Origin
The surname Cowen has its roots in England, with the earliest known records dating back to the 12th century. It is believed to be of Anglo-Saxon origin, derived from the Old English word "cu" or "cou," meaning cow, and "wen" or "winn," meaning meadow or pasture. This suggests that the name may have originally referred to someone who resided near or worked on a cow pasture.
One of the earliest recorded instances of the name can be found in the Pipe Rolls of Northumberland from the year 1197, where a person named Hugh Couen is mentioned. Another early reference appears in the Curia Regis Rolls of Oxfordshire in 1207, which mentions a William Couen.
The Cowen surname has also been linked to various place names in England, such as Cowan Bridge in Lancashire and Cowden in Kent. These place names likely share a similar etymology, further reinforcing the connection between the surname and its association with cattle or pastures.
Throughout history, several notable individuals have borne the Cowen surname. One such person was Robert Cowen (c. 1650-1723), an English clergyman and author who wrote works on theology and philosophy. Another was James Cowen (1775-1860), a British mining engineer and inventor who made significant contributions to the development of the safety lamp used in coal mines.
In the United States, one of the earliest recorded instances of the Cowen surname dates back to the 17th century. John Cowen (1611-1695) was an early settler in Virginia and a prominent Quaker preacher. Other notable American figures with the Cowen surname include Esther Cowen (1857-1964), an American artist and educator, and Zelman Cowen (1919-2011), an Australian legal scholar and academic who served as the Governor-General of Australia from 1977 to 1982.
Overall, the surname Cowen has a rich history spanning several centuries and regions, with its origins firmly rooted in the Anglo-Saxon traditions of England and its close association with cattle and pastures.
Demographics
Among Census respondents with the surname Cowen, the largest self-reported group is White at 86.6%. The next largest groups are Black (4.3%) and Two or More Races (4.1%).
The bar chart below shows how Cowen 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 Cowen 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.
