Origin
Meaning and origin of Koutros
The surname KOUTROS is of Greek origin, originating in the regions of the Greek mainland and islands during the Byzantine era. It is derived from the Greek word "koutros," which means "dwarf" or "short person." This suggests that the name may have initially been a descriptive nickname given to someone of short stature.
The earliest recorded instances of the name KOUTROS can be traced back to the 15th century in various historical documents and records from the Greek-speaking regions of the Byzantine Empire. One notable example is found in a census record from the island of Crete dated 1472, where a certain Georgios Koutros is listed as a landowner.
In the 16th century, the name appears in a maritime register from the island of Chios, where a shipowner named Nikolaos Koutros is mentioned. This suggests that the name was also present among the Greek maritime communities during this period.
During the 17th and 18th centuries, the name KOUTROS can be found in various church records and legal documents from the Greek mainland, particularly in the regions of the Peloponnese and Central Greece. One notable figure from this era is Ioannis Koutros, a scholar and teacher who lived in the town of Nafplion in the late 18th century.
In the 19th century, the name gained more prominence as Greece gained independence from the Ottoman Empire. One significant figure bearing the name KOUTROS was Dimitrios Koutros, a military officer who fought in the Greek War of Independence (1821-1829) and later served as a member of the Greek Parliament.
Another notable individual was Alexandros Koutros, a prominent lawyer and judge who lived in Athens in the late 19th century. He played a crucial role in shaping the legal system of modern Greece.
In the early 20th century, the name KOUTROS continued to be present in various parts of Greece. One notable figure was Georgios Koutros, a renowned architect who designed several significant buildings in Athens and other Greek cities.
Throughout its history, the surname KOUTROS has been associated with various professions and fields, including agriculture, maritime activities, education, law, and architecture. While it may have originated as a descriptive nickname, it has evolved into a respected surname with a rich heritage in Greek culture and society.
Demographics
Ancestry and ethnicity for Koutros
Among Census respondents with the surname Koutros, the largest self-reported group is White at 91.3%. The next largest groups are Hispanic (8.7%).
The bar chart below shows how Koutros 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 Koutros surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?
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.
