Origin
The surname DeRosa has its origins in Italy, specifically in the regions of Campania and Lazio. It is believed to have emerged in the late medieval period, around the 13th or 14th century. The name is derived from the Italian phrase "de rosa," which translates to "of the rose." This suggests that the name may have initially been a descriptive name given to someone who lived near or was associated with a rose garden or rose-related trade.
One of the earliest recorded instances of the name can be found in the Codice Diplomatico Barese, a collection of historical documents from the city of Bari, dating back to the 13th century. In these records, the name appears as "de Rosa" and is associated with individuals from the surrounding areas of Bari and Naples.
Another notable mention of the name can be found in the Cedolario Napoletano, a collection of records from the Kingdom of Naples, where the name is listed as "DeRosa" in the 15th century. This suggests that the spelling variation with the capitalized "R" had already emerged by that time.
In terms of historical figures, one of the earliest notable individuals with the surname DeRosa was Giovanni DeRosa, a renowned painter from Naples who lived in the late 16th and early 17th centuries. Another notable figure was Francesco DeRosa, a philosopher and scholar from Campania who lived in the late 17th century and contributed to the Enlightenment movement in Italy.
Moving forward in time, the name appears in various historical records and documents across Italy. For example, in the 18th century, there was a notable DeRosa family in the town of Sorrento, known for their involvement in the local lemon trade. Additionally, in the 19th century, Giuseppe DeRosa was a prominent politician and lawyer from Naples who played a role in the Risorgimento movement for Italian unification.
As for place names and older spellings, the name is often associated with the town of Rosa in the province of Salerno, Campania. It is possible that the name was derived from this place name or that individuals from this town adopted the surname DeRosa. Other variations of the spelling include "De Rosa," "Derosa," and "Di Rosa."
Throughout history, there have been several other notable individuals with the surname DeRosa, including Antonio DeRosa, an Italian-American painter and sculptor from the early 20th century; Maria DeRosa, an Italian actress and singer from the mid-20th century; and Luigi DeRosa, an Italian footballer who played in the 1960s.
Demographics
Among Census respondents with the surname Derosa, the largest self-reported group is White at 88.9%. The next largest groups are Hispanic (7.0%) and Two or More Races (2.3%).
The bar chart below shows how Derosa 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 Derosa surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
