and Henri Matisse.
Demographics
Among Census respondents with the surname Cork, the largest self-reported group is White at 69.0%. The next largest groups are Black (23.2%) and Two or More Races (4.7%).
The bar chart below shows how Cork 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 Cork 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.
