Origin
The surname Passas is believed to have originated in Greece, with roots dating back to the Byzantine era. It is thought to be derived from the Greek word "pasas," which means "pasha" or "governor," indicating a possible connection to an influential family or position of authority during that time.
One of the earliest recorded mentions of the name Passas can be found in the archives of the Monastery of Vatopedi on Mount Athos, where a monk named Ioannis Passas is listed as a scribe in the 14th century. This suggests that the name was already in use among Greek families during the medieval period.
In the 16th century, a document from the island of Naxos references a landowner named Georgios Passas, indicating that the name had spread to other parts of the Greek archipelago by that time. Additionally, there are records of a merchant named Alexandros Passas who traded in the Aegean Sea during the 17th century.
The name Passas also appears in historical texts from the Ottoman Empire, where it was sometimes rendered as "Pasha" or "Pasha-zade," reflecting the Turkish influence in the region. One notable figure was Mehmet Pasha, a military commander who served in the Ottoman army during the 16th century.
In more recent times, several individuals with the surname Passas have gained recognition in various fields. Dimitrios Passas (1859-1935) was a Greek politician and diplomat who served as the Mayor of Athens and later as the Greek Ambassador to the United States. Another notable Passas was Ioannis Passas (1920-2002), a renowned Greek poet and translator whose works explored themes of love, loss, and the human condition.
Other notable individuals with the surname Passas include:
1. Nikolaos Passas (1856-1923), a Greek lawyer and politician who served as a member of the Greek parliament.
2. Konstantinos Passas (1892-1967), a Greek Army officer who fought in the Balkan Wars and World War I.
3. Eleni Passas (1928-2022), a Greek painter and sculptor known for her abstract works.
4. Georgios Passas (1957-present), a Greek businessman and philanthropist who has supported various charitable organizations.
5. Theodoros Passas (1973-present), a Greek academic and expert in the field of criminology and security studies.
While the surname Passas has its roots in Greece, it has since spread to other parts of the world through migration and diaspora communities, carrying with it a rich history and cultural significance.
Demographics
Among Census respondents with the surname Passas, the largest self-reported group is White at 84.7%. The next largest groups are Two or More Races (6.8%) and Hispanic (3.4%).
The bar chart below shows how Passas 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 Passas 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.
