Origin
The surname Zachos has its origins in Greece, a country with a rich and storied history going back to the ancient period. The name likely hails from regions within Greece such as Thessaly or Epirus, which have historically been inhabited by Greek-speaking populations. The surname itself is derived from older Greek words or names, with "Zachos" possibly being a diminutive or nickname form of the more ancient Greek name Zacharias, which itself means "God has remembered."
The surname Zachos first appeared in historical records during the Byzantine period, a time when surnames began to be more widely used as a means of distinguishing individuals. Manuscripts from this era occasionally make note of individuals with the surname Zachos, usually in the context of military or civic duties. One such record from the 12th century mentions a Byzantine official by the name of Niketas Zachos, highlighting its presence within the administrative echelons of Byzantine society.
As the centuries progressed, the surname continued to appear in various forms of documentation. In the 15th century, an archive from a Venetian-controlled port in Greece records a trader named Demetrios Zachos, indicating the name's use among merchants and the trading class. This period also saw the name appear in tax records and local census documents, which were meticulously kept by the ruling Ottoman Empire following its conquest of Byzantine territories.
Moving into the 18th century, the name Zachos was relatively well established within Greek-speaking regions. In 1752, Christos Zachos, a prominent figure in the local politics of Thessaly, is documented as having played a key role in negotiating trade agreements. Later, in the 19th century, another significant figure, Panagiotis Zachos, born in 1820 and died in 1898, emerged as a notable educator and scholar who contributed extensively to Greek literature and education reforms during the period of the Greek War of Independence and subsequent formation of modern Greece.
The 20th century saw the migration of many Greek families, including those with the surname Zachos, to other parts of the world, particularly the United States and Australia, following the Greek diaspora. However, long before this widespread movement, a documented emigrant named Alexandros Zachos left Greece in the late 19th century to settle in Alexandria, Egypt, where he made a name for himself as a successful businessman.
In terms of famous individuals with the surname, Georgios Zachos, born in 1905 and died in 1973, was a well-known Greek mathematician who contributed to the field of mathematical analysis and played a crucial role in establishing mathematical societies in Greece. Another contemporary figure, Maria Zachos, who lived from 1912 to 1987, was a prominent Greek-American activist, known for her efforts in promoting Greek culture and heritage in the United States.
Ultimately, the surname Zachos has a long and varied history that reflects the broader socio-political changes within Greece and the Greek-speaking world. It is a name that has been associated with various professions, from scholars and traders to officials and activists, and continues to be recognized and respected both in its homeland and abroad.
Demographics
Among Census respondents with the surname Zachos, the largest self-reported group is White at 89.0%. The next largest groups are Two or More Races (5.2%) and Hispanic (3.2%).
The bar chart below shows how Zachos 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 Zachos 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 Zachos (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.
