Origin
Meaning and origin of Dinapoli
The surname Dinapoli originated in Italy, specifically from the region of Campania in southern Italy, during the medieval period. It is believed to be derived from the words "di Napoli," meaning "from Naples," suggesting that the earliest bearers of this name hailed from the city of Naples.
Dinapoli is a locational surname, a common practice during the Middle Ages when people began to adopt surnames based on their place of origin or residence. This naming convention helped distinguish individuals and families within a community.
One of the earliest known records of the Dinapoli surname can be found in the historical documents of the Kingdom of Naples, which ruled over southern Italy from the 12th to the 18th centuries. These records mention various individuals bearing the name Dinapoli, indicating their presence in the region during that time.
In the late 15th century, a notable figure named Giovanni Dinapoli was mentioned in the annals of the city of Naples for his contributions to the local arts and culture. He was a respected painter and sculptor who left behind several notable works that can still be admired today.
Another prominent individual with the surname Dinapoli was Francesco Dinapoli, a 16th-century scholar and philosopher from Naples who authored several treatises on metaphysics and ethics. His works were widely studied and discussed within academic circles of the time.
The Dinapoli name also found its way into the literary world through the works of Antonio Dinapoli, a 17th-century poet and playwright from Naples. His plays were performed in various theaters across Italy and gained him recognition among the literary elite of the era.
In the 18th century, a noble family by the name of Dinapoli held considerable influence and landholdings in the region of Campania. They were known for their involvement in local politics and their patronage of the arts.
Over time, as migration and immigration patterns evolved, individuals bearing the Dinapoli surname began to disperse across Italy and eventually to other parts of the world, carrying with them the rich cultural heritage and history associated with their name.

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 Dinapoli 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 Dinapoli (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.
