Origin
The surname Cyrus originates from the ancient Persian Empire, specifically from the name Cyrus the Great, the founder of the Achaemenid Empire in the 6th century BC. The name Cyrus is derived from the Persian word "Kuru," which means "the sun."
The name Cyrus gained significance during the reign of Cyrus the Great, who ruled from 559 BC to 530 BC. He was known for his military conquests and for establishing one of the largest empires in ancient history, stretching from the Mediterranean Sea to the Indus River.
The name Cyrus can be found in various ancient texts and inscriptions, including the Behistun Inscription, which is a multi-lingual inscription carved into the rock face of Mount Behistun in modern-day Iran. This inscription, dating back to around 520 BC, details the accomplishments and genealogy of Darius the Great, who was a successor of Cyrus the Great.
One of the earliest known individuals with the surname Cyrus was Cyrus the Younger, a Persian prince and younger son of Darius II, who lived from around 423 BC to 401 BC. He is remembered for his failed attempt to seize the Persian throne from his elder brother, Artaxerxes II.
In later centuries, the name Cyrus appeared in various historical records and chronicles. For example, Cyrus the Philosopher, a Neoplatonist philosopher from the 5th century AD, was a prominent figure in the intellectual circles of his time.
Another notable individual with the surname Cyrus was Cyrus the Great of Persia, a Christian martyr who lived in the 3rd century AD and was executed for his religious beliefs during the reign of the Sassanid king, Bahram II.
The name Cyrus also gained recognition in the Middle Ages, with individuals like Cyrus of Panopolis, a 5th-century Byzantine poet and grammarian, and Cyrus of Alexandria, a 7th-century Melkite Patriarch of Alexandria.
In more recent history, Cyrus is also the surname of several notable figures, including Cyrus N. Ray, an American lawyer and politician who served as the 17th Lieutenant Governor of Indiana from 1893 to 1897, and Cyrus Eaton, a Canadian-American banker and businessman born in 1883, who played a significant role in promoting trade and cultural exchange between the United States and the Soviet Union during the Cold War era.
Demographics
Among Census respondents with the surname Cyrus, the largest self-reported group is White at 54.5%. The next largest groups are Black (34.9%) and Two or More Races (5.4%).
The bar chart below shows how Cyrus 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 Cyrus 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 Cyrus (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.
