Origin
Meaning and origin of Didomenico
The surname DiDomenico has its origins in Italy, tracing back to the medieval period. It is a compound name derived from the Italian words "di" meaning "of" and "Domenico," a personal name meaning "belonging to the Lord." This surname likely originated as a way to identify someone who lived near a church or property dedicated to Saint Dominic or had some association with the Dominican order.
One of the earliest recorded instances of the surname DiDomenico can be found in the medieval records of the city of Siena, in the region of Tuscany, dating back to the 13th century. These records mention a family by the name of DiDomenico who were involved in the local wool trade, a prominent industry at the time.
In the 14th century, the surname DiDomenico appeared in the historic records of the city of Venice, where a notable merchant and banker named Giovanni DiDomenico was mentioned as having played a significant role in the city's economic affairs during that era.
The surname DiDomenico has also been associated with several notable individuals throughout history. One such person was Vincenzo DiDomenico, an Italian painter and architect who lived in the 16th century and was renowned for his contributions to the Renaissance art and architecture of Naples.
Another prominent figure was Francesco DiDomenico, an Italian mathematician and astronomer who lived in the 17th century and made significant advancements in the field of celestial mechanics. He is particularly known for his work on the orbits of comets and his collaboration with the renowned astronomer Giovanni Cassini.
In the 18th century, a composer and musician named Gaetano DiDomenico gained recognition for his compositions for the harpsichord and his contributions to the development of the Italian opera tradition.
Throughout the centuries, the surname DiDomenico has also been associated with various places and locations, often reflecting the areas where families bearing this name settled or had roots. For instance, there is a town called San Domenico di Ficarra in the province of Messina, Sicily, which may have been named after a notable DiDomenico family or individual from that region.
While the surname DiDomenico has its origins in Italy, it has also been adopted and carried by families in other parts of the world, particularly in areas with significant Italian immigration, such as the United States, Canada, and Australia.

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.

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

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 Didomenico (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.
