Origin
The surname Karagianis is of Greek origin, with roots tracing back to the Byzantine era. It is believed to have originated from the Greek word "karagianni," which means "black man" or "dark-skinned person." This suggests that the name was initially given as a nickname or descriptive term for individuals with darker complexions.
Karagianis is a common surname found in various regions of Greece, particularly in the Peloponnese peninsula and the islands of the Aegean Sea. The earliest recorded instances of this surname can be traced back to the 15th century, when it appeared in various historical documents and records from that era.
One notable historical reference to the surname Karagianis can be found in the archives of the Monastery of Vatopedi on Mount Athos, a renowned center of Orthodox monasticism. These records date back to the late 15th century and mention individuals bearing the Karagianis surname as residents or visitors to the monastery.
During the 16th and 17th centuries, the Karagianis surname was particularly prevalent in the Mani region of the Peloponnese peninsula. Several individuals with this surname were involved in the Greek War of Independence against the Ottoman Empire in the early 19th century, including Georgios Karagianis (1788-1837), a renowned military leader and revolutionary figure.
Another famous bearer of the Karagianis surname was Ioannis Karagianis (1827-1902), a Greek politician and diplomat who served as the Minister of Foreign Affairs for Greece in the late 19th century.
In the 20th century, Konstantinos Karagianis (1906-1988) was a prominent Greek sculptor and artist, known for his monumental public works and contributions to the cultural life of Athens.
Historically, the surname Karagianis has been associated with various place names and older spellings, reflecting the regional variations and linguistic influences throughout Greece. For example, in some regions, the name was written as "Karagiannis" or "Karaghianni," reflecting local dialects and pronunciation variations.
While the Karagianis surname is predominantly Greek in origin, it has also been adopted by individuals of Greek descent living in other parts of the world, particularly in the Greek diaspora communities across Europe, North America, and Australia.
Demographics
Among Census respondents with the surname Karagianis, the largest self-reported group is White at 98.3%. The next largest groups are Hispanic (0.8%) and Two or More Races (0.8%).
The bar chart below shows how Karagianis 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 Karagianis 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.
