Origin
The surname Troup has its origins in Scotland, with the earliest recorded instances dating back to the 14th century. It is believed to be derived from the Old French word "troupe," meaning a group or troop of people, which in turn comes from the Germanic word "trop," meaning a herd or flock.
One of the earliest known bearers of the name was John Troup, who was mentioned in the Exchequer Rolls of Scotland in 1390. The name was particularly prevalent in the northeastern regions of Scotland, particularly Aberdeenshire and Banffshire.
In the 16th century, the Troup surname appeared in various records, including the Register of the Privy Council of Scotland. One notable figure from this period was Robert Troup, a Scottish minister who was appointed as the rector of the parish of Cullen in 1562.
The name Troup is also associated with several place names in Scotland, such as Trouphead, a coastal headland in Aberdeenshire, and Troup Castle, a ruined 16th-century castle in the same region. These place names likely influenced the spelling and pronunciation of the surname over time.
As the name spread across Scotland and beyond, it underwent various spelling variations, including Troupe, Trowpe, and Trupe. One notable bearer of the name was Sir George Troup (1780-1847), a British naval officer and colonial administrator who served as the Governor of New South Wales from 1819 to 1827.
Another prominent figure was Robert Troup (1757-1832), an American lawyer and jurist who served as a judge in New York and was a founder of the New York Historical Society. He was also an influential figure in the early days of the United States, serving as a delegate to the New York convention that ratified the U.S. Constitution.
In the 19th century, the Troup surname was found in various parts of the English-speaking world, including the United States, Canada, and Australia. One notable Australian bearer of the name was George Troup (1863-1941), a politician who served as the Premier of Western Australia from 1905 to 1909.
Other individuals of note with the Troup surname include James Troup (1828-1904), a Scottish-born Australian politician and businessman who was involved in the early development of the Western Australian mining industry, and John Rose Troup (1847-1919), a Canadian lawyer and politician who served as a Member of Parliament for several terms.
Demographics
Among Census respondents with the surname Troup, the largest self-reported group is White at 81.7%. The next largest groups are Black (11.9%) and Two or More Races (3.4%).
The bar chart below shows how Troup 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 Troup 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 Troup (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.
