Origin
Meaning and origin of Dagostino
The surname D'Agostino has its origins in Italy, specifically in the southern regions of Campania and Calabria. It likely dates back to the Middle Ages, around the 12th or 13th century. The name is derived from the Italian word "agosto," which means August, referring to the month of the year. This suggests that the surname may have originally been a nickname given to someone born in August or perhaps associated with the month in some significant way.
D'Agostino is a patronymic surname, meaning it was initially derived from the given name of the father or an ancestor. The prefix "D'" in the name indicates the preposition "di," which means "of" or "from" in Italian. Thus, the full name D'Agostino translates to "of August" or "from August."
One of the earliest recorded instances of the name can be found in a document from the city of Naples, dating back to the 14th century. The document mentions a certain "Nicola D'Agostino," suggesting the surname was already in use during that time period in the region of Campania.
In the 15th century, there are records of a notable figure named Giovanni D'Agostino, who was a prominent scholar and philosopher from the city of Salerno. He authored several works on theology and philosophy, contributing to the intellectual discourse of the Renaissance era.
During the 16th century, a notable figure with the surname D'Agostino was Girolamo D'Agostino, an Italian painter and architect born in Naples in 1523. He was renowned for his contributions to the Mannerist style of art and architecture, particularly his work on the Palazzo Reale di Napoli (Royal Palace of Naples).
Another significant figure with the D'Agostino surname was Giacomo D'Agostino, a military leader and strategist who lived in the late 16th and early 17th centuries. He played a crucial role in the defense of the Kingdom of Naples during the Italian Wars, serving under the Spanish rulers of the region.
In the 18th century, a notable D'Agostino was Niccolò D'Agostino, a renowned sculptor from the city of Lecce in the Apulia region of southern Italy. He was known for his exquisite baroque sculptures adorning various churches and monuments in the region.
While the surname D'Agostino is primarily associated with southern Italy, it has also spread to other parts of the country and beyond due to migration and diaspora. However, its origins and earliest recorded instances can be traced back to the southern Italian regions of Campania and Calabria, where it has deep historical roots.

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 Dagostino 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.
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.
