Origin
Meaning and origin of Agosto
The surname Agosto originates from Italy, specifically from the regions of Calabria and Sicily. It is derived from the Latin word "Augustus," which means "venerable" or "consecrated." The name is believed to have its roots in ancient Roman times, when the month of August was named after the Roman emperor Augustus Caesar.
During the Middle Ages, the name Agosto was commonly used in southern Italy, particularly in the areas around Naples and Palermo. One of the earliest recorded mentions of the name can be found in the Codex Diplomaticus Cavensis, a collection of medieval documents from the Campania region, dating back to the 11th century.
In the 13th century, a nobleman named Ruggero Agosto was mentioned in the Libro Rosso di Palermo, an important historical document that details the administration of the city during the Sicilian Vespers rebellion against the Angevin rule.
Another notable individual with the surname Agosto was Francesco Agosto, a renowned painter from Palermo who lived in the 16th century. His works can be found in several churches and museums throughout Sicily.
In the 18th century, a Neapolitan scholar named Gennaro Agosto made significant contributions to the study of ancient Roman inscriptions and artifacts. He published several works on the subject, including his magnum opus, "Raccolta di Antiche Iscrizioni Napoletane."
During the 19th century, a prominent figure named Vincenzo Agosto gained recognition as a composer and music teacher in Naples. He wrote several operas and instrumental works that were widely performed in his time.
As the surname Agosto spread throughout Italy and to other parts of the world through immigration, it has maintained its strong connections to its southern Italian roots, particularly in the regions of Calabria and Sicily.

The bar chart below shows how Agosto 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 Agosto 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 Agosto (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.
