Origin
The surname DITALIA originates from Italy, where it first emerged during the medieval period. It is believed to have derived from the Italian phrase "d'Italia," which translates to "of Italy" or "from Italy." This name likely originated as a way to distinguish individuals who had migrated or traveled from different regions within the Italian peninsula.
One of the earliest recorded instances of the surname DITALIA can be found in the historical records of the Republic of Venice, dating back to the 13th century. It is mentioned in a document from 1278, referring to a merchant named Giovanni DITALIA who traded goods between Venice and the port cities of the Mediterranean.
The DITALIA surname is also found in ancient manuscripts from the city of Florence, where it is linked to a prominent family of bankers and merchants during the Renaissance. Notable figures from this lineage include Antonio DITALIA (1412-1489), a renowned financier who played a significant role in the economic affairs of the Florentine Republic.
In the 16th century, the DITALIA name appears in records from the Kingdom of Naples, where a branch of the family settled and gained influence. One notable individual was Giulio DITALIA (1526-1591), a respected jurist and legal scholar who served as a judge in the Neapolitan court.
As the Italian diaspora spread across Europe and beyond, the DITALIA surname traveled with them. In the 17th century, there are records of a French nobleman named Pierre DITALIA (1638-1702), who traced his ancestry back to Italian immigrants who had settled in the region of Provence.
Another notable figure with the DITALIA surname was Vincenzo DITALIA (1783-1859), an Italian composer and musician who lived during the Romantic era. His works, which included operas and chamber music, were highly regarded and performed across the Italian states and beyond.
Throughout its history, the DITALIA surname has been associated with various occupations and professions, from merchants and bankers to artists and scholars. Its enduring presence in historical records attests to the rich cultural heritage and influence of those who bore this name across the centuries.
Demographics
Among Census respondents with the surname Ditalia, the largest self-reported group is White at 89.1%. The next largest groups are Hispanic (6.7%) and Two or More Races (3.4%).
The bar chart below shows how Ditalia 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 Ditalia 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 Ditalia (2000, 2010, 2020).
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.
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.
