Origin
Meaning and origin of Tiberi
The surname Tiberi originated in Italy, with its roots tracing back to the ancient Roman period. It is believed to be derived from the Latin name Tiberius, which was a Roman family name derived from the Latin word "Tiberis," meaning the Tiber River. The Tiber River flows through the city of Rome, and the name Tiberius was associated with the Tiberius family, one of the most prominent patrician families of ancient Rome.
One of the earliest recorded references to the name Tiberi can be found in the Codex Diplomaticus Cavensis, a collection of medieval documents from the Abbey of Cava in southern Italy, dating back to the 11th century. This document mentions individuals with the surname Tiberi, suggesting that the name was already in use during the Middle Ages.
In the 13th century, the name Tiberi appeared in the records of the Republic of Siena, a prominent city-state in Tuscany. The Tiberi family was a noble family that held significant influence in the political and cultural life of Siena during this period.
During the Renaissance, the Tiberi family produced several notable figures. One of the most prominent was Bonifacio Tiberi (1470-1537), an Italian painter and architect who worked in Rome and other Italian cities. His works can be found in various churches and palaces across Italy.
Another notable individual with the surname Tiberi was Giovanni Battista Tiberi (1556-1635), an Italian Catholic prelate who served as the Bishop of Vico Equense from 1600 to 1635.
In the 18th century, the Tiberi family continued to play a role in Italian history. Andrea Tiberi (1725-1796) was an Italian architect and urban planner who worked on several projects in Rome, including the restoration of the Palazzo della Consulta.
Moving into the 19th century, the Tiberi family produced several notable writers and intellectuals. One example is Enrico Tiberi (1826-1896), an Italian historian and writer who published works on the history of Rome and the Italian unification movement.
Throughout its long history, the surname Tiberi has maintained a strong connection to its Roman roots and has been associated with various notable individuals across different fields, including art, architecture, religion, and literature.

The bar chart below shows how Tiberi 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 Tiberi surname at the time of the 2020 Census, not any inherent property of the name itself.

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.

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
