Origin
Meaning and origin of Calabro
The surname Calabro originated in Italy, specifically in the region of Calabria located in the southernmost part of the Italian peninsula. The name can be traced back to the late medieval period, around the 12th to 14th centuries.
Calabro is believed to have derived from the Italian word "Calabrese," which means "a person from Calabria." This region was known for its rugged terrain, mountainous landscapes, and coastal areas along the Ionian and Tyrrhenian Seas. The name was likely adopted by individuals who migrated from Calabria to other parts of Italy or abroad.
One of the earliest recorded instances of the surname Calabro can be found in a document from the city of Cosenza, Calabria, dated 1327. This document mentions a certain "Giovanni Calabro," who was a landowner in the region.
In the 15th century, a notable figure bearing the name Calabro was Girolamo Calabro, a humanist scholar and writer born in Reggio Calabria around 1420. He was known for his works on philosophy and classical literature.
Another prominent individual with this surname was Gian Battista Calabro, a painter from the Baroque period who lived in Naples during the late 16th and early 17th centuries. He was known for his religious paintings and frescoes adorning various churches in the city.
During the 18th century, there was a renowned Italian composer and violinist named Niccolò Calabro, who was born in Palermo, Sicily, in 1718. He was a prolific composer of operas and instrumental works, and his compositions were highly regarded throughout Europe.
In the 19th century, a notable figure with the surname Calabro was Giuseppe Calabro, an Italian politician and lawyer born in Catanzaro, Calabria, in 1825. He served as a member of the Italian Parliament and was actively involved in the unification movement of Italy.
Throughout its history, the surname Calabro has also been associated with various place names and variations in spelling, such as Calabria, Calabrese, Calabrese, and Calabresi, reflecting the strong connection to the region of Calabria.

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 Calabro surname at the time of the 2020 Census, not any inherent property of the name itself.

Is this page using the latest Census data?
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 Calabro (2000, 2010, 2020).
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
