Origin
The surname Docimo has its origins in Italy, specifically in the regions of Campania and Basilicata. It is believed to have emerged during the medieval period, likely between the 11th and 13th centuries.
The name is derived from the Latin word "docimus," which means "learned" or "erudite." This suggests that the surname may have been given initially to individuals who possessed a high level of education or scholarly knowledge.
One of the earliest known records of the surname appears in the "Codice Diplomatico Barese," a collection of documents from the city of Bari dating back to the 12th century. This document mentions a certain "Petrus Docimo" in the year 1189.
Another early reference can be found in the "Rationes Decimarum Italiae," a papal record of tithes collected in various Italian regions during the late 13th century. This document lists several individuals with the surname Docimo, indicating its presence in multiple towns and villages across southern Italy.
The name Docimo has also been associated with several notable figures throughout history. One of the earliest recorded individuals was Gregorio Docimo, a philosopher and theologian who lived in the 14th century. He was known for his writings on Aristotelian logic and metaphysics.
During the Renaissance period, the name gained prominence with the birth of Giacomo Docimo (1508-1583), a renowned architect and sculptor from Naples. He was responsible for the design and construction of several churches and palaces in the region, including the Chiesa del Gesù Nuovo and the Palazzo d'Avalos.
In the 18th century, Giuseppe Docimo (1725-1798) was a prominent painter and engraver from the town of Acri, in the province of Cosenza. His works, which often depicted religious themes and landscapes, can be found in various churches and museums throughout southern Italy.
Another notable figure was Vincenzo Docimo (1819-1891), a lawyer and politician who served as a member of the Italian Parliament during the late 19th century. He was instrumental in the unification of Italy and played a crucial role in the development of the country's legal system.
More recently, Ferdinando Docimo (1902-1979) was a celebrated Italian sculptor and painter, known for his works in bronze and his depictions of religious figures. His sculptures can be found in various churches and public spaces throughout Italy.
While the surname Docimo may have originated from a specific region in southern Italy, it has since spread to other parts of the country and beyond, carried by individuals and families who have migrated over the centuries.
Demographics
Among Census respondents with the surname Docimo, the largest self-reported group is White at 96.5%. The next largest groups are Two or More Races (2.2%) and Hispanic (0.9%).
The bar chart below shows how Docimo 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 Docimo 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.
