Origin
Meaning and origin of Giuliani
The surname Giuliani originated in Italy during the medieval period. It is an Italian patronymic surname derived from the personal name Giuliano, which is the Italian form of the Roman name Julianus. Julianus was a derivative of the name Julius, which was derived from the ancient Roman family name Julii.
The name Giuliani first appeared in records from the 13th century in various regions of Italy, including Tuscany, Lombardy, and the Veneto. It was particularly prevalent in the cities of Florence, Siena, and Venice, where many notable individuals bore this surname.
One of the earliest recorded instances of the name Giuliani can be found in the Florentine Codex of 1298, which mentions a merchant named Giovanni Giuliani. Another early reference is in the Venetian Chronicles of 1322, which mentions a nobleman named Marco Giuliani.
In the 15th century, the Giuliani family of Florence produced several notable figures, including the humanist scholar Pietro Giuliani (1420-1490) and the renowned artist Girolamo Giuliani (1445-1512), whose frescoes can still be seen in the Basilica of Santa Croce in Florence.
The Giuliani surname also has a connection to the city of Siena, where a family of that name played a prominent role in the city's political and cultural life during the Renaissance. One notable member was the poet and diplomat Pandolfo Giuliani (1475-1550), who served as an ambassador for the Republic of Siena.
In the 16th century, the Venetian branch of the Giuliani family produced several notable figures, including the architect and sculptor Jacopo Giuliani (1510-1578), who contributed to the construction of the Doge's Palace in Venice.
Other notable individuals with the surname Giuliani include the Italian composer and violinist Mauro Giuliani (1781-1829), the Italian painter and engraver Giovanni Battista Giuliani (1763-1824), and the Italian scholar and writer Giambattista Giuliani (1818-1884), who was a prominent figure in the Italian Risorgimento movement.
These are just a few examples of the many individuals who have borne the surname Giuliani throughout history, reflecting its deep roots and significance in various regions of Italy.

The bar chart below shows how Giuliani 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 Giuliani 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.
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.
